Question

Mitosis and meiosis result in the following chromosome complements, respectively:

A n, 2n
B 2n, n
C Haploid, diploid
D 2n, 2n
E n, n

Answer 1

Mitosis results in diploid daughter cells (2n), while meiosis results in haploid daughter cells (n), making the correct answer '2n, n'.

Step-by-step explanation:

Mitosis and meiosis result in different chromosome complements. Mitosis results in daughter cells that have the same number of chromosomes as the parent cell. If the parent cell is diploid (2n), the daughter cells will also be diploid. On the other hand, meiosis results in daughter cells that have half the number of chromosomes as the parent cell, making them haploid (n). This is because meiosis includes one round of chromosome duplication but two rounds of nuclear division, ultimately resulting in four haploid daughter cells from a single diploid parent cell.

Therefore, the correct answer to the question is option 'B', which is 2n, n. In mitosis, a diploid cell divides to produce two diploid cells (2n, 2n), whereas in meiosis, a diploid cell divides to produce four haploid cells (2n, n).
