Color Blindness Problem Set

Problem 8: Grandparents

We don't know if any of Audrei's grandparents were red-green color blind, but we can make some educated guesses. Is it possible that all of Audrei's grandparents have normal vision?

A. Yes
If both grandmothers were heterozygous carriers, each could have passed down the source of the color perception allele to their respective children.
B. No
