Question

In both mitosis and meiosis, sister chromatids separate during anaphase. But the number of haploid and diploid cells produced by meiosis and mitosis are

• A. 6 and 3
• B. and 2
• C. 2 and 4
• D. 3 and 6

Hint:

Remember: Mitosis = 1 division \(\rightarrow\) 2 diploid cells; Meiosis = 2 divisions \(\rightarrow\) 4 haploid cells.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Mitosis and meiosis are the two main types of nuclear division in eukaryotic cells, differing in their biological roles and the number and ploidy of their resulting daughter cells.

Step 2: Detailed Explanation:
- Mitosis is a single equational division that preserves ploidy.
The cell replicates its DNA once and divides once, distributing identical sister chromatids into two daughter cells.
This process maintains the parental chromosome number, producing 2 diploid (\(2n\)) somatic cells.
- Meiosis is a reductional division process involved in sexual reproduction.
A diploid cell replicates its DNA once, which is followed by two successive rounds of division (Meiosis I and Meiosis II).
This process separates homologous chromosome pairs first, and then sister chromatids, producing 4 haploid (\(n\)) gametes.

Step 3: Final Answer:
Meiosis produces 4 haploid cells, while mitosis produces 2 diploid cells.
