Detailed explanation-1: -The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes). The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.
Detailed explanation-2: -The most obvious difference between Haploid and Diploid is the number of chromosome sets that are found in the nucleus. Haploid cells are those that have only a single set of chromosomes while diploid cells have two sets of chromosomes.
Detailed explanation-3: -Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs. Human gametes (egg and sperm cells), however, contain a single set of chromosomes and are said to be haploid.
Detailed explanation-4: -Gamete refers to a haploid sex cell that is a sperm in males and egg (oocyte) in females. Zygote is the diploid cell that results from the fertilization between an egg and a sperm. In mammals, the sperm (male gamete) fertilizes the egg (ovum, the female gamete) and the fertilized egg is called a zygote.
