Embryonic Period. the embryonic period is weeks 3-8 of development; the three germ layers- ectoderm, mesoderm, and endoderm- form the tissues and main organ systems and the body becomes recognizably human.
Somatic mutations that happen in a single cell early in embryonic development can lead to a situation called mosaicism. These genetic changes are not present in a parentâs egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells.As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not.n some cases, the mutation occurs in a personâs egg or sperm cell but is not present in any of the personâs other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite.
