In the fruit fly,sepia eye is recessive to red eye and curved wing is recessive to straight wing. If a pure-breeding red-eyed curved-winged fly, what phenotypes will appear in the F, generation? If two F, flies are allowed to mate what phenotypes will appear in the F, generation and in what ratio? Can some one pleas answer and EXPLAIN this question to and like how you got the answer for it because I am so lost

I didnt get your 'pure-breeding' thing... If its lyk what i thought then it should b lyk this...
Let,
RR=Red Eye (dom)
rr=sepia eye (res)
SS=Straight wing (dom)
ss=curvd wing (res)
what i considered your pure breed red eye curvd wing as (RRss). Which gives gametes as (Rs). On fusing wit gamete of another red eye curved wing it forms (RRss), which is a red eye curvd wing again, in the F, generation!
This (RRss) of F, generations had 'fun' :) in d same way to produce more (RRss) offsprings.

That depends, is the red eyed fly heterozygous red eyed or homozygous red eyed? Also, you wrote "If a pure breeding red eyed curved winged fly, what phenotypes will appear in the F generation?" What do you mean by that? If it mates with another fly? That sentence isn't complete, try writing out the question exactly as it appears from your hw.
