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 a fertilized ovum. After fertilization zygote undergoes rapid mitotic division. The zygote then travels down to the fallopian tube to the uterus. As it travels, its cell rapidly divides and it becomes a blastocyst.

Detailed explanation-3: -During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus. This results in the formation of a fertilized egg or zygote.

Detailed explanation-4: -A zygote is an egg that has been fertilized by sperm, and which could develop into an embryo.

Detailed explanation-5: -A single sperm and the mother’s egg cell meet in the fallopian tube. When the single sperm enters the egg, conception occurs. The combined sperm and egg is called a zygote. The zygote contains all of the genetic information (DNA) needed to become a baby.
