The brown allele is always dominant over the green and blue alleles, the green allele is always dominant over the blue allele, and the blue allele is always recessive. Because of this, it is possible for two brown-eyed parents to have a child with a different eye color than theirs.For two brown-eyed parents to have a blue-eyed child, for example, the mother and father would need to pass on a pair of blue alleles each to their offspring.he brown allele is always dominant over the green and blue alleles, the green allele is always dominant over the blue allele, and the blue allele is always recessive. Because of this, it is possible for two brown-eyed parents to have a child with a different eye color than theirs.
