What process produces four genetically diverse haploid gamete cells from a single diploid germ cell?
Answer and explanation
Correct answer: B. Meiosis
- Step 1: Gamete formation requires reducing chromosomal ploidy from diploid () to haploid ().
- Step 2: Meiosis involves two sequential nuclear divisions (Meiosis I and II) with crossing over in Prophase I, producing four genetically distinct haploid gametes.
Answer
Meiosis.
Why not the others: 'Mitosis' produces two genetically identical diploid somatic cells; 'Binary fission' is asexual reproduction in prokaryotes; 'Budding' is asexual reproduction in yeast and hydra.
