The mule is a hybrid between a female horse or mare (2n=64) and a male donkey or jackass (2n=62). Since the mare contributes 32 chromosomes in her egg and the jackass contributes 31 chromosomes in his sperm, the mule has a diploid number of 63.
How many chromosomes do mules have?
Mules are a hybrid of two species – a female horse and a male donkey – so they end up with an odd number of chromosomes. A horse has 64 chromosomes and a donkey has 62. A mule inherits 63. An even number of chromosomes is needed to divide into pairs and reproduce.
