Will last until the developing cells have attached to the uterine wall, about 8- Because the zygote has received half a genome from each gamete, it now has a full genetic load which makes it diploid. Diploid: cell containing both sets of chromosomes: during germinal period they zygotic cell divides multiple times, creating numerous identical copies that hold together in a spherical shape. Divisions occur through cleavage: division of cells in the early embryo to form blastomeres. After a few instances of cleavage, the resulting spherical mass of cells is known as morula. Excluding gametes, every cell in your body contains exactly the same dna: dna is blueprint cells use to produce the materials needed to specialize its function and operate with the other cells in your body. Epigenetic modification is the reason for differences among different cells in.
