Noun
zygote (plural zygotes)
A fertilized egg cell.
Hyponyms: homozygote, heterozygote
Because the number of chromosomes is halved during meiosis, gametes can fuse (i.e. fertilization ) to form a diploid zygote that contains two copies of each chromosome, one from each parent. Source: Internet
As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as the embryo's food supply. Source: Internet
But at some point, it splits from one zygote into two. Source: Internet
Any of the possible variants of a zygote formed from maternal and paternal chromosomes will occur with equal frequency. Source: Internet
As such, the zygote can end up with any combination of paternal or maternal chromosomes. Source: Internet
For example, citation Because identical siblings come from the same zygote, they are genetically the same. Source: Internet
