Question

why meiosis is called reductive division?
​

Answer 1

Answer:

Meiosis is sometimes called "reduction division" because it reduces the number of chromosomes to half the normal number so that, when fusion of sperm and egg occurs, baby will have the correct number.Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells. In the figures below, pink represents a genetic contribution from mom and blue represents a genetic contribution from dad. In this example, a diploid body cell contains 2n = 4 chromosomes, 2 from mom and two from dad. In humans, 2n = 46, and n = 23.
