Question

Quizplus · Accepted Answer

The gene for blue eyes is considered recessive because brown eyes are dominant. If both of Bob's parents carry the recessive gene for blue eyes but Bob has brown eyes, it means he inherited a dominant gene for brown eyes from one or both parents who must be carriers of the recessive blue eye gene.
