What Prevents Mules from Having Offspring

Question

What prevents mules from having offspring?
A) They don't develop sex organs.
B) They are all males.
C) They can't produce eggs and sperm.
D) Each mule produced is a different species from other mules.

Accepted Answer

Mules are a hybrid offspring of a male donkey and a female horse. As a result, they inherit an uneven number of chromosomes from each parent, which often leads to infertility. Mules are unable to produce viable gametes (eggs or sperm) due to their odd number of chromosomes, preventing them from reproducing on their own.
