In maize, overall kernel color is controlled by both the endosperm and the aleurone colors. the endosperm color is yellow when the allele y is present. in the homozygous recessive (yy) condition the endosperm is white. the y alleles are masked by the presence of a colored aleurone. the r and p genes control the aleurone color. the allele p interacts with the r allele to produce a purple color, whereas in the recessive condition (pp), the gene interacts with the r allele to produce a red color. if the r allele is present in the homozygous recessive state (rr) then the aleurone will be colorless, allowing the endosperm color to be expressed. two fully heterozygous individuals are crossed. give the phenotypes, and frequency of occurrence, of the f2 offspring.
