Detailed explanation-1: -Overall, meiosis results in the formation of four haploid cells from a diploid parent cell. So if a cell has 12 chromosomes at the end of meiosis I which is reduction division, it means that the parent cell would have had 24 chromosomes in prophase I.
Detailed explanation-2: -24. After mitosis, two identical cells are produced with the same original number of chromosomes of the parent’s cell. In this case, if a cell has 12 chromosomes, each daughter cell will have 12 chromosomes after mitosis.
Detailed explanation-3: -1) The diploid cell has 6 chromosomes. 2) During Meiosis, the two sets of chromosomes line up on the Metaphase I plate and exchange genetic material. 3) This process results in 24 new chromosomes.
Detailed explanation-4: -In plant-A, 2n= 12, n= gametic chromosome number. This means the number of chromosomes in a gamete of plant A is 6 and gametes will fuse to form a diploid organism having 12 chromosomes in each cell.
Detailed explanation-5: -A diploid cell with 12 chromosomes (6 homologous chromosome pairs) goes through meiosis.
