Color Blindness Problem Set


Problem 6: Pedigree representation for Paul

Paul, like Liz, is color blind. How will he be represented in the family pedigree?


To be color blind, Paul had to have inherited an X-chromosome with the red-green color blind allele from his mother and a Y chromosome from his father. Therefore, he is represented by the symbol of the males affected with the color blindness.
