Genetics and Heredity Preview Organisms are not like billiard balls, moved by simple  external forces to predictable positions on life’s table.  Environmental experiences and biological foundations  work  together  to make us who we are.  Today’s topic focuses on genetic foundations and the  interaction of heredity and environment.

Genes and Chromosomes Get passed from generation to generation and end up in  all of the trillion cells in the body. Mitosis, Meiosis, and Fertilization. All cells in the human body, except the sperm and egg,  have 46 chromosomes arranged in 23 pairs. These cells reproduce by a process called mitosis . Reproductive cells reproduce by a process called meiosis . Fertilization is the process in which an egg and a sperm  fuse to create a single cell called the  zygote .
