Question

What is Zygote?

Answer 1

A zygote is a eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete and contains all of the genetic information necessary to form a new individual. In multicellular organisms, the zygote is the earliest developmental stage. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo. The cells from each parent that combine to form the zygote are called gametes. In humans, the male gamete is called sperm, and the female gamete is called an egg. When the gametes join they form a cell called a zygote. In plants, the fusion of female ovule and the male sperm develops a zygote.
