Question

What happens when the members of the same genus but different species interbreed?

Answer 1

Members of different species belonging to the same genus can interbreed, but they usually produce sterile/infertile offspring. The offspring usually has characteristics of both the parents. The offspring are not very short-lived.

The most well-known example is that of the mule, which is the product of a cross between a male donkey (Equus asinus) and a female horse (Equus caballus).
