How can donkeys and horses breed if they are different species?
Mating can income between any two related or unrelated species. In other species fertilization doesn’t take place, but in a cross of male horse with a female donkey fertilization also takes place in spite of different genomes, but the offspring’s produced are sterile. This is an exceptional case of its own type.
Why are donkeys and horses not the same species if they can produce offspring?
Both the offspring (hybrid offspring) produced by donkeys and horses are infertile, sterile, cannot have its own offspring and both have 31 pairs of chromosomes each. Because of this, both horses and donkeys are considered as a separate species.
Why can a horse and donkey interbreed?
In other words, the extra genes on the horse chromosome do not cause problems for the every day life of a mule. So mules are sterile because horse and donkey chromosomes are just too different. But they are alive because horse and donkey chromosomes are similar enough to mate.
How many chromosomes does a donkey have horse?
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.
Can two donkeys mate?
When Donkeys Mate with Other Donkeys What is this? The common myth that donkeys can’t reproduce is just that, a myth. However, when partnered with certain other species, donkeys join forces to create animals that cannot reproduce.
Can horses breed with each other?
Inbreeding is the mating of horses of the same breed which are more closely related than the average of the breed.
Can donkeys reproduce with other donkeys?
They will have the instinct to mate with other mules, donkeys, horses, and other animals, but they can’t produce offspring.
Do horses and donkeys belong to the same species?
All you need to know is that animals like horses, donkeys and mules are entirely separate species. However, they have all evolved from the same family called equidae. These species all belong to a sub-family of animals called equus.
How genetically similar are horses and donkeys?
The horse and donkey genome are more alike than different The genome has 18,984 protein-coding genes – just a thousand or so fewer genes than our own genomes – comprising about 1.3 percent of the total sequence, also a little like us.
Do donkeys and horses mate?
A hinny is a domestic equine hybrid that is the offspring of a male horse (a stallion) and a female donkey (a jenny). It is the reciprocal cross to the more common mule, which is the product of a male donkey (a jack) and a female horse (a mare)….

Can male and female donkeys mate?
A male donkey can mate with a female horse to make a mule. They’re great for use as pack animals. Owners get a good mix of strength and stamina (from the donkey), as well as size and speed (from the horse).
Why donkeys and horses are not homologous?
Even though horses and donkeys have relatively similar number of chromosomes, a large number of those chromosomes have gone through various inversions which have altered the genes found on specific chromosomes, meaning that they are not longer truly homologous.
Why do donkeys have trouble making sperm?
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. (A horse has 64 chromosomes and a donkey has 62).
Can a female horse and a male donkey have babies?
A female horse and a male donkey have a mule. 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.
Why do mules have more chromosomes than horses?
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. (A horse has 64 chromosomes and a donkey has 62).
