They are the most common type of reef system on the planet. They are similar to Barrier reefs which also grow parallel to coastlines, but barrier systems are separated by deeper and much wider lagoons.</span>

Domestic cats have 38 chromosomes in their diploid cells. If a diploid cat cell enters meiosis, how many chromosomes and double-
sdas [7]

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.
