10. This problem is a little more challenging than the previous ones because it involves lack of dominance in both characteristics that are being followed. However, you use the same Punnett square method to determine the
outcome of this cross as you would with any other double-factor cross.
In the radish plant, the long and round traits exhibit lack of dominance and the heterozygotes have an oval
shape. The red and white color traits also exhibit lack of dominance and heterozygotes have a purple color. Two
oval-shaped, purple plants are crossed. What phenotypic ratio would the offspring show?
