Discussion:
Brown and blue eyes genotypes
Genetically speaking, brown eyes (B-) are dominant to blue eyes (bb). However, an individual can wear colored contacts in order to change his or her eye phenotype. Suppose a man with blue eyes (bb) marries a woman who appears to have blue eyes and together they have five children. Listed below are three possible outcomes.
Given the outcomes below, what is the most likely genotype for the woman.
(a) Outcome 1: All five children have blue eyes.
(b) Outcome 2: Three children have blue eyes and two have brown eyes.
(c) Outcome 3: All five children have brown eyes.
