Detailed explanation-1: -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: -The chromosome complement of Anopheles mosquitoes consists of three pairs of chromosomes: two sex chromosomes (XX in females and XY in males) and two pairs of submetacentric autosomes.

Detailed explanation-3: -When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of gene shuffling while the cells are dividing.

Detailed explanation-4: -Abstract.-Chromosome number and morphology in mosquitoes is remarkably uniform: virtually all mosquitoes have a diploid chromosome number of six (2N = 6), and their chromosomes are invariably metacentric or submetacentric.

Detailed explanation-5: -If the sperm and egg cells of a butterfly have six chromosomes, 12 chromosomes will be there in the maggot larvae. This is because maggot larvae forms due to the fusion of egg and sperm cells. Since egg contains 6 and sperm cells contains 6 chromosomes, maggot larvae will get both sperm cell and egg cell chromosomes.
