CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False Mitosis does not usually produce variation between offspring but meiosis does
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Mitosis builds a person with an identical set of chromosomes in every cell. And meiosis generates reproductive cells with new combinations of gene variations.

Detailed explanation-2: -Mitosis. Asexual reproduction uses the process of mitosis to create the identical copies (clones) of the parent cell. It therefore leads to offspring that show no genetic variation.

Detailed explanation-3: -The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

Detailed explanation-4: -5. Assess how meiosis contributes to genetic variation, while mitosis does not. During meiosis, the independent assortment of the pairs of chromosomes and crossing over provide a large amount of genetic variation. Mitosis produces identical cells.
