Can two different species produce fertile offspring?

Species and the Ability to Reproduce. A species is a group of individual organisms that interbreed and produce fertile, viable offspring. Interbreeding in Dogs: Dogs of different breeds still have the ability to reproduce.

Why can't different species produce fertile offspring?

Why can some interbreeding species produce fertile offspring, while others—like horses and donkeys—cannot? Horses have 64 chromosomes, while donkeys have 62, and when they mate, their chromosomes don't pair up properly, inhibiting meiosis in their offspring. As a result, mules are sterile.

What is the term for a group of organisms that can reproduce and have fertile offspring?

A species is a group of similar organisms that can breed with one another to produce fertile offspring. For example, humans are one species and dogs are another species. Individuals of the same species can reproduce to make more individuals of the same species.

It depends. A feral dog may get along with a wolf if both are amenable. Some of the variables would be the age, sex, pack status, hunger, and previous socialization of both animals. Some humans seem determined to cross breed wolves and dogs just as they cross other equines and zebras (zebroids).
