Question

ds. this happens because
have no eyes because they
learned about these
ext an entire organ.
mlar dna code as the ey gene
se has an eye, and it does not
e eye gene of mice into the
which question will best help the scientist evaluate the
claim?
a. will the fruit fly express any other mouse traits?
b. will the fruit fly have better eyesight than other
fruit flies?
c. will the mouse’s dna cause a mutation in the fruit
fly’s eye genes?
d. will the mouse’s dna cause the fruit fly to
produce a fruit fly eye or a mouse eye?

Explanation:

The claim likely relates to gene function (mouse eye gene in fruit fly). Option D directly addresses the outcome of the mouse DNA on the type of eye the fruit fly produces, which is key to evaluating the claim about gene expression. Other options focus on unrelated traits (A), eyesight (B), or mutations (C) instead of the core gene - to - organ outcome.

Answer:

D. Will the mouse’s DNA cause the fruit fly to produce a fruit fly eye or a mouse eye?
