The correct answer is B. Brown eyes are dominant. Each parent has a brown gene and a blue gene. Their child got the blue gene from each parent and has two blue genes which is the only way recessive genes are phenotypically expressed.
Monogenetic disorders are caused by a mutation in a single gene. The mutation may be present on one or both chromosomes (one chromosome inherited from each parent). Examples of monogenic disorders are: sickle cell disease, cystic fibrosis, polycystic kidney disease, and Tay-Sachs disease.
