Pedigree problems.. The family history you never knew

First, we took a short quiz to refresh our memory on codominant and sex linked traits. Then we learned about pedigree charts. These charts show how a genetic disease is passes down through a family tree. 

There are many symbols used to represent different aspects to the chart. Shaded in squares or circles means they that male or female has the genetic disease. This is useful for when considering to have a baby because it show your risks for your child to have a genetic disease. This can happen by genes on the chromosome or by sex linked traits .
