Detailed explanation-1: -The number of chromosomes in the gamete is haploid and human gametes contain 23 chromosomes. As zygote is from the fusion of two gametes, the chromosome number is diploid and is double of that in gamete and thus 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.
Detailed explanation-3: -Each egg cell or sperm contains 23 chromosome whereas a normal cell has 46 chromosomes.
Detailed explanation-4: -Zygote is formed due to the fusion of male and female gametes. Gametes are haploid cells. Thus fusion of two haploid cells results in the formation of a diploid cell. Therefore zygote is a diploid cell with 46 chromosomes.
Detailed explanation-5: -Sperm is a male reproductive cell. The sperm is a haploid cell means it contains half the number of chromosome of the parent cell. A human contains 46 chromosomes in it. Thus, mature sperm contains 23 chromosomes.
