A particular species of plant can be tall (D) or dwarf (d). Flowers can be either purple (G) or white (g). And, leaves can be smooth (H) or rough (h). All capital alleles are dominant to lower case alleles. The genes D/d and G/g reside on the same chromosome 26 cM apart. H/h, resides on a different chromosome. A pure-breeding tall, white, and smooth plant (DDggHH) is crossed to a pure-breeding dwarf, purple, and rough plant (ddGGhh). The F1 progeny are then test crossed. What proportion of the offspring from the test cross will be tall, purple, and smooth? Enter your answer in the format 0.111 (include a zero before the decimal and three numbers after the decimal).
