Question
Meiosis is characterized by
Reduction division
Equal division
Both reduction and equal division
Paining of non-homologous chromosomes
Reduction division
Equal division
Both reduction and equal division
Paining of non-homologous chromosomes
Hint:
If there are 24 chromosomes in the parent cell the daughter cells will have 12 chromosomes.
The correct answer is: Reduction division
- Meiosis is sometimes called "because it reduces the number of chromosomes to half the normal number. So when the sperm and egg fuse, the baby will have the correct number.
- Therefore, the purpose of meiosis is to produce gametes, sperm, and eggs with half the genetic complement of the parent cell. For example, a diploid somatic cell contains 2n = 4 chromosomes, 2 from the mother and 2 from the father. In humans, 2n = 46 and n = 23.
