What is the mode of inheritance of this trait? b. what is the penetrance of this trait [that is, the ratio between the number of individuals in the pedigree who display the trait (numerator), and the number of individuals you know from the pedigree must have the trait-determining genotype regardless of whether they have the trait or not (denominator)]? c. using your answer to part (b) above, what would you tell the parents about the numerical likelihood their expected child will have split-hand deformity?

sorry, but you do not have posted the diagram.

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.

wha is what i will use to get my free points
