Solution

Dear Student,

Zygote is the diploid cell formed by the fusion of male and female gametes during fertilization in sexual reproduction. Zygote is the first stage in the development process of an organism and it contains all the genetic information essential for the growth of the new organism.

Number of chromosomes in meiocyte = 24
Number of chromosomes in gametes = 12
Number of chromosomes in the zygote = 24
Number of chromosomes in the embryo = 24
