Question

How is mitosis different from meiosis? a. mitosis occurs only in single-celled organisms, while meiosis occurs in single-celled and multicellular organisms. b. mitosis occurs less often in a multicellular organism than meiosis. c. mitosis creates two daughter cells, and meiosis creates four daughter cells. d. mitosis does not pass genetic information to daughter cells, while meiosis does pass genetic information to daughter cells.

Answer 1

Mitosis results in genetically identical cells, while meiosis produces genetically distinct cells with half the number of chromosomes.

Step-by-step explanation:

Meiosis and mitosis are both forms of division of the nucleus in eukaryotic cells. They share some similarities, but also exhibit distinct differences that lead to their very different outcomes. Mitosis is a single nuclear division that results in two nuclei, usually partitioned into two new cells. The nuclei resulting from a mitotic division are genetically identical to the original. They have the same number of sets of chromosomes: one in the case of haploid cells, and two in the case of diploid cells.

On the other hand, meiosis is two nuclear divisions that result in four nuclei, usually partitioned into four new cells. The nuclei resulting from meiosis are never genetically identical, and they contain one chromosome set only—this is half the number of the original cell, which was diploid.
