72.

Lisa learned that blue eye color is a recessive trait and brown eye color is a dominant trait. She became puzzled because she and her sister, Sara, both have blue eyes. Her parents, Joan and Greg, both have brown eyes. Lisa wants to know how she and her sister could both have blue eyes. As shown above, Lisa drew her family tree (pedigree) beginning with both set of grandparents. Why does Lisa have blue eyes?

a)

Eye color is not a hereditary trait, so Lisa and her sister did not inherit their eye color from their parents.

b)

Their parents both have an allele for blue eyes, but it is not expressed.

c)

Blue eye color is a trait that is expressed every other generation.

d)

The grandparents' genes for eye color are not influencing Lisa and her sister's genes for eye color.
