Question

What would happen if gametes are formed by mitotic divisions?

Image: A diagram showing gametes formed by mitosis keeping the full chromosome number, so that after fertilisation the chromosome number would double in each generation instead of staying constant.

Answer
The chromosome number would keep doubling.

Explanation

  • Mitosis keeps the full chromosome number.
  • So gametes would have the full number, not half.
  • At fertilisation, two full sets would combine.
  • So the chromosome number would double each generation.
Meiosis halves chromosomes so the number stays constant.
Gametes by Mitosis? Gametes formed by mitosis Chromosome number not halved Doubles every generation
