A mule gets 32 horse chromosomes from mom and 31 donkey chromosomes from dad for a total of 63 chromosomes.
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.
How can a mule have 64 chromosomes?
Mules result from the breeding of a male donkey with a female horse. Donkeys have 62 chromosomes, horses have 64, and mules have 63. … In a process known as nuclear transfer, they inserted the mule DNA into a horse egg cell that contained no genetic material.
How many pairs of chromosomes does a donkey have?
Not so with mules and hinnies. Horses, you see, have 32 pairs of chromosomes while a donkey has only 31. As a result, their offspring will inherit 32 horse chromosomes and 31 donkey chromosomes, which, as you can see, leaves one chromosome that can’t match with anything.
How many chromosomes would be present in a diploid cell of a mule?
Mule: A sterile hybrid between a horse and a donkey. 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.
Can 2 mules breed?
But hinnies and mules can’t have babies of their own. They are sterile because they can’t make sperm or eggs. They have trouble making sperm or eggs because their chromosomes don’t match up well. And, to a lesser extent, because of their chromosome number.
What is a female mule called?

Why do horses mate with donkeys?
Horses and donkeys mate to produce mules, which are sterile (most of the time – there are occasional exceptions), so they do not violate that particular species definition.
Can two donkeys breed?
Yes. Specifically, when a jack donkey mates with a mare, the result is a mule. The other combination, male horse x female donkey, results in a hinny. These matings are more rare as the breeding is less likely to be successful.
