What is the expected genotypes and phenotypes of F1 flies in the cross between virgin brown eyed female with scarlet males (genes for brown and scarlet eyes are on different autosomes)?

I know that brown eyes and scarlet eyes are both recessive but I'm not sure what he genotype of the parents would be

brown eyes = bw
scarlet eyes = st

What does it mean when the genes are on different autosomes?
Answered by PsyDAG
An autosome is a chromosome that is not an allosome (i.e., not a sex chromosome). Autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell, whereas members of an allosome pair (XX, XY) may differ from one another and thereby determine sex.

Would the parent female genotype be... bw/bw,st+/st+ ? and the male genotype be... bw+/bw+,st/st ?
