In corn, the genes Pl for purple leaves (dominant over pl for green leaves), 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.
