Question

what is the primary purpose of meiosis in living organisms?
○ to replicate dna for cell division
● to produce gametes (sperm and eggs) for sexual reproduction
○ to create identical daughter cells for growth and repair
○ to generate energy for cellular functions
question 2
1 pts
what are the two stages of meiosis called?
○ stage 1 and stage 2
○ mitosis i and mitosis ii
○ meiosis a and meiosis b
● meiosis i and meiosis ii

Explanation:

Question 1 (Purpose of Meiosis)

• Analyze each option:
• "To replicate DNA for cell division": DNA replication occurs before both mitosis and meiosis, not the primary purpose of meiosis.
• "To produce gametes (sperm and eggs) for sexual reproduction": Meiosis reduces chromosome number by half, forming haploid gametes essential for sexual reproduction. This matches meiosis's role.
• "To create identical daughter cells for growth and repair": This is the role of mitosis, not meiosis.
• "To generate energy for cellular functions": Energy generation is via processes like cellular respiration, not meiosis.

• Recall meiosis structure: Meiosis consists of two successive divisions, Meiosis I (separates homologous chromosomes) and Meiosis II (separates sister chromatids), similar to mitosis but with two rounds.
• Eliminate other options: "Stage 1 and Stage 2" is too vague; "Mitosis I and Mitosis II" is incorrect (meiosis, not mitosis); "Meiosis A and Meiosis B" is not the standard terminology.

Answer:

B. To produce gametes (sperm and eggs) for sexual reproduction
