12. A pink-flowered petunia with round leaves is crossed with a blue-flowered petunia with heart-shaped leaves and all of the F1 progeny have blue flowers and round leaves. One of the F1 plants is crossed to a pink-flowered petunia with heart-shaped leaves. Out of the 200 F2 progeny from this cross, the following phenotypes are observed: 60 Blue-flowered, heart-shaped leaves 2 40 Blue-flowered, round leaves 40 Pink-flowered, heart-shaped leaves 60 Pink-flowered, round leaves ล์: [2 pts] which F2 phenotypes are parental? L and I shape in the Petunia genome? Please use the chi square table (at the end of the exam 15 pts] What are the relative positions of the genes controlling flower color and leaf handout) to explain your answer.
