If a cat normally has 38 chromosomes in its somatic (body) cells, how many chromosomes will be in its gametes? a. 76 b. none of
Keith_Richards [23]

Each gamete has half the number of chromosomes of the somatic cell. Hence, cats' gametes will have <u>19 chromosomes.</u> Option C.

<h3>What are the type of cells in the organism?</h3>

The types of cells in the organism are somatic and germ cells.

Both the somatic and germ cells go through mitosis producing two daughter cells with the<u> same </u><u>genetic dotation</u>.

Somatic cells are any cell in the body except sperm and egg cells. They are diploid, meaning they contain two chromosome sets, each one inherited from each parent.

Germ cells are diploid reproductive cells. They suffer mitosis to form more sexual cells, and a few suffer meiosis to produce haploid gametes. Each germ cell produces 4 haploid gametes.

Each gamete has half the number of chromosomes of the somatic cell. Hence, cats' gametes will have <u>19 chromosomes.</u> Option C.
