Question

Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells

Answer 1

The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

Answer 2

Answer:

The reduction of chromosomes in the gametes is necessary to make sexual reproduction possible, in which each parent contributes half of their chromosomes and in fertilization a cell with the complete amount of chromosomes is produced, the zygote.

Explanation:

The reduction of chromosomes to form gametes is done by meiosis, a reductive cell division. Sex cells or gametes are haploid cells, i.e. with half the chromosome charge, as each parent must contribute a gamete in the reproductive process.

The union of the parents' gametes is called fertilization and its product is the zygote, whose chromosome charge is complete or diploid.

For a diploid zygote to be formed, it is necessary for the sex cells or gametes to be haploid, or with half of the chromosomes of the species..
