What is a zygote and how is it formed
Leokris [45]

Answer:

A zygote is a fertilized ovum. The germ cells undergo meiosis to reach a haploid state (n) as part of spermatogenesis and oogenesis. The sperm and the unfertilized ovum reinstates a chromosome set in zygote in a diploid state (2n).

After fusing with the sperm, the second stage of meiosis takes place for separation of chromatids. Post-fertilization, mitosis of the zygote is initiated which develops into a mature offspring exhibiting characteristics of its parent.

Explanation:

The zygote stage development occurs in the first week of fertilization. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to form an individual.
