What is the ratio of the number of individuals with free earlobes to the number of attached earlobes.

Part I:

Look at the earlobes of twenty (20) unrelated individuals. Count how many of them have “free” earlobes and how many have “attached” earlobes. In the picture below, the earlobe on the right is “free” and the earlobe on the left is “attached”.

Record the number of people who can and the number of people who free and attached earlobes and answer the following questions:

What is the ratio of the number of individuals with free earlobes to the number of attached earlobes.
What can you conclude from this ratioabout the probabilities of trait of free earlobes appearing in the human population? Focus your discussion on the ratio of free to attached earlobes and what it might tell you about how the trait is inherited. (Do NOT discuss the value or effect of attached versus free earlobes).
Why is it important that the individuals in the survey were unrelated? How would a sample of related individuals affect the results?
