Question

In peas, the dominant seed shape is round and the recessive iswrinkled(w). The dominant trait for pod color is green andrecessive is yellow (y). A plant with round seeds and green podsthat i heterozygous only for the color trait is crossed with aplant that has wrinkled seeds and yellow pods, and the resulting F1progeny are selfed(self fertilized).
Write out the P1 genotpes and the F1 and F2 genotypic andphenotypic ratios.

What proportion of the plants with green pods and round seeds fromthe F2 generation would you expect to be true breeding(i.e. produceonly plants with green pods and round seeds)?
