Hypercholesterolemia is a genetic disorder that causes blood cholesterol levels to be 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 heterozygous for hypercholesterolemia. what is the probability that their first child will have normal levels of blood cholesterol?

1 (100%)

Explanation:

H allele is incompletely dominant to the h allele =Hh ( normal levels of blood cholesterol)

hh homozygotes having extremely high levels of blood cholesterol =hh

If Hh × hh

The F1 generation = Hh, Hh, hh, hh

The probability that their first child will have normal levels of blood cholesterol;

= 1/1

= 1 (100%)

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
