Male diploid cell (2n, 46 complete set of chromosomes) > meiosis > produces sperm, half set of chromosomes/ haploid (n = 23)
Female diploid cell (2n) > meiosis > produces egg, haploid (n)
Fertilization -
egg cell + sperm cell ( n+n = 2n 23+23 = 46 ) >
zygote ( 1/2 male and 1/2 female chromosomes) >
The zygote doubles (mitosis) over and over again till it forms the embryo
Fertilization > Zygote > Embryo
