Question

explain zygote formation in humans.?​

Answer 1

Explanation:

Life... while you may have seen the popular Discovery series on the topic, or you may have pondered the meaning of life, have you ever thought about where it begins or about the events that lead up to the birth of a baby? What exactly is the miracle of life?

Well, it all starts with two small cells called gametes: a mature sperm (from the male) and a mature egg, or oocyte (from the female). In humans, each of these gametes has 23 chromosomes - that's half the amount of DNA required for development, so these cells are called haploid cells.

The fusion of these two cells is called fertilization and it produces a diploid cell with 46 chromosomes - twice the amount found in each gamete. The fertilized egg is now called a zygote and has just the right amount of DNA needed for normal human development.

Sounds simple, right? Well, like many things in life, it's not quite as simple as it looks.

While the process of fertilization isn't completely understood by scientists, we do know a fair bit about what happens. In this lesson, we will cover some of the basics of that fated meeting between egg and sperm.

In human beings, fertilization takes place inside the female body.

It is the fusion of male and female gametes, that is sperm and ovem, it is the first stage in process of reproduction during fertilization, the nuclei of egg and sperm fuse together to form a single nuclei. This results in formation fertilized egg or zygote.
