Embryo undergoes mitotic divisions throughout its development. Since the number of cells increases with each mitotic division, it is important all of them to persist in normal cell division. That way the embryo development will end successfully when a baby is born. But, if all cells of the embryo fail to go through S phase, the DNA will not replicate. As mentioned, DNA replication occurs in the S phase of mitosis. <span>A cell cycle will be interrupted and the mitotic divisions will stop. Consequently, the embryo will die.</span>

microbes for absorption of nutrients. a patient with celiac disease lacks the cilia necessary to absorb nutrients, located in the small intestine; resulting in starvation, vomiting,weight loss..until death, usually by the age of 30 or b4.
Answer:
The number will be 208 after third generation.
Explanation:
Meiosis is a type of cell division that occur in eukarytotic reproductive cells and it divide diploid chromosomes into haploid chromosomes. Nuclear division happen twice in meiosis.
The diploid number for the chromosome number of frog is 26. There fore if there is no occurrence of meiosis before gametes are formed there won't be any reduction in the number of chromosomes. The gametes will be diploid and it will have the same number of chromosomes as the parent cell which is 26. Zygote will be formed after the egg fuses with the sperm.
The first generation will be 26 + 26= 52.
Second generation is 52 + 52=
104.
Third generation is 104 + 104 = 208.
The chromosome number will be doubling from generation to generation if meiosis did not occur. After theirs generation it will be 208.
