1. 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. B. 46, 23, 23 Correct. The chromosome number is reduced to one half during the first meiotic division. Recall that the number of chromosomes is determined by the number of centromeres, and not the number of chromatids. 2. The process of meiosis produces four cells with nonidentical chromosomes. This diversification occurs during: B. prophase 1 Correct. Prophase I includes recombination of genetic material and the random arrangement of the homologous pairs, producing diversification of the resulting haploid cells. 3. Which of the following is unique to mitosis and not a part of meiosis? D. homologous chromosomes behave independently Correct. Pairing of homologous chromosomes allowing independent segregation and crossing over is unique to meiosis. In mitosis, homologous chromosomes behave independently.
