In eukaryotic cells, how many rounds of cell division occur during mitosis versus meiosis?
A
Mitosis: 1 division; Meiosis: 1 division
B
Mitosis: 2 divisions; Meiosis: 2 divisions
C
Mitosis: 2 divisions; Meiosis: 1 division
D
Mitosis: 1 division; Meiosis: 2 divisions
Verified step by step guidance1
Understand the basic definitions: Mitosis is a process of cell division that results in two genetically identical daughter cells, while meiosis is a specialized form of cell division that reduces the chromosome number by half, producing four genetically diverse gametes.
Recall that mitosis involves a single round of division, where one parent cell divides once to produce two daughter cells, maintaining the original chromosome number.
Recognize that meiosis consists of two consecutive rounds of cell division, called meiosis I and meiosis II, which together reduce the chromosome number from diploid to haploid.
Note that meiosis I separates homologous chromosomes, and meiosis II separates sister chromatids, resulting in four haploid cells from one diploid cell.
Conclude that the correct comparison is: mitosis involves 1 division, and meiosis involves 2 divisions.
