Mules and hinnies have 63 chromosomes, a mixture of the horse’s 64 and the donkey’s 62. The different structure and number usually prevents the chromosomes from pairing up properly and creating successful embryos, rendering most mules infertile.
Why mules are generally sterile?
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. A mule gets 32 horse chromosomes from mom and 31 donkey chromosomes from dad for a total of 63 chromosomes.
Why are mules sterile in nature 11?
Mule gets one set of chromosomes (32) from male parent, horse and one set of chromosomes (31) from female parent, donkey. These two sets of chromosomes do not match with each other and cannot produce gametes by meiosis. Hence mule is sterile in nature.
Can mules reproduce naturally?
Mules can be either male or female, but, because of the odd number of chromosomes, they can’t reproduce.
Why can’t mules reproduce?
In the mule, the horse and the donkey each had 64 and 62 chromosomes, respectively. This uneven shuffling of the deck results in the mule getting 63 chromosomes. To reproduce requires an even number of chromosomes, so mules can’t have babies.
Why can’t ligers reproduce?
In short, hybrid animals are infertile because they don’t have viable sex cells, meaning they can’t produce sperm or eggs. This is the case because the chromosomes from their different species parents don’t match up.
Why mule is sterile in nature Brainly?
The offspring has an odd number of chromosomes which nearly always means that they are sterile and can’t reproduce. The chromosomes from pairing up properly and creating successful embryos, rendering most mules infertile.

What is the difference between a mule and a jackass?
A mule is a cross between a horse and donkey. However, it’s a cross between a mare (a female horse) and a jack (a male donkey, thus the name jackass).
Are mules human made?
Mules are hybrid animals resulting from the crossbreeding of a horse mother and a donkey father. While it’s possible for horses and donkeys to breed in the wild, the vast majority of mules have been created by humans through selective breeding.
Do mules try to mate?
Most documented cases of mules/hinnies being fertile have been in the female mule (molly/mare mule). … Also, keep in mind it’s likely that more mules may be fertile, but we commonly do not attempt to breed mules. Mules and hinnies that have foaled in the past were bred to jacks (male donkeys).
Can a zebra breed with a donkey?
These zebra-donkey hybrids are very rare. In South Africa, they occur where zebras and donkeys are found in proximity to each other. Like mules and hinnies, however, they are generally genetically unable to breed, due to an odd number of chromosomes disrupting meiosis.
Can a horse mate with a mule?
But combined with the dissimilarities in the horse-donkey chromosomes, the end result is usually — but not always — sterile offspring. While there are no recorded cases of fertile mule stallions, there have been a few dozen cases of mule mares giving birth after mating with a horse or donkey.
