Lots of money is spent on special diets and surgery every year. Finally, when they face the reality that things are not working out as dreamed, they too turn to their parents, teachers, and doctors for some answers. There is a growing concern among the students as to why their physiological make-up is what it is. The answer to many of their questions lies in the genes, dominant and recessive traits.

Human beings are what they are because of the genes that they inherited from their parents.
The basic heredity principal discovered by Mendel, applies to humans as well as to plants. This unit will be used in a seventh-grade Life Science class and can be used in grades six through eight. Genetics has to do primarily with the passing of traits from generation to generation. This is done through the passing of genes which are located on the chromosomes. Each individual inherits 23 pairs of chromosomes from each parent.
