If she receives a dominant allele from one parent and a recessive gene from the other (Bb) she will also have brown eyes. But if she receives recessive alleles from both parents (bb), she will have blue eyes. Thus, in the case of Bb (dominant and recessive), brown (B) dominates and determines the eye color.
