Are brown eyes a dominant trait?
Understand the Problem
The question is asking whether brown eyes are considered a dominant genetic trait. This relates to the principles of genetics and inheritance.
Answer
The allele for brown eyes is dominant.
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
Eye color inheritance is complex and can involve multiple genes. Brown is generally dominant over both blue and green eyes. However, variations can occur due to the involvement of multiple genes affecting melanin concentration in the iris.
Tips
Students often mistakenly believe that eye color is determined by a single gene. It is actually influenced by multiple genes, making the inheritance patterns more complex.
