In a particular kind of wildflower, the wild-type flower color is deep purple, and the plants are true-breeding. In one true-breeding mutant stock, the flowers have a reduced pigmentation, resulting in a lavender color. In a different true-breeding mutant stock, the flowers have no pigmentation and are thus white. When a lavender-flowered plant from the first mutant stock was crossed to a whiteflowered plant from the second mutant stock, all the F1 plants had purple flowers. When the F1 plants were allowed to self-fertilize, the following F2 generation was observed: 157 purple 71 white 49 lavender 277 total A. Using your own clearly defined genetic symbols, together with their phenotypic effects, give the appropriate P0, F1 and F2 genotypes to explain these results. Is this trait controlled by the alleles of a single gene? B. What phenotypic ratio would be expected from a testcross with an F1 wildflower? C. What kinds of progeny (phenotypic ratios) would you expect if lavender F2 plants were allowed to self-fertilize?
