Select the statement(s) that accurately compares mitosis and meiosis.
Mitosis consists of one cell division, whereas meiosis consists of two cell divisions.
In mitosis, two genetically identical daughter cells are created. In meiosis, four genetically unique daughter cells are created.
Mitosis results in the formation of haploid cells. Meiosis results in the formation of diploid cells.
Crossing over and independent assortment during mitosis increases genetic diversity.
Mitosis is associated with asexual reproduction. Meiosis is associated with sexual reproduction.
The accurate statements comparing mitosis and meiosis are:
1. Mitosis consists of one cell division, whereas meiosis consists of two cell divisions.
2. In mitosis, two genetically identical daughter cells are created. In meiosis, four genetically unique daughter cells are created.
3. Mitosis is associated with asexual reproduction. Meiosis is associated with sexual reproduction.
Explanation:
– Mitosis involves one division, leading to two identical cells, while meiosis has two divisions that produce four unique cells.
– Mitosis is often seen in asexual reproduction (e.g., in growth and repair), while meiosis is crucial for producing gametes in sexual reproduction.
– The statement regarding haploid and diploid cells is incorrect; mitosis produces diploid cells (if starting from diploid), and meiosis produces haploid cells.
– Additionally, crossing over and independent assortment occur during meiosis, not mitosis, which contributes to genetic diversity.
