NEET BIOLOGY

Detailed explanation-1: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining-a process called implantation.

Detailed explanation-2: -A zygote is the first diploid cell that is formed by the fusion of male and female gametes resulting in the formation of an embryo. The zygote stage development occurs in the first week of fertilization.

Detailed explanation-3: -Fertilization results in the formation of zygote. The male gamete cell (sperm) and female gamete cell (egg) fuse together to form a zygote. Zygote divides repeatedly to give rise to balls of cells.
