fruit fly lab- think it is impossible

Submitted by Anonymous (guest) on Mon, 01/14/2008 - 2:45am.

i need help with this lab, i don't think it is possible for the results.

the p1 sepia is female and the p1 male is wild.
the cross is sepia(brown) x wild (red). i have in the f1 3 red male, 3 red females, 1 brown male , and 0 brown female. in the f2 i have 52 red males with wings and 3 red males without wings. The female red with wings are 47and without wings it is 7. The male brown is 24 with wings and 3 without wings. The female brown is 26 with wings and 2 without wings.

how could the traits be inherited and what could be the type of inheritance. what kind of explanation can you give of the statistics. what would the punnett square look like because i cannot justify any of the data.
is it autosomal, dominant, recessive or sex linked?
thank you very much.
