Ok I don't even know where to begin with this problem A hairy-winged (h) Drosophila female is mated with a yellow bodied (y), white-eyed (w) male. The F1 flies are normal. The F1 progeny is then inter-bred. The F2 generation has the following phenotypic ratios- give the genotypes of its parents and the F1 (for each sex). List linkage relationship and calculate map distances. Can someone lead me through this?
