In a certain plant, the orange flower allele (Y) is dominant to the yellow flower allele (y). An allele that prevents flower color pigment formation (W) results in white flowers irrespectively of the Y and y alleles, and is dominant to an allele (w) that allows flower color formation. What is the expected proportion of phenotypes in the offspring of a cross between two dihybrid white-flower plants?   1/3 white flowers, 1/3 orange flowers, 1/3 yellow flowers 9/16 white flowers, 3/16 orange flowers, 3/16 yellow flowers, 1/16 orange-yellowish flowers 12/16 white flowers, 3/16 orange flowers, 1/16 yellow flowers 6/8 white flowers, 1/8 orange flowers, 1/8 yellow flowers 1/2 white flowers, 1/4 orange flowers, 1/4 yellow flowers
