Chapter 14, Problem 1SYK
Summary Introduction
To relate:
Introduction: Gregor Johann Mendel, who is known as the ‘Father of modern genetics’, conducted experiments with seven characteristics of pea plant and proposed the laws of inheritance. Meiosis is the reduction division, which occurs in diploid cells and reduces them to haploid cells. It plays an important role in the formation of gametes from germ cells.
