Color Blindness Problem Set

Problem 5: Pedigree representation for Liz

Correct!

In her message, Audrei also tells us that her sister Liz and brother Paul are also color blind, but that her brother David has normal vision. How will Liz be represented on the family pedigree?

Liz inherited one X-chromosome from each of her parents. She received an X-chromosome with the red-green color blind allele from her father and one from her mother.
