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.

If a diploid cell containing 28 chromosomes undergoes meiosis how many chromosomes will each daughter cell have?
56 chromosomes
What parts of your body does meiosis occur?
it occurs in the gametes, the sex cells. where mitosis occurs in all other cells that have two halves of chromosomes, meiosis occurs in cells which only have one half of the chromosomes.
How many chromosomes will be found in each daughter cell after mitosis?
46 chromosomes will be found in a human daughter cell after mitosis, 23 chromosomes will be found after meiosis.
Do the X and Y chromosomes cross over at male meiosis?
No, X and Y chromosomes don't cross over during male meiosis. Otherwise there would be risk of male specific genes occurring in XX individuals.
What are the final products of meiosis in male?
2 haploid gametes, each with 23 chromosomes
When does duplication of chromosomes occur?
when does the duplication of chromosomes occur?
How many chromosomes are present when meiosis starts?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
How many chromosomes would a cell have during metaphase 1 of meiosis if it has 12 chromosomes during interphase?
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
How many chromosomes are present when meiosis is started?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
Are chromosomes single or double in meiosi?
The chromosomes are double (diploid) at the beginning of meiosis. By the end of meiosis I, the chromosomes are single (haploid).
Explaining why the process of mitosis and meiosis are both?
mitosis is the duplicate of chromosomes and meiosis is the reducing of chromosomes.
Chromosomes are duplicated?
The chromosomes duplicate themselves in Meiosis 1, however they don't duplicate in Meiosis 2.
What is the end result difference between mitosis and meiosis?
Mitosis = doubling of chromosomes. Meiosis = halving of chromosomes.
What happens to chromosomes for meiosis to start?
The chromosomes divide.
How do chromosomes separate?
meiosis
Do chromosomes pair up in meiosis?
to complete the meiosis cycle
Does meiosis double the parental chromosomes number?
Meiosis 1
