The diploid chromosome number for the body cells of a frog is 26. What would that number be after three generations if meiosis did not occur before gamete formation?

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.
