What is are reason’s that the mate between a horse 64 chromosomes and a donkey 62 chromosomes produces a mule 63 chromosomes that is sterile?

Asked by: Kirk Howell

What will happen if a horse with 64 and a donkey with 62 chromosomes mate?

A mule is the offspring of a male donkey (a jack) and a female horse (a mare). A horse has 64 chromosomes, and a donkey has 62. The mule ends up with 63. Mules can be either male or female, but, because of the odd number of chromosomes, they can’t reproduce.

How many chromosomes do horses donkeys and mules have?

Counting chromosomes



And, to a lesser extent, because of their chromosome number. A horse has 64 chromosomes and a donkey has 62. A mule inherits 32 horse chromosomes from mom and 31 donkey chromosomes from dad, for a total of 63 chromosomes.

How many pairs of chromosomes do a horse and mule have?

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 can a mule be born with 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. Mules are sterile because their chromosomes cannot pair up evenly, and as a result they do not produce eggs and sperm.

Can a female donkey and a male horse reproduce?

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 a horse mate with a cow?

It is well known that horses and donkeys do occasionally mate with cattle (e.g., see videos below). Such mixed matings are fairly common events on ranches and other places where these animals are likely to come into regular contact.

Are donkeys and mules the same?

Donkeys are a different species than a horse, but in the same family. They were originally bred in Egypt or Mesopotamia around 5,000 years ago. Mules, on the other hand, are a cross between a female horse and a male donkey or “jack” (hence the word “jackass”).

Can Zonkeys reproduce?

Like numerous other hybrid animals, the Zonkey itself cannot produce offspring of its own, as the cross-breeding of two different species often results in their young being sterile and unable to continue a population.

Why can’t two 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.

How many chromosomes does a donkey have?

62 chromosomes

Donkeys have 62 chromosomes and horses have 64. A mule comes from the mating of a male donkey and a female horse, and has 63 chromosomes.

Is a mule a cross between a horse and a donkey?

Mule: The result of a donkey stallion mating with a female horse. Mules tend to have the head of a donkey and the extremities of a horse. Hinny: The result of a horse stallion mating with a female donkey. Hinnies are less common than mules and there might be subtle differences in appearance.

How many chromosomes does a horse?

64

Abstract. The chromosome number of the domestic horse is 2n = 64; different races have the same complement.

Can donkeys reproduce with other donkeys?

When Donkeys Mate with Other Donkeys. Donkeys mate like several other animals in the animal kingdom do. All you need is a willing male and a willing female, and they’ll know what to do. The male donkey positions himself behind the female donkey and raises up on his hind legs to seal the deal.

What is the haploid number for donkeys?

A donkey typically has 62 chromosomes, inheriting 31 from each parent, and a zebra has 44, with 22 coming from each parent. The hybrid was found to have 53 chromosomes in which a haploid set of 22 chromosomes came from the zebra and 31 came from the donkey.

What is the diploid number for 64 chromosomes?

Given, Diploid number is 64 . Diploid number (2n)=64 . Now, haploid number (n) is half of the diploid number. ∴2n=64 .

What is the haploid number of a horse?

A Horse Sperm Cell Has A Haploid Number Of 32 Chromosomes.

How many chromosomes are in a mule diploid cell?

63

The diploid chromosome number forEquus caballus is 64, that forEquus asinus is 62, and that for the mule, 63.

How many chromosomes are in a horse gamete?

32 chromosomes

They line up in pairs during a critical period in meiosis. If we look at the gametes from a horse and a donkey, we see that a horse gamete contains 32 chromosomes and a donkey gamete contains 31 chromosomes.

How do you find the diploid number of chromosomes?

Diploid Chromosome Number



This number is abbreviated as 2n where n stands for the number of chromosomes. For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes (22 sets of two autosomal or non-sex chromosomes and one set of two sex chromosomes).

How do you find the diploid and haploid number of chromosomes?

In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.

How do you calculate the haploid number?

If you'll recall is you multiply 3 by n. And you multiply this side by 3 too.

How do you calculate chromosomes?

It is very simple to count number of DNA molecules or chromosome during different stages of cell cycle. Rule of thumb: The number of chromosome = count the number of functional centromere. The number of DNA molecule= count the number of chromatids.

What is the diploid 2n and haploid n number of chromosomes?

Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).

What does 2n 4 mean in mitosis?

In this example, a diploid body cell contains 2n = 4 chromosomes, 2 from mom and two from dad. In humans, 2n = 46, and n = 23.

What’s haploid and diploid?

Haploid refers to the presence of a single set of chromosomes in an organism’s cells. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.
