NEET BIOLOGY

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: -Human fertilization and development Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg.

Detailed explanation-3: -Types of sexual life cycles Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.

Detailed explanation-4: -A cell that has two copies of each chromosome is referred to as a diploid. Hence, a Zygote is diploid. Each chromosome is present in two homologous, or comparable, copies in almost all human body cells. Due to the presence of both of its parents’ genes, the zygote is diploid (carrying two sets of chromosomes).

Detailed explanation-5: -Diploid zygote is formed by the fusion of male and female gamete.
