Explanation:
Detailed explanation-1: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
Detailed explanation-2: -Gametes are produced through a type of cell division called meiosis and hence are haploid in nature. They carry only one copy of each chromosome and therefore contain only 23 chromosomes.
Detailed explanation-3: -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.
