Brown eyes is dominant to light eyes. Mr. O'Ryan has blue (light) eyes. Mrs. O'Ryan is heterozygous for brown eyes. What are the color possibilities of their son?

Brown and/or blue

Explanation:

If you cross these two eye colors, with Mrs. O'Ryan being heterozygous dominant, the produced genotype (genetic probabilty) is 50% blue eyes 50% brown eyes, so their children/child could have blue or brown eyes.
