If meiosis did not occur in sexually reproducing organisms, ____.

Question

Quizplus · Accepted Answer

Meiosis is necessary in sexually reproducing organisms to maintain the chromosome number in each generation. Without meiosis, the chromosome number would double in each generation, leading to an unstable and unviable genome. Mitosis alone cannot maintain the correct chromosome number because it results in the formation of identical daughter cells with the same chromosome number as the parent cell. Therefore, D is the correct answer.

If Meiosis Did Not Occur in Sexually Reproducing Organisms, ____
