Detailed explanation-1: -2n = 16, it means n = 8. The haploid number of chromosomes is 8. The sperm and egg cells have a haploid number of chromosomes. Thus, it will have 8 chromosomes in their cell.
Detailed explanation-2: -This division is an important event since after fertilisation haploid chromosomes from each gamete (male and female) fuse to retain the diploid state in the zygote. Diploid means two sets of chromosome and haploid is one set. Since here the diploid set is 16 thus one set will be half it, i.e, 8.
Detailed explanation-3: -So the final answer is 8 chromosomes.
Detailed explanation-4: -So, if the parent cell has 16 chromosomes, after meiotic division it will get reduced to half and thus, the daughter cells will have 8 chromosomes.
Detailed explanation-5: -The gametes such as sperms and eggs are typically the haploid cells, while the somatic cells and the zygote have a diploid number. If the organism’s haploid chromosome number is 16, then precisely double the haploid number will be the diploid number, 32.
