The primary Spermatocyte has a chromosome number of 46, the secondary Spermatocyte has 23.
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.
A pig has 38 pairs of chromosomes, for a total of 76 chromosomes.
i believe its 2
8 chromosomes
38 chromosomes in one cell.
If there are 13 homologues in a primary spermatocyte, that means the sperm will contain half that number since the number of chromosomes is halved during meiosis. Therefore, a sperm from that primary spermatocyte would contain 6.5 chromosomes, which is not a practical biological number because chromosomes cannot be divided in half.
There are 13 pairs of homologous chromosomes in a primary spermatocyte, which means there are 26 chromosomes. During meiosis, the primary spermatocyte undergoes two divisions, resulting in four spermatids with 13 chromosomes each. Therefore, a sperm cell would also have 13 chromosomes.
There are only two strands within the DNA that is present in a primary spermatocyte. There are many double stranded breakage DNAs withing the spermatocyte.

One primary spermatocyte undergoes meiosis to produce four sperm cells.
Each primary spermatocyte undergoes meiosis to produce four haploid spermatids.
4 spermatids are formed from one primary spermatocyte.
A spermatid contains 23 chromosomes, which are the result of meiosis dividing the original diploid germ cell's 46 chromosomes in half. This reduction in chromosome number ensures that when the spermatid fuses with an egg during fertilization, the resulting zygote will have the correct number of chromosomes.
A cell of the testes, called a spermatocyte, has 46 chromosomes in humans. This includes 23 pairs of chromosomes, one set inherited from each parent. During the process of meiosis, the number of chromosomes is halved to 23 to create sperm cells.
A primary spermatocyte with 46 chromosomes will undergo meiosis and yield four spermatids with 23 chromosomes. A primary spermatocyte undergoes meiosis I two haploid secondary spermatocytes are produced.

The primary spermatocyte is diploid(2n) and after first meiotic division it will produce 2 haploid(n) secondary spermatocyte and these in turn after second meiotic division will produce 2 more haploid secondary spermatocyte. Therefore by the end of Meiosis one will have 4 haploid secondary spermatocyte or spermatids.
