Detailed explanation-1: -Fertilization. The process in sexual reproduction in which a female gamete and male gamete fuse to form a new cell. Zygote. Cell resulting from fertilization. Diploid (2n)
Detailed explanation-2: -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-3: -Definition. Haploid refers to the presence of a single set of chromosomes in an organism’s cells. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.
Detailed explanation-4: -fertilization, Reproductive process in which a male sex cell (sperm) unites with a female sex cell (egg). During the process, the chromosomes of the egg and sperm will merge to form a zygote, which will divide to form an embryo.
