If all your cells come from the original zygote that formed you, why aren’t all of them identical to each other?
A. because the zygote divides, and at a certain stage, all cells attain their own specific structure and function through a process called differentiation
B. because the zygote divides, and while dividing, the different parts of the zygote acquire new genetic information, which makes them different and nonidentical to each other
