Multiple choice

Why DNA does not duplicate between meiosis I and meiosis II?

  1. To reduce the chromosome number to haploid in the resulting daughter cells

  2. To produce genetically identical daughter cells

  3. To increase genetic variability

  4. The chromosomes already duplicated twice during meiosis I.

A Correct answer
Explanation

In the process of meiosis, four haploid daughter cells are formed. In humans, cells that go through meiosis are the sperms and egg cells. The reason why DNA does not duplicate between meiosis I and meiosis II is because only half the number of chromosomes is necessary in a sperm or egg cell. That's why, when a sperm fertilizes an egg, each cell has half the number of chromosomes necessary to create an organism, so together, they have the correct amount of chromosomes.
