4) 24 and 12
One of the two cell divisions is meiosis. From a single parent cell, it generates four daughter cells. Each cell has half of the parent cell's chromosomes. Meiosis I and Meiosis II are the two primary mechanisms that cause meiosis. Four subdivisions make up each meiosis. In meiosis I, anaphase I takes place, and in meiosis II, anaphase II. The homologous chromosomes are pulled apart and moved to the opposite ends of the cell during anaphase I, whereas during anaphase II, the sister chromatids of each chromosome are separated and moved towards the poles. Additionally, anaphase I happens when a cell is in the diploid condition, but anaphase II happens when a cell is in haploid condition.
The cell has 12 chromosomes, after anaphase I stage each chromatid is considered a separate chromosome structure, hence there will be 24 chromosomes. After meiosis I is complete the number of chromosomes again become 12 because of the division of the nucleus.
At anaphase II, the sister chromatids are separated hence, the number of chromosomes remain 12.
