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.
Are mules multicellular?
Yes, mules are multicellular organisms.
How many chromosomes do elephants have?
elephants have 56 chromosomes
How many chromosomes are in a haploid gametes?
23 chromosomes
How many daughter chromosomes are in a human cell at anaphase?
how many chromosomes are there at the end of the anaphase? In a human
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.
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.
How many chromosomes does a donkey have?
The mule has 63 chromosomes. A donkey has 31 pairs and a horse 32 pairs so the mule or hinny inherits 31 from its donkey parent (usually the father) and 32 from its horse parent. The fact that the donkey has fewer chromosomes than the horse is thought to be the reason why hinny-breeding (where the father is the horse) is more difficult, resulting in a high rate of spontaneous abortion. If two species are to be crossed, therefore, the male should be the one with fewer chromosomes.
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.
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.
Why can't mules have offsprings?
When a female horse and a male donkey mate, you get a mule, but two mules can’t mate to create another mule because of their chromosomal makeup.A mule gets 32 horse chromosomes from its mother and 31 donkey chromosomes from its father. Mules are almost always sterile because those chromosomes don’t match up well enough to create egg or sperm cells.I say “almost always” because there have been a few extremely rare instances of female mules reproducing with a male donkey or horse. But those are so rare they’re often called “miracles,” and there have been no documented instances of a male mule fathering any offspring. So, as far as we know, two mules cannot reproduce.
How many mules are in a brace of mules?
Two mules can be a brace of mules if they are paired, haltered and equipped to work. If there are more than two animals, they will normally be termed a team.
Can you have mules as pets?
Yes. Many people ride their mules, and they do quite well in competitions.
Why mules don't have babies?
Mules are a type of HYBRID.A hybrid is a mixture of two entirely different species that aren't supposed to mate in the wild, they ARE scientifically created.A mule is the cross between a horse and a donkey.Hybrids cant mate, so that's why mules cant have babies.
