Donkey than hinnies, making them more desirable for breeders to produce. The offspring of a zebra-donkey cross is called a zonkey, zebroid, zebrass, or zedonk; "zebra mule" is an older term, but still used in some regions today. The foregoing terms generally refer to hybrids produced by breeding a male zebra to a female donkey. "Zebra hinny, zebret" and "zebrinny" all refer to the cross of a female zebra with a male donkey. Zebrinnies are rarer than zedonkies because female zebras in captivity are most valuable when used to produce full-blooded zebras. There are not enough female zebras breeding in captivity
One-male group offspring, compared to a noninbred offspring. Inbreeding depression resulted from the decreased genetic diversity within this population, meaning that the population as a whole experienced a decrease in fitness (i.e. reproductive success). Unlike infanticide, the high occurrence of inbreeding in one-male groups is a disadvantageous to both the females and males in the group. Experiments involving the hamadryas baboon species ("hamadryas hamadryas") provide evidence of feeding advantages for male and female members of one-male groups. However, the findings of feeding advantages were only evident when these one-male groups formed clans. It has been shown that males from single one-male groups
