Problem 1: Number of chromosomes

A human cell has 46 total or 23 pairs of chromosomes. Following mitosis, the daughter cells would each have a total of ______ chromosomes. After meiosis I, the two daughter cells would have _____chromosomes, and after meiosis II ______ chromosomes.

C. 23, 23, 23
Incorrect.
Mitosis exactly duplicates the genetic material giving 46 chromosomes to each daughter cell. Meiosis reduces the number of chromosomes to a haploid number (23).
