Question
In a series of two-point mapping crosses involving five genes
located on chromosome II in Drosophila, the following recombinant
(single-crossover) frequencies were observed:
pr–adp 29%
pr–vg 13
pr–c 21
pr–b 6
adp–b 35
adp–c 8
adp–vg 16
vg–b 19
vg–c 8
c–b 27
(a) Given that the adp gene is near the end of chromosome II
(locus 83), construct a map of these genes.
(b) In another set of experiments, a sixth gene, d, was tested
against b and pr:
d–b 17%
d–pr 23%
Predict the results of two-point mapping between d and c, d and
vg, and d and adp.
