Question 10 Listen A particular gene affects eye size in fruit flies. For one dominant allele, 99% of the flies carrying this allele have smaller eyes, but most are only about 10% smaller than flies that are homozygous for the recessive allele. This is in contrast to a different dominant allele in which the eyes are only 30% of the size of the flies that are homozygous recessive. True or False: This allele is highly penetrant but shows low expressivity a) True b) False

A particular gene affects eye size in fruit flies. For one dominant allele, 99% of the
flies carrying this allele have smaller eyes, but most are only about 10% smaller than
flies that are homozygous for the recessive allele. This is in contrast to a different
dominant allele in which the eyes are only 30% of the size of the flies that are
homozygous recessive. True or False: This allele is highly penetrant but shows low
expressivity
a) True
b) False
