Question

part b
which pieces of evidence best support the answer to part a?
select two correct answers.

a. mutations occurred in the group not exposed to x - rays.

b. the pink eyes and ebony bodies are mutated versions of the genes.

c. flies that were exposed to x - rays had offspring with lethal mutations and nonlethal mutations.

d. all the alleles for eye color and body color were present in the parent flies but in different combinations.

e. the eye color and body color combinations seen in the offspring flies were not seen in the parent flies.

Explanation:

To support the answer (assuming Part A's answer relates to genetic recombination/mutation), we analyze:

• Option D: Parent flies had all alleles but in different combos, so offspring can have new combos via recombination (supports non - mutation - driven new traits).
• Option E: Offspring have new color combos not in parents, showing new trait combinations (from recombination, not new mutations).

Options A, B, C relate to mutations, which don't support if the answer is about non - mutation - based trait appearance.

Answer:

D. All the alleles for eye color and body color were present in the parent flies but in different combinations.
E. The eye color and body color combinations seen in the offspring flies were not seen in the parent flies.
