Some fruit flies have orange eyes and others have red eyes.
Burka [1]

Answer:

not 100% sure but

Explanation:

might be because each fruit fly has a different eye color because offspring from parents will have different eye color. or it might be from some sort of mutation that happened, that might be why they still have the gene to orange eyes. or red eyed fruit flys(or fly) migrated into a orange eyed populating and had offspring like that, that would also explain why red eyed fruit flys have the orange eyed gene.

again not 100% sure

but I hoped it helped a little
