primary spermatocyte a diploid cell that has derived from a spermatogonium and can subsequently begin meiosis and divide into two haploid secondary spermatocytes.
Secondary spermatocyte
How many chromosome of human (2n=46)will be found in a secondary spermatocyte
The five steps of spermatogenesis are: 1) Spermatogonium division, 2) Primary spermatocyte division, 3) Secondary spermatocyte division, 4) Spermatid formation, and 5) Spermatozoa maturation.
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.

Secondary spermatocyte
How many chromosome of human (2n=46)will be found in a secondary spermatocyte
Secondary spermatocytes are haploid because they result from the first meiotic division in male germ cells, which reduces the chromosome number by half. This process includes homologous chromosomes separating, leading to the formation of haploid daughter cells.
The five steps of spermatogenesis are: 1) Spermatogonium division, 2) Primary spermatocyte division, 3) Secondary spermatocyte division, 4) Spermatid formation, and 5) Spermatozoa maturation.
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
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.
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.
4 spermatids are formed from one primary spermatocyte.
