Question: how many chromosomes would be present in a diploid cell of a mule?
Answer: The brown mouse would be BB and the white mouse bb. Mules (male) and hinnies (female) are bred by crossing a horse and a donkey. Horses have a diploid number of 62 chromosomes and donkeys have 64 chromosomes. Propose why mules and hinnies do not produce gametes and are sterile (cannot produce offspring).
