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? select all statements that are true.

1) progeny with eye pigment have a p {miniwhite +} insertion they inherited from their father.
2) progeny with notched wings inherited the non-deleted chromosome 3 from their mother.
3) progeny with normal wings inherited the chromosome 3 with the deletion from their mother.
4) progeny with notched wings and eye pigment have both a p {miniwhite +} insertion and the chromosome 3 with the deletion.
5) progeny with normal wings and eye pigment have both a p {miniwhite +} insertion and the chromosome 3 with the deletion.
6) a cross that produces progeny with normal wings and eye pigment indicates that the p-element insertion has disrupted an essential gene in the region spanned by the deletion.
7) a cross that does not produce progeny with normal wings and eye pigment indicates that the p-element insertion has disrupted an essential gene in the region spanned by the deletion.
