Detailed explanation-1: -Each egg cell or sperm contains 23 chromosome whereas a normal cell has 46 chromosomes.

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. For each chromosome pair, one homologous chromosome came from each parent.

Detailed explanation-3: -Answer and Explanation: It is important that human sperms and eggs have only 23 chromosomes because this way when fertilization occurs, it will form one full diploid cell, which will then divide via mitosis to form a full organism.

Detailed explanation-4: -[HUMAN KARYOTYPE] Humans have 23 pairs of homologous chromosomes. How many of these chromosomes will be found in an egg cell? All 46 chromosomes.

Detailed explanation-5: -The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half-from 46 to 23-to form sperm and egg cells.
