Answer:
Meiosis is a reduction division of diploid cells.(2n) Chromosomes numbers are reduced with each successive division stages of meiosis 1 and 2, to haploid(n).
Cats have 38 diploid somatic (body)chromosome (2n) in the somatic cells and are reduced to 19 new varied haploid cells (n) of chromosomes in the gametes.
In cats, as in other mammals, during spermatogenesis in (seminiferous tublule of testis) and oegensis(in the ovaries);<u>meiotic reduction division</u> reduced the diploid somatic chromosomes to haploid chromosomes in sex gametes.
Therefore 38 chromosomes will be in the somatic chromosomes, while the sex gametes, with double-helical molecules of DNA, at the end of meiosis II will have 19 chromosomes, half of the somatic chromosomes.
