Analysis: 1. What Characteristic is shown in the pedigree? The characteristic in the pedigree are eyes! 2. How many family members are shown in the pedigree? 10 including me 3. Why is a pedigree a useful tool to use when studying genetics? You can use the steps to see if the offspring is dominant or recessive. You can see the history of your family and see who was the unique one. 4. What is the Dominant trait in the pedigree? Why do you think this? Brown eyes... I think this because I looked at the chart and saw the dominant train was brown eyes! Sometimes you may think... one color shows up more often, well that doesnt mean that trait is dominat. To find out the dominant trait, you have to go through a process. What helped me was Johnathen gave us a chart and the one we landed on what was dominant and if you get unknown, you went to the wrong path!
