A. The number of chromosomes is reduced by half.
The correct answer is A. The number of chromosomes is reduced by half.
During meiosis, which is a type of cell division specific to reproductive cells (gametes), the original cell with a diploid number of chromosomes (two sets of chromosomes) goes through two rounds of division. This results in four daughter cells, each with a haploid number of chromosomes (half the original number of chromosomes).
The reduction in the number of chromosomes is achieved through two divisions called meiosis I and meiosis II. During meiosis I, homologous pairs of chromosomes separate, resulting in two daughter cells, each with a haploid set of chromosomes. These daughter cells then undergo meiosis II, where the sister chromatids of each chromosome separate, creating four haploid daughter cells. Therefore, the number of chromosomes is halved in each of the resulting cells compared to the original parent cell.
