How meiosis reduces the number of chromosomes by half?

Answer 1

First of all you get a haploid number of chromosomes which is 23 from your mom and 23 from your dad which creates a diploid cell, which is the first body cell of a human, then the cell divides once and there is DNA replication which forms 2 cells then it divides again but DNA is not replicated and you get 4 haploid cells which is half. I KNOW THIS CAUSE I LEARNED IT A FEW WEEKS AGO IN SCIENCE 9!! HOPE I HELPED... =)

Answer 2

Between meiosis I and meiosis II there is no DNA replication, so the process of division in meiosis II results in cells with half the number of chromosomes as the mother cell.

Meiosis in itself means cutting chromosomes in half since it is the process of creating gametes. During meiosis 1 the cell is reformed into two cells with half the number of a normal cell...23 rather than 46 for humans. During meiosis 2 the 2 new cells separate into two more cells with 23 chromosomes. The reason for the halving of the chromosomes is to ensure diversity of the population and to enable two gametes, one from each parent to merge and create a new being.

There are 4 phases prophase I, metaphase I, anaphase I, and telophase I in the first meiotic division and 4 phases in second meiotic division prophase ll, metaphase ll, anaphase ll, and telophase ll where the chromosomes are mixed up and paired uniquely to form gametes. After second meiosis 4 gametes are the product.

Answer 3

Meiosis involves two rounds of cell division (meiosis I and meiosis II), resulting in the formation of four daughter cells with half the number of chromosomes as the parent cell. During meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over. This reduces the chromosome number by half in the resulting daughter cells.

Answer 4

Meiosis reduces the number of chromosomes to half the number in the parent cell. It does this by dividing the DNA in half.

Answer 5

DNA replicates in meiosis I, but not in meiosis II. So, there is one DNA replication followed by two divisions.

Answer 6

meiosis 1 is normal mitosis, but during meiosis 2 the chromosomes don't duplicate,so at the end of the process there are half the number of chromosomes as the parent cell

Answer 7

Replication does not occur.
