? 6. Some fruit flies have orange eyes and others have red eyes.
If two orange-eyed fruit flies are crossed, their offspring always have orange eyes.
If two red-eyed fruit flies are crossed, their offspring sometimes include both orange-eyed and
red-eyed flies.
What can be concluded from these observations?

A Crossing an orange-eyed fly with a red-eyed fly will produce a 1:1 ratio in the offspring.
B. The allele lor orange eyes is dominant.
C. The allele for red eyes is dominant.

D
We could determine which allele is dominant only by doing a cross that produces a 3:1 ratio.
