Multiple Choice
In a typical diploid organism, one full cycle of meiosis starting from a single diploid germ cell produces which of the following outcomes?
A
Two haploid cells that are genetically identical to each other
B
Four diploid cells that are genetically distinct from one another
C
Four haploid cells that are genetically distinct from one another
D
Two diploid daughter cells that are genetically identical to the parent cell
Verified step by step guidance1
Recall that meiosis is a specialized 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 consecutive divisions: meiosis I and meiosis II, which together result in four daughter cells.
Recognize that during meiosis I, homologous chromosomes separate, which reduces the chromosome number from diploid (2n) to haploid (n), and crossing over occurs, creating genetic variation.
During meiosis II, the sister chromatids separate, similar to mitosis, resulting in four haploid cells that are genetically distinct due to recombination and independent assortment.
Conclude that the outcome of one full cycle of meiosis starting from a single diploid germ cell is four haploid cells that are genetically distinct from one another.
