1 Answer

  • Answer:

    Brown eyes are a dominant trait.

    Explanation:

    Brown eyes are a dominant trait, and blue eyes are a recessive trait. If the father has brown eyes, they can have either a BB or Bb genotype; the mother must have a bb genotype in order for her eyes to be blue.

    Refer to the Punnett Square below to see how it's possible for this mother and father to produce children with both colored eyes.
