On chromosome > of the fruit fly there are three linked genes: vestigial, black, brown or bl-vg-br. The order of the genes is bl-vg-br. In my parental cross a vestigial black brown fly is mated with a wild type fly. All F1 are wild type. The F2 are the following:

1675 +++
23 bl vg br
176 bl ++
13 + vg br
57 ++ br
52 bl vg +
93 + vg +
17 bl + br

Based on this data, could construct a map of the genes? In addition, the data should fit a 3:1 ratio, based on a chi square analysis, does it?
