Once meiosis is complete in a diploid organism, what is the end result?
A
Four genetically distinct haploid daughter cells (gametes), each with half the original chromosome number
B
Four genetically identical diploid daughter cells, each with the same chromosome number as the original cell
C
Two genetically distinct haploid daughter cells, each with half the original chromosome number
D
Two genetically identical diploid daughter cells, each with the same chromosome number as the original cell
검증된 단계별 안내1
Recall that meiosis is a type of cell division that reduces the chromosome number by half, producing cells that are haploid (n) from an original diploid (2n) cell.
Understand that meiosis consists of two successive divisions: meiosis I and meiosis II, which together result in four daughter cells.
Recognize that during meiosis I, homologous chromosomes separate, reducing the chromosome number from diploid (2n) to haploid (n), but each chromosome still consists of two sister chromatids.
During meiosis II, the sister chromatids separate, resulting in four haploid cells that are genetically distinct due to crossing over and independent assortment.
Conclude that the end result of meiosis is four genetically distinct haploid daughter cells (gametes), each containing half the chromosome number of the original diploid cell.
