Is brown eyes a dominant gene?
Understand the Problem
The question is asking whether the brown eye color trait is dominant in genetics. This touches on basic genetic principles, specifically relating to the inheritance of eye color traits.
Answer
Brown eyes are dominant over blue eyes.
The allele for brown eyes is dominant over the allele for blue eyes.
Answer for screen readers
The allele for brown eyes is dominant over the allele for blue eyes.
More Information
Genetics of eye color is more complex involving more than one gene, but in simplified Mendelian genetics, brown is dominant.
Tips
Common mistakes include thinking eye color is controlled by a single gene. Multiple genes can affect eye color, leading to variations beyond simple dominant-recessive inheritance.
