Consider the results in this table, where a testcross produces non-crossover phenotypes 94.44% of the time, single crossover between y and w 1.5% of the time, and single crossover between w and ec 4% of the time. What is the expected percentage of the time (frequency) that a double crossover between both w – ec and between y – w will occur?

If you set up a dihybrid cross between plants with 2 pairs of contrasting characteristics that are not sex-linked and for which there is independent assortment [tall (D)/dwarf (d) & red flowers (W)/white flowers (w)], where the parents are true breeding [Parent 1 = tall,red (DDWW) Parent 2 = short,white (ddww)], and all of the resulting F1 offspring are tall with red flowers, what proportions of the different possible genotypes would you expect in F2 offspring?
