Hypercholesterolemia is a disorder in which blood cholesterol levels are elevated. the h allele is incompletely dominant to the h allele, with hh homozygotes having extremely high levels of blood cholesterol. a husband and wife are both hh heterozygotes. what is the chance that their first child will have normal levels of blood cholesterol?

25 %

Explanation:

Given -

H allele is incompletely dominant to the h allele

Thus,

HH represents normal level of  blood cholesterol levels

Hh represents intermediate level of blood cholesterol levels

hh represents high level of blood cholesterol levels

Parents genotype  - Hh (heterozygous)

Thus F1 generation cross would be between Hh and Hh

Hh * Hh

HH, Hh, Hh, hh

Out of four only one (HH offspring) has normal levels of blood cholesterol

Thus the percentage is
