Title: You are mapping three linked loci in Drosophila melanogaster (the common laborat Post by: sam01 on Mar 2, 2015 You are mapping three linked loci in Drosophila melanogaster (the common laboratory fruit fly). You cross flies that are triply mutant for apricot (pale eyes), bristle (extra bristles) and clipped (notched wings) to wild-type flies. The F1 flies are wild-type in appearance.
You then backcross the F1 females to pure-breeding (apricot, bristle, clipped) males and score the phenotypes of 1000 F2 progeny for all three loci. Here are the results: 359 wild-type 361 apricot, bristle, clipped 89 bristle, clipped 91 apricot 42 apricot, bristle 38 clipped 9 apricot, clipped 11 bristle Using these data, first determine what gametes from the F1 trihybrid produced each of the eight F2 categories. Note that apricot = aa (recessive to wild-type A); bristle = bb (recessive to wild-type B); and clipped = cc (recessive to wild-type C). Then determine if each gamete is recombinant (R) or nonrecombinant (NR) for each pair of alleles (that is, for each genetic interval).
