Describe How a One-Celled Zygote Develops into a Baby with 5

Question

Examlex · Accepted Answer

The Answer is Within hours after conception, a zygote begins duplication and division. First the 23 pairs of chromosomes carrying all the genes duplicate, forming two complete sets of the genome. These two sets move toward opposite sides of the zygote, and the single cell splits down the center, forming two cells. Each of these cells contains the original genetic code.
These two cells duplicate and divide again, becoming four, which duplicate and divide, becoming eight, and so on. At approximately the eight-cell stage, although duplication and division continue, differentiation begins. During differentiation, cells specialize, becoming heart, ear, or liver cells, etc.
