Hinny isA) Fertile hybrid between Stallion and female donkeyB) Sterile hybrid between stallion and female donkeyC) fertile hybrid between mare and male donkeyD) Fertile hybrid between stallion and male donkey

The correct answer is:

B) Sterile hybrid between stallion and female donkey

Explanation: A hinny is a hybrid offspring resulting from the mating of a male donkey (jack) and a female horse (mare). This is similar to a mule, which is a hybrid between a male horse (stallion) and a female donkey (jenny).

However, hinnies are typically sterile due to the differences in the chromosome numbers of the horse and the donkey. This sterility is a characteristic of most hybrids between different species or subspecies.

Thus, the correct answer is B, as it describes a hinny as a sterile hybrid between a stallion and a female donkey, though the definition should ideally refer to a jack (male donkey) and a mare (female horse). The given options may not be completely accurate, but based on typical hybrid naming conventions, option B is the closest correct choice.
