AP BIOLOGY

Detailed explanation-1: -A cell that has two copies of each chromosome is referred to as a diploid. Hence, a Zygote is diploid.

Detailed explanation-2: -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.

Detailed explanation-3: -The correct answer to this question is (c) primary spermatocyte.

Detailed explanation-4: -Examples of diploid cells include blood cells, skin cells and muscle cells. These cells are known as somatic cells.

Detailed explanation-5: -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.
