Melanin synthesis (which produces pigment) in the eye is determined by 2 genes. The OCA2 gene controls melanin synthesis; MM or Mm = brown color; mm = blue color The HERC2 gene controls (“switches on”) the OCA2 gene; HH or Hh = brown color; hh = blue color. Therefore, a homozygous recessive genotype for either gene (i.e., hh or mm) results in blue eyes. Two parents, with blue eyes have the following genotypes: hhMm and Hhmm . What is the probability that they will have a brown-eyed child?  (Use the forked-line method or do a Punnet square).
