Verified step by step guidance1
Understand that a zygote is formed when a sperm cell and an egg cell unite during fertilization.
Recall that human somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent.
Each human gamete (sperm or egg) is haploid, containing 23 chromosomes.
During fertilization, the haploid sperm and haploid egg combine to form a diploid zygote.
Calculate the total number of chromosomes in the zygote by adding the 23 chromosomes from the sperm and the 23 chromosomes from the egg, resulting in a total of 46 chromosomes.
