Three loci are found to be located (linked) on chromosome 2 in fruit flies. At locus 1, wild is dominant over tall (a). For locus 2, wild is dominant over red (b) and for locus 3, wild is dominant over bent (c). Assume that a standard trihybrid backcross is made and the following progeny are produced:
tall red bent 300
wild 280
red bent 11
tall 12
tall bent 41
tall red 160
red 39
bent 162
**What is the distance between the locus for tall (a) and the locus for red (b)?
**What is the distance between (a) and (c)?
