"A mule gets 32 horse chromosomes from mom and 31 donkey chromosomes from dad for a total of 63 chromosomes. (A horse has 64 chromosomes and a donkey has 62)."- the odd number of chromosomes (and difference in size and sequence) do not allow for meiosis to take place, and thus egg and sperm are not made.-brie
