Each primary spermatocyte undergoes meiosis to produce four haploid spermatids.
4 spermatids are formed from one primary spermatocyte.
Spermatogenesis- takes place in the seminiferous tubule of the testesIt is the form of gametogenesis taking place in males and utilises the two forms of nuclear division to produce a haploid gamete.A cell from the germinal epithelium (2n) divides by mitosis to form the spermatagonia (2n), which then develops into the primary spermatocyte (2n). The primary spermatocyte divides by meiosis 1 to form the secondary spermatocyte (n), which divides by meiosis 2 to become the spermatid (n). This spermatid develops and matures in the epididymis to form the final spermatazoon (or just sperm)Germinal epithelium --> Spermatagonia --> Primary spermatocyte --> Secondary spermatocyte --> Spermatid --> Spermatazoon
When you duplicate your 46 chromosomes, you will have 92 chromatids.
In a cell with 6 chromosomes, each consisting of 2 chromatids, there are a total of 12 chromatids present.
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.
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.

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.
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.

primary spermatocyte a diploid cell that has derived from a spermatogonium and can subsequently begin meiosis and divide into two haploid secondary spermatocytes.

The five steps of spermatogenesis are: 1) Spermatogonium division, 2) Primary spermatocyte division, 3) Secondary spermatocyte division, 4) Spermatid formation, and 5) Spermatozoa maturation.
