when does the duplication of chromosomes occur?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.

The chromosomes are double (diploid) at the beginning of meiosis. By the end of meiosis I, the chromosomes are single (haploid).
No, meiosis does not result in the doubling of chromosomes. Instead, it reduces the number of chromosomes in a cell by half.
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
In humans meiosis produces 23 chromosomes. The human body cell has 46 chromosomes When meiosis occurs 1/2 of the body cells go into the haploid cell produced
The products of meiosis 1 are two haploid daughter cells with duplicated chromosomes, while the products of meiosis 2 are four haploid daughter cells with unduplicated chromosomes. Meiosis 1 separates homologous chromosomes, while meiosis 2 separates sister chromatids.
The chromosomes divide.
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
At the end of meiosis I, the chromosomes are duplicated (sister chromatids) and homologous chromosomes separate. At the end of meiosis II, the sister chromatids separate, resulting in four haploid daughter cells each with a single set of chromosomes. Meiosis II is similar to mitosis in terms of chromosome behavior as the sister chromatids separate.
