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.
As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as the embryo's food supply.
But at some point, it splits from one zygote into two.
Any of the possible variants of a zygote formed from maternal and paternal chromosomes will occur with equal frequency.
As such, the zygote can end up with any combination of paternal or maternal chromosomes.
For example, citation Because identical siblings come from the same zygote, they are genetically the same.
