Using the table of summarized data, look at the data that compares cleft chin versus smooth chin. What conclusions can be made about the alleles for cleft chin and smooth chin?

Using the table of your class data, compare the columns that represent the dominant and recessive alleles for each trait. Describe any trends you notice between Column A and Column B.

 Class Traits Data Table Dominant Trait A Number of students Recessive Trait B Number of students Free earlobes Attached earlobes Hair on fingers No hair on fingers Widow's peak No widow's peak Curly hair Straight hair Cleft chin Smooth chin Smile dimples No smile dimples

To find percents:

First, Column A + Column B= total number of students

Then, Divide column A by the total number of students

Last, multiply by 100.

Ex.
 Free earlobes Attached earlobes

## 12 + 5 = 17 so, free earlobes (12 / 17) * 100 = 70.59 %

We don’t need to do the math today. The website does it for us!
