The chromosome number is halved during the first stage of meiosis, known as meiosis I.
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.

To determine if a sperm cell is in meiosis I or meiosis II, you can look at the chromosome number and structure. In meiosis I, homologous chromosomes are separated, resulting in cells with a diploid (2n) chromosome number, where each chromosome still consists of two sister chromatids. In contrast, during meiosis II, sister chromatids are separated, resulting in haploid (n) cells, where each chromosome consists of a single chromatid. Therefore, if you observe a cell with a diploid chromosome number, it is in meiosis I; if it has a haploid number, it is in meiosis II.
The chromosome number is halved during cell division in meiosis, not mitosis.
During meiosis, the chromosome number is halved through two rounds of cell division. In the first round, called meiosis I, homologous chromosomes separate, reducing the chromosome number by half. In the second round, called meiosis II, sister chromatids separate, resulting in the final halved chromosome number.
Mitosis and Meiosis
In Anaphase I
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
There are 12 stages of meiosis. Meiosis is a type of cell that is dived, which reduces the chromosome number by half.
Meiosis is the type of cell division that results in gametes (sex cells) that possess half the chromosome number of the parent cell. In other words, meiosis reduces the chromosome number by one-half.
