Detailed explanation-1: -Therefore, if the meiocyte of an organism has 24 chromosomes, then the gamete will have 12 chromosomes.

Detailed explanation-2: -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.

Detailed explanation-3: -Egg and sperm cells have just 23 chromosomes each. That’s half as many chromosomes as regular cells. Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote.

Detailed explanation-4: -So, haploid cells contain half the number of chromosomes of somatic cells. Therefore, if we divide the 46 chromosomes we know exist in diploid somatic cells by two, we get 23. This means each gamete contains 23 chromosomes. In sexual reproduction, during fertilization, an egg and a sperm cell join to form a zygote.

Detailed explanation-5: -Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state. Human gametes have 23 chromosomes or one complete set of chromosomes. This is the n, or haploid, state.
