Explanation:
Detailed explanation-1: -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-2: -A fertilized egg is a zygote that results from the fusion of male and female gametes. The number of chromosome in the zygote would be double the number present in the gamete. As a result, the zygote has 48 chromosomes.
