Explain why meiosis i is a reductive division
WebMeiosis is called reduction division because the number of chromosomes in the daughter cells are half that of the parent cell. Significance of Meiosis: 1. Meiosis reduces the chromosome number to half in the daughter cells … WebExplain why meiosis I is a reduction division but meiosis II is not. Meiosis I is a reduction division because homologs separate---daughter cells have just one of each type of chromosome instead of two.
