If the phenotype of pea pod color is determined by incomplete dominance and the combination of an allele for yellow seeds and an allele for green seeds yields blue seeds, you would expect the f2 generation from an original cross of true-breeding green stock with true-breeding yellow stock to be:

The result would be twenty-five percent yellow and the blue ones will be fifty percent while green is twenty-five percent. If an F2 generation is derived from the two true-breeding parents which have the same trait for different characteristics. The recessive phenotype would be hundred percent of true breeding if they fertilized themselves. A recessive trait is expressed when the genotype is only homozygous recessive.
