What does dominance mean in genetics?
"Mendelian Inheritance" by Bruce Korf, MD for OPENPediatrics
Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus.
The first allele is dominant and the second allele is recessive.
Dominance is a key concept in Mendelian inheritance and classical genetics.
Autosomal Recessive vs. Autosomal Dominance
Hybrid, offspring of parents that differ in genetically determined traits. The term hybrid, therefore, has a wider application than the terms mongrel or crossbreed, which usually refer to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species.
1a : to state or declare positively and often forcefully or aggressively The suspect continued to assert his innocence. b : to compel or demand acceptance or recognition of (something, such as one's authority) … the confrontations that inevitably occur [between orangutans] when several males try to assert dominance … —
Social dominance orientation (SDO) is a personality trait which predicts social and political attitudes, and is a widely used social psychological scale. People high in SDO also prefer hierarchical group orientations. Often, people who score high in SDO adhere strongly to belief in a "dog-eat-dog" world.
Autosomal Recessive Inheritance - Genetics
Dogs are often described as being “dominant” which is an incorrect usage of the term. Dogs that use aggression to “get what they want” are not displaying dominance, but rather anxiety-based behaviors, which will only increase if they are faced with verbal and/or physical threats from their human owners.
Dominance aggression is a manifestation of inappropriate responses to specific situations related to control. It usually develops in dogs at social maturity, between 18 and 36 months of age. Dogs with dominance aggression are dangerous because the problem is caused by a struggle with people over control.
Signs that your dog's aggression or aggressive behavior is dominance related may include signs such as: Aggressive behaviors in response to verbal corrections. Aggressive responses triggered by eye contact. Attempts to herd other pets or humans using nipping. Guarding behavior of toys or food. Inappropriate mounting.
From Wikipedia, the free encyclopedia. A suppressor mutation is a second mutation that alleviates or reverts the phenotypic effects of an already existing mutation in a process defined synthetic rescue. Genetic suppression therefore restores the phenotype seen prior to the original background mutation.
The 'dominance' theory of dog behaviour assumes that dogs are motivated to achieve a higher social 'status' relative to other dogs or people, and that this desire may lead them to show behaviours such as aggression in order to achieve control.

Atrial fibrillation as a cause or consequence of DCM is assumed for certain breeds. The causes of DCM are widely unknown in dogs. A genetic basis for this heart disease seems to exist. In humans mutations in several genes responsible for DCM have been identified.
It is not a hereditary thyroid disorder. Therefore, any dog that has significant levels of blood-thyroid autoantibodies is considered genetically affected with hypothyroidism, and to carry a gene (or genes) that cause the disorder.
A juvenile form of DCM has been found in Portuguese Water Dogs and Doberman Pinscher Dogs. Atrial fibrillation as a cause or consequence of DCM is assumed for certain breeds. The causes of DCM are widely unknown in dogs. A genetic basis for this heart disease seems to exist.
Genes have pairs of alleles (one from each parent) that are located at specific sites (loci) on a chromosome. When dogs breed, the mother and father each randomly contribute one allele from each locus, giving each allele a 50% chance of being passed on to the pups.
Incomplete Dominance, Codominance, Polygenic Traits, and Epistasis!
Pannus is a thought to be a hereditary condition that develops as the pet ages. Breeds such as German shepherds, Border Collies and Long-Haired dachshunds are the most commonly affected breeds, but pannus can occur in any breed.
🔤 Meaning. As its official name reveals, 😏 Smirking Face represents the facial expression of a smirk. It's used to communicate a range of feelings, including smugness, self-confidence, self-indulgence, mischief, cheeky humor, and general satisfaction.
Having a dog with one or both testicles retained (cryptorchidism) is one of the most common congenital developmental defects in purebred dogs. Cryptorchidism is heritable and is a sex-limited autosomal recessive trait in dogs. The incidences of cryptorchidism in dogs range from 1.2 to 10%.
An overbite is a genetic, hereditary condition where a dog's lower jaw is significantly shorter than its upper jaw. This can also be called an overshot jaw, overjet, parrot mouth, class 2 malocclusion or mandibular brachynathism, but the result is the same – the dog's teeth aren't aligning properly.
Some rarer kinds of meningitis, however, are the result of inherited abnormalities of the canine immune system. Three kinds of meningitis are known to be related to inherited traits: beagle pain syndrome, aseptic meningitis and necrotizing meningo-encephalitis (also known as “pug encephalitis”).
Hernias in dogs can be either congenital or acquired. Congenital hernias are those that are present at birth; they may or may not have a hereditary component. Naval (umbilical) hernias can be hereditary or can be caused by the umbilical cord being cut too closely to the abdominal wall shortly after a puppy is born.
Face with tears of joy is an emoji that represents someone laughing so hard that tears are streaming down their face. It can be used as an emotional-tone marker to express amusement and joviality when someone says or does something funny or embarrassing.
😳 Flushed Face. A yellow face with raised eyebrows, a small, closed mouth, wide, white eyes staring straight ahead, and blushing cheeks. Intended to depict such feelings as embarrassment, but meaning very widely varies. Other senses include flattery, surprise, disbelief, admiration, affection, and excitement.
A common usage of the red heart emoji is to convey affection or love. In this slogan, the heart is a stand-in for the word love. If a text says “I ❤️ u,” it can be read as either “I love you” or “I heart you.” In another sense, the red heart emoji expresses gratitude or thanks.
It means you've messed up big time I really don't care if you text all day Smiling big I'm in the middle of something Eat u out It's means I'm super happy It means that I absolutely love what you just texted. Cheesy smile It's an emoji that's cold.
😶 Face Without Mouth. A yellow face with simple, open eyes and no mouth, as if at a loss for words. Meaning widely varies, but commonly conveys speechlessness, humility, and silence. May also convey moderately negative emotions, such as disappointment, frustration, or sadness.
🔤 Meaning. 😬 Grimacing Face conveys a wide range of moderately negative emotions, including disapproval, discomfort, and disgust. Because its toothy mouth can resemble a grin from a distance, 😬 Grimacing Face is occasionally used to show—or confused for—excitement, laughter, or happiness.
Genomic imprinting is an epigenetic phenomenon that causes genes to be expressed in a parent-of-origin-specific manner. Forms of genomic imprinting have been demonstrated in fungi, plants and animals. As of 2014, there are about 150 imprinted genes known in the mouse and about half that in humans.
Dog Coat Colour Genetics. Brindle is one of the recessive genes on the K locus. There are three K locus genes - K (dominant black, sometimes written as KB), kbr (brindle) and k (non-solid black - allows A locus to be expressed). Brindle typically appears as black stripes on a red base.
Example 1: “In animal behavior, dominance is defined as a relationship between individuals that is established through force, aggression and submission in order to establish priority access to all desired resources (food, the opposite sex, preferred resting spots, etc.).
Most animals with hydrocephalus are puppies with congenital anomalies that lead to hydrocephalus; they are not born with it but they are born with the anatomical problems that quickly lead to hydrocephalus. In puppies, this is generally a genetic problem related to the breed.
Since cryptorchidism is a genetic disease, it is not recommended to breed dogs with this condition, as the father could pass it along to his offspring. This is actually assuming the father can reproduce. Most dogs with bilateral cryptorchidism (meaning that both testicles are retained) are sterile.
In most breeds, the cause of IBD is likely not strictly genetic or environmental, Allenspach says. Affected dogs within a breed probably share one or more genetic mutations, but the presence of the mutation alone does not mean the dog will develop IBD.
Though idiopathic epilepsy can occur in any breed, it is considered an inheritable disease in many breeds and in some breeds a genetic basis has been identified. Therefore, dogs diagnosed with idiopathic epilepsy should not be used for breeding.
Dog Aggression Toward Owner Can Be Due to Genetic Predisposition. Additionally, this fear and aggression is not the same as when those feelings are directed toward unfamiliar dogs and humans. Twelve genes are associated with these traits, according to the press release.
BACKGROUND: Intervertebral disc degeneration (IVDD) is considered a multifactorial disease that is influenced by both environmental and genetic factors. The last two decades of research strongly demonstrate that genetic factors contribute about 75% of the IVDD etiology.
Dominance hierarchy, a form of animal social structure in which a linear or nearly linear ranking exists, with each animal dominant over those below it and submissive to those above it in the hierarchy. Direct conflict is rare; an animal usually steps aside when confronted by one of higher rank.
In studies of social animals, the highest ranking individual is sometimes designated as the alpha. Males, females, or both, can be alphas, depending on the species. The individual with alpha status sometimes changes, often through a fight between the dominant and a subordinate animal.
Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. Often the dominant allele codes for a functional protein whereas the recessive allele does not.
Further, specific breeds of dogs have an increased risk of ACL rupture, which suggests a genetic predisposition. Knee cap issues can also predispose a dog to rupture their ACL. These knee cap issues include a luxating patella. ANY dog at any age of any breed, lineage, or mutt can tear an ACL.
Because black is dominant, a dog with even just one K gene will be solid black. A dog with two k genes (i.e. homozygous for k) will be able to show tan markings. The only way phaeomelanin can be added to the coat of a dog with the dominant black gene is through the e gene (E locus) - recessive red.
What Causes Cherry Eye in Dogs? The exact cause of Cherry Eye is, unfortunately, unknown. However, given the prevalence in certain breeds there is thought to be a genetic component which may cause a weakening in the fibrous attachment that holds the gland in place and allows it to prolapse easily.
Larger breeds have less genetic predisposition to problems with the kneecap. They typically have a nice, deep groove for the patella to seat in. Large and giant breed dogs with hip dysplasia often have a secondary condition of luxating patella caused by the malformation of the hip joint.
Dogs, like people, can develop a variety of bladder and kidney stones. Urate bladder stones are most commonly the result of a genetic abnormality that causes a defect in the metabolism of uric acid. Other causes of urate bladder stones include liver diseases such as portosystemic shunts.
While a dog's genetics may predispose it to behave in certain ways, genetics do not exist in a vacuum. Because of the impact of experience, the pit bull specifically bred for generations to be aggressive may not fight with dogs and the Labrador retriever bred to be a service dog may be aggressive toward people.
A genetic disorder is a condition that is caused by an abnormality in an individual's DNA. Abnormalities can be as small as a single-base mutation in just one gene, or they can involve the addition or subtraction of entire chromosomes.
