It is the reciprocal cross to the more common mule, which is the product of a male donkey, a jack, and a female horse, a mare. The hinny is distinctive from the mule both in physiology and temperament as a consequence of genomic imprinting. Hinnies are the reciprocal cross to the more common mule. Comparatively, the average hinny has a smaller stature, shorter ears, stronger legs, and a thicker mane than the average mule. The distinct
Extended female sexuality males. According to Hrdy's hypothesis, extended female sexuality is an adaptive process with an aim of creating paternity confusion in their male counterparts. Paternity confusion refers to the male being unsure as to whether offspring are genetically his own. If the female mates with different males (at all points of her ovarian cycle) whilst concealing fertility, then the males will inevitably have paternity confusion. Paternity confusion is proposed to be an adaptive function for preventing infanticide. Thus, if the female can successfully create paternity confusion, males will be less likely to kill her offspring, as the lack of paternity certainty
