Why is there no duplication of the DNA between meiosis I and meiosis ii ?

Question

It is one of these choices to produce geentically identical daughter cells or to increase genetic variability, to reduce the chromomosome number to haploid in the resulting daughter cells or the chromosomes duplicate twice during meiosis I.

Answer 1

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

The whole point of meiosis is to create a gamete cell (sperm/egg) with half the number of chromosomes as regular body cells.

Answer 2

To reduce the chromosome number.

Here is why:
Meiosis I is basically the same as mitosis. However, meiosis II is an extra division of the cell without chromosome replication. The reason why there is that extra cell division is to divide the chromosomes in half. Normally, you have 46 chromosomes in your cells. Meiosis creates sperm and eggs that have 23 chromosomes each. That way, when sperm and egg meet in fertilization, 23 +23= 46. This ensures that babies have the right number of chromosomes.
