Are mules the result of a horse and donkey mating?
Mules are usually sterile. Once in a (great) while a female mule proves to be fertile when mated with a horse or donkey, though this is extremely rare. There are no known cases of fertile male mules. Horses and donkeys have different numbers of chromosomes, so mules wind up with an odd number of chromosomes (32 from one parent and 31 from the other). This messes up the genetic machinery that makes sperm and egg cells. It's sort of like making copies on a bad copy machine: you might be able to read a copy of a clean original, but a copy of that copy is usually illegible.

What happens in Chromosomes?
Well nothing exactly happens in chromosomes but they contain DNA and heredity that makes you you. By the way, they are also called chromatids. P.S I'm in 7th grade so yea
What happens in a mules chromosomes when it's sterile?
Mules are sterile due to their unique chromosome composition, resulting from the crossbreeding of a horse (64 chromosomes) and a donkey (62 chromosomes), resulting in 63 chromosomes. This odd number prevents proper pairing during meiosis, the process of forming gametes. As a result, mules cannot produce functional sperm or eggs, leading to sterility.
How many chromosomes do mules have?
Mules typically have 63 chromosomes, which is a combination of 32 chromosomes from horses and 31 chromosomes from donkeys. This uneven number of chromosomes in mules makes them sterile because they are unable to produce viable gametes during reproduction.
Are mules considered a species?
Donkeys? No. They are sterile Mules do not breed. They have 1 too many chromosomes wich makes them infertile.
Why can't a mule reproduce?
Mules are hybrid offspring of a male donkey (Jack) and a female horse (mare) Mules have 63 chromosomes, this odd number causes the vast majority to be born sterile. however it should be noted that female mules can reproduce, but this is very uncommon.
An ass has 64 chromosomes and a mule is a horseass hybrid Descibe why there will be a difficulty in meiosis in mules?
The answer is more complicated than chromosome number. Offspring of a cross between Przewalski's horse (66 chromosomes) and the domestic horse (64 chromosomes) are trisomic (2n+1) just like mules, mollies and hinnys, yet they are not sterile. The problem is that while horses and donkeys share much of the same genetic information, it is structured differently. Testicular meiosis is arrested in Mules and hinny stallions at the primary spermatocyte stage because of incompatibility of synaptal pairing between paternal and maternal chromosomes.
What prevents mules from having offspring?
Mules are infertile because the horse and the donkey do not have the same number of chromosomes. Horses have 32 pairs of chromosomes while the donkey only has 31 pairs. The offspring will also show both characteristics of both different specie.
How much chromosomes number of sterile animal?
If referring to Mules, they have 63 chromosomes. They receive 32 chromosomes from the horse and 31 from the donkey, resulting in infertility due to the uneven number of chromosome pairs.
What is the diploid number of a mule and why is it that they are infertile?
The diploid number of a mule is 63. Mules have an odd number of chromosomes (63) - which means that the chromosomes do not pair off properly. This causes problems with meiosis, which is the process that creates the gametes (sex cells) that will be involved in sexual reproduction. This is why almost all mules are infertile. Mules are the result of a cross between two species. By definition, the offspring from two different species cannot be fertile. However, there are a few very rare cases of a female mule having a viable offspring.

Why donkeys are infertile?
The offspring of a horse and a donkey is called a mule. The mules are usually infertile because they have 63 chromosomes.
Is a mule a tetrad?
No a mule is not a tetrad, this is due to the fact that the mule has 63 chromosomes. Mules are a hybrid between the horse and the donkey, and are unable to reproduce due to the uneven number of chromosomes.
