In zebrafish, three genes have been mapped on the third chromosome, in the order fiz---6 m. u.---myob14 m. u.sufi The wild-type allele of each gene is dominant. A strain that is fiz myob sufi / + + + is testcrossed, and there are 1000 offspring fish.

(1) How many wild-type offspring would you expect to see in these 1000 offspring?
(2) How many fiz + + offspring would you expect to see in these 1000 offspring?

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.

other information encoded in your genes might distinguish you from the others in the group
