A heterozygous brown-eyed (B) woman marries a blue-eyed (b) man. The
woman has extreme nearsightedness, a condition that required her to wear
glasses at a very young age. Near-sightedness is recessive. The man has
normal vision, but his mother had extreme near-sightedness. Determine the
parents’ genotypes. Then, show the Punnett square and phenotypic ratio.
Lastly, what is the probability that they will have a child that is nearsighted and
brown-eyed?
