Question

Why are intergeneric crosses almost unknown and interspecific crosses rare in nature?


​

Answer 1

Answer:

. Male and female animals of two varied related species are mated in interspecific crosses and their fertility varies. In a certain case, the progeny may display desirable features of both the parents and may be of economic value. Example – A mule, whereas the female counterparts can breed with the species which is rare in nature. Intergeneric hybridization, on the other hand, is the cross of two different genera which is almost unknown in nature. They never form the complete zygote and are infertile.
