Why is a pedigree is a useful tool to use when studying genetics? A pedigree is a useful tool to use when studying genetics because you could find the difference between your family and the sibling you have. You could also compare the things they may have in common. Like the stuff that I found out is that my family is that they go through is they have different kind of eye color for example my dad has the same color as his dad and mom and my brother and little sister Chelsea have the same eyes are my father And my mother me and my baby sister Kayla. They would want to study eye color because there are many other colored eyes that are passed down by their family and it be interesting to know why the would have the color they have know. It could also show if the generation may have eye problems and different eye color. 4). What is the dominant traits in the pedigree? Why do you think this? The dominant trait in this pedigree is light browns. I think this because that the trait is mostly run on and using a punett square, it shows that there’s a half chance that it would be light brown in the next generation. It’s a 2/4 chance so that’s how it is a dominant trait.
