Wildebeest of her own, "Nelly Gnu and Daddy Too". Wildebeest Wildebeests, also called gnus, are antelopes in the genus Connochaetes. They belong to the family Bovidae, which includes antelopes, cattle, goats, sheep, and other even-toed horned ungulates. "Connochaetes" includes two species, both native to Africa: the black wildebeest or white-tailed gnu ("C. gnou"), and the blue wildebeest or brindled gnu ("C. taurinus"). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black
Wildebeest studied in a male and a female wildebeest. In the female, all except a pair of very large submetacentric chromosomes were found to be acrocentric. Metaphases were studied in the male's chromosomes, and very large submetacentric chromosomes were found there, as well, similar to those in the female both in size and morphology. Other chromosomes were acrocentric. The X chromosome is a large acrocentric and the Y chromosome a minute one. The two species of the wildebeest are known to hybridise. Male black wildebeest have been reported to mate with female blue wildebeest and vice versa. The differences in social
