When the researcher examines the progeny with eye pigment that result from these crosses, she finds two different categories of flies. Some crosses produce flies with eye pigment and notched wings, as well as flies with eye pigment and normal wings. Other crosses produce flies with eye pigment and notched wings, but no flies with eye pigment and normal wings. What might explain these results

The explanation of the question is given below.

Explanation:

Progeny through eyes pigment P injection transmitted through their parent.  Progeny including slotted wings transmitted the non-suppressed chromosome three from ones parents.  Progeny with average wings acquired chromosome three from their parents.Progeny of natural wings including pigment of the eye has both P addition and chromosome 3 removal.  A crossing that doesn't even yield offspring with regular wings as well as eye pigments suggests that perhaps the addition of the P component has damaged the critical gene throughout the removal area.

Nimbostratus is the correct answer.
explanation: nimbostratus clouds are the type of clouds that are mostly likely present on gray, rainy day. these clouds produce continuous rain, snow and there is no thundering or lightening either.
