Key Words
- DNA
- gene
- chromosome
Steps
Review the background information on Cells before starting.
Survey your class for a genetic trait (attached vs. free earlobes, tongue rolling, hitchhiker's thumb). Create a bar graph of the results.
Look for patterns in your observations.
Make a graph or chart showing your results.
