Meiosis outcomes: haploid but genetically diverse

Steps:

• Meiosis divides diploid cells into four haploid gametes, halving chromosome number.
• Crossing over in prophase I and independent assortment in metaphase I create genetic variation.
• Result: nuclei are haploid (n chromosomes) but not identical to each other or parent.
• Compare to mitosis, which produces identical diploid nuclei.

Why A is correct:

• Matches meiosis definition: reduces to haploid (yes) via two divisions; variation ensures non-identical nuclei (no).

Why the others are wrong:

• B: Wrong on haploid—meiosis always produces haploid nuclei for sexual reproduction.
• C: Wrong on both—meiosis creates variation (not identical) and haploid nuclei.
• D: Wrong on both—nuclei vary genetically and are haploid, not diploid/identical.

Final answer: A
