In a typical diploid organism, what is the outcome of meiosis?
A
Two genetically identical diploid daughter cells
B
One diploid cell with duplicated chromosomes (sister chromatids still joined)
C
Four genetically identical haploid cells
D
Four genetically diverse haploid cells with half the original chromosome number
Verified step by step guidance1
Recall that meiosis is a type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid parent cell.
Understand that meiosis consists of two successive divisions: meiosis I and meiosis II, each with distinct roles in chromosome separation.
In meiosis I, homologous chromosomes (each consisting of two sister chromatids) are separated into two cells, reducing the chromosome number from diploid to haploid.
In meiosis II, the sister chromatids of each chromosome are separated, resulting in four haploid cells.
Because of crossing over during prophase I and the random assortment of homologous chromosomes, the four haploid cells are genetically diverse, not identical.
