Question

1. cells produced by meiosis are haploid (___ chromosomes) and those produced by mitosis are diploid (___ chromosomes).

a. 10,20
b. 23,46
c. 25,50
d. 52,104

Explanation:

In human cells, meiosis produces haploid cells (gametes) with 23 chromosomes (half the diploid number). Mitosis produces diploid cells (somatic cells) with 46 chromosomes (the full set). Option b has 23 (haploid from meiosis) and 46 (diploid from mitosis), matching this. Other options don't correspond to human chromosome counts.

Answer:

b. 23, 46
