Meiosis starts with a single diploid cell and produces which of the following?

• A. Four haploid cells
• B. Two diploid cells
• C. Two haploid cells
• D. Four diploid cells

Answer: (A)

Verified step by step guidance

1. Understand the concept of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of haploid cells from a diploid parent cell. This process is essential for sexual reproduction.
2. Recall the stages of meiosis: Meiosis consists of two consecutive divisions, Meiosis I and Meiosis II. Meiosis I separates homologous chromosomes, while Meiosis II separates sister chromatids.
3. Analyze the outcome of Meiosis I: After Meiosis I, the diploid cell divides into two haploid cells, each containing half the original chromosome number.
4. Analyze the outcome of Meiosis II: Each of the two haploid cells from Meiosis I undergoes a second division, resulting in four haploid cells. These cells are genetically distinct due to crossing over and independent assortment during Meiosis I.
5. Match the correct answer: Based on the process described, meiosis produces four haploid cells. This matches the first option provided in the question.
