The diploid number of a horse (Equus caballus) is 64 which includes 36 acrocentric autosomes. The ass (Equus asinus) has 62 chromosomes including 22 acrocentric autosomes.
A) Predict the number of chromosomes that would be found in the hybrid offspring (mule) produced by mating a male ass (jack) to a female horse (mare).
B) Why are mules usually sterile (incapable of producing viable gametes)?
