Two autosomal recessive genes, “dumpy” (dp, a reduction in wing size) and “net” (net, extra
veins in the wing), are linked on chromosome 2 of Drosophila. Homozygous wild-type females are
crossed to net, dumpy males. Among 800 F2 offspring were found: 574 wild type : 174 net, dumpy : 25
dumpy : 27 net. Estimate the map distance.
