Question

Discuss the development of zygote in human beings

Answer 1

 genetic material of the sperm and egg then combine to form a single cell called a zygote and the germinal stage of prenatal development commences. ... During this stage, the zygote begins to divide, in a process called cleavage. A blastocyst is then formed and implanted in the uterus.

Answer 2

Answer:

Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells. The zygote represents the first stage in the development of a genetically unique organism. 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.
