in lentils, a single gene with multiple alleles controls seed coat pattern. in a cross between a true-breeding speckled lentil and a true-breeding blotched lentil, all of the f1 progeny had seeds that were speckled and blotched (i.e. every seed had both distinguishable speckles and blotches). if you were to cross two of the f1 spotted/dotted plants, what phenotypic ratio would you expect in the f2 generation?
