Question

which statement is false regarding incomplete dominance?
heterozygotes for the condition experience a mild form of the disease.
heterozygotes for the disease experience haploinsufficiency.
an example is when a curly - haired parent and a straight - haired parent have a wavy - haired child.
it occurs when one allele does not completely mask the presence of the other allele.
phenylketonuria (pku) is an example.

Explanation:

• Incomplete dominance involves a blended phenotype in heterozygotes (e.g., wavy hair from curly/straight parents) where neither allele fully masks the other; heterozygotes may show mild traits. Haploinsufficiency is a separate genetic mechanism (one functional allele is insufficient), not incomplete dominance. PKU is a recessive disorder, not an example of incomplete dominance. Thus, B and E are false.

Answer:

B. Heterozygotes for the disease experience haploinsufficiency, E. Phenylketonuria (PKU) is an example.
