Radish flowers may be red, purple, or white. The part of the radish we eat may be oval or long. A cross between a red-flowered long radish plant and a white-flowered oval radish plant yields all-purple long radish offspring. Then the F1 are crossed. In the resulting F2 generation, which of the following phenotypic ratios would be expected? 1) 9:3:3:1 2) 9:4:3 3) 1:1:1:1 4) 1:1:1:1:1:1 5) 6:3:3:2:1:1

Assume the color of rose petals are an incomplete dominant trait. The red color allele (R) is dominant over the white color allele (r). What would be the phenotypic ratios in a cross between two heterozygous red colored roses?
