Explanation:
Detailed explanation-1: -In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes.
Detailed explanation-2: -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-3: -After meiosis II, each gamete will have half the chromosome numbers as that of the somatic cells i.e., total 4 chromosomes.
