Detailed explanation-1: -The somatic cells are diploid that contains divides through mitosis and have two copies of chromosomes. Mosquito contains six homologous chromosomes in its somatic cells. The division of germ cells will result in gametes formation containing only one copy of the chromosomes, giving rise to 3 chromosomes.

Detailed explanation-2: -1) The diploid cell has 6 chromosomes. 2) During Meiosis, the two sets of chromosomes line up on the Metaphase I plate and exchange genetic material. 3) This process results in 24 new chromosomes.

Detailed explanation-3: -A mosquito cell has 6 chromosomes at the start of mitosis, these chromosomes are double-stranded. At the end of mitosis, this cell will have divided into two daughter cells that also contain 6 chromosomes each. Therefore, each daughter cell will be given 6 chromosomes (single-stranded).

Detailed explanation-4: -If a cell containing 6 chromosomes undergoes mitosis cell division, the resultant two daughter cells will also contain 6 chromosomes each. During the S-phase of the mitosis, the genetic material, DNA, is replicated, and each daughter cells receives a copy of all the chromosomes in the parental cell.

Detailed explanation-5: -For a species containing a haploid number of n chromosomes, the possible number of combinations of maternal and paternal chromosomes for the gametes are given by the relation 2n . The different combinations found for a species with a haploid number of 6 chromosomes are equal to 64.
