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.
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.

In a DNA molecule, two polynucleotide strands are present. These strands are arranged in a double helix structure, with each strand consisting of a sequence of nucleotides that are complementary to each other.

How many chromosome of human (2n=46)will be found in a secondary spermatocyte
During spermatogenesis, each primary spermatocyte gives rise to four spermatozoa. This means that at the end of spermatogenesis, four functional sperm cells are produced from a single diploid germ cell.
