Eye Color Genetics
As the saying goes, “the eyes are the windows to the soul”. Our eyes are also a window into our genes. Like many of our physical features, eye color is determined by genetics.
Although there are only a few eye colors, there are many gene combinations. Examining eye color genetics can be a great way to understand genetics as a whole. In this experiment we will study eye color genetics by predicting eye color inheritance among family members.
Problem:
How do we inherit our eye color?
Materials:
- Families
-
- Biological Mother
- Biological Father
- Offspring
Procedure:
For this experiment you can also use your own family.
- Observe eye color for each family member. If possible, find out the grandparents’ eye colors as well. You can define the color using the Martin-Schultz scale.
- Determine the genotypes of the parents.
- Using a Punnett square, determine the color possibilities for the children.
- Compare the theoretical probability and actual eye color of the children.
