Chapter 2, Problem 1MC
Summary Introduction
Introduction:
The cell divides by two method meiosis and mitosis. Meiosis is called as reductional division because the daughter cells get half the number of chromosomes that were present in the parent cell and mitosis is called non-reductional cell division as the parent cells, and the daughter cell possess equal number chromosomes.
