Show transcribed image text Most flour beetles are black, but several color variants are known. Crosses of pure-breeding parents produced the following results in the F_1 generation, and intercrossing the F_1 from each cross gave the ratios shown for the F_2 generation. The phenotypes are abbreviated Br, black; Br, brown; Y, yellow; and W, white. From these results deduce and explain the inheritance of these colors. Write the genotypes of each of the parents, the F_1, and the F_2 in all crosses.
