This web-based practice provides students with an interactive experience during a genetics unit. Through this hands-on manipulative, students explore how eye color is determined. This site also has the Hardy-Weinberg calculations, which can be used as reinforcement for students.

What Color Eyes Would Your Children Have?

20 minutes

1. Working either alone or in pairs, group the students according to your learning environment and the number of computers accessible.
2. Students will navigate to the interactive at http://museum.thetech.org/ugenetics/eyeCalc/eyecalculator.html
3. Using the interactive, students can explore various scenarios regarding the relationship of eye color between parents and children.
4. Extension: Students draw the flow charts from one of their scenarios and then determine which genes are recessive and which are dominant.
