Meiosis involves two divisions, but the reduction in chromosome number occurs at a specific point.
During which division does the chromosome number get halved?
Correct Answer
During the first meiotic division
Explanation
The chromosome number is halved during the first meiotic division, when homologous chromosome pairs are separated into two cells. After this division, each cell has the haploid number of chromosomes (though each chromosome still consists of two chromatids). The second meiotic division then separates the sister chromatids - similar to mitosis - but does not change the chromosome number further.
