  1. there are 13 individual ones=haploid number(n)


  2. The primary spermatocytes will have 13 pairs of homologous chromosomes.

    The secondary spermatocytes will have 13 chromosomes (each with 2 sister chromatids).

    Spermatids and spermatozoa (sperm) will have 13 chromosomes (each with 1 chromatid).

  3. 13 individual ones = the haploid number (n).
