Questions

In cоrn, the genes Pl fоr purple leаves (dоminаnt over pl for green leаves), sm for salmon silk (recessive to Sm for yellow silk) and py for pigmy plant (recessive to Py for normal size plant) are all on chromosome 6.  You perform a test-cross with a plant heterozygous for all three mutations and obtain the following segregation pattern                                                  Phenotype                       No. of Progeny              Green leaves, yellow silk, normal plant               384             Green leaves, yellow silk, pigmy plant                   1             Green leaves, salmon silk, normal plant              71             Green leaves, salmon silk, pigmy plant                40             Purple leaves, yellow silk, normal plant               36             Purple leaves, yellow silk, pigmy plant                75             Purple leaves, salmon silk, normal plant               3             Purple leaves, salmon silk, pigmy plant               390                                                                                Total = 1000 Use this information provide a map that shows the order of these genes and the distance between them (i.e., gene 1 – XcM – gene 2 – X cM – gene 3) and calculate the interference for this region.
