If a blue-eyed man marries a brown-eyed lady whose mom had blue eyes, we'd count on 0.50 or 50% of the kids in this family to have blue eyes. let's examine how that is decided.
Someone with brown eyes may be wearing one blue allele and one brown allele, so a brown-eyed mother and a blue-eyed father ought to give birth to a blue-eyed infant.
Remember that exclusive versions of genes can be dominant or recessive. What this means is that when you have one copy of every model of a gene, one will win out over the other. So a person with a brown OCA2 (B) and a blue OCA2 (b) could have brown eyes. due to the fact that brown (B) is dominant over blue (b).
