The appearance of the mature dry kernel of maize

Many different genes influence the appearance of the mature dry kernel of maize. Ears of corn containing plump kernels are controlled by a gene called sugary, Su. The Su gene codes for an enzyme known as the starch debranching enzyme. When this gene is in the homozygous recessive condition, less sugars are polymerized into starch resulting in sweeter tasting corn. In addition, this low starch kernel loses more moisture during the drying period and therefore shrivels more than the high starch kernel produced when a dominant allele of Su is present. A true-breeding colored aleurone, starchy endosperm maize line was crossed to a true-breeding yellow aleurone, sugary endosperm maize line. The resulting ears contained kernels with only colored aleurone and the starchy endosperm. The F1 kernels were grown and the plants were crossed to each other. You have been given the results of this cross. What is your proposed phenotypic and genotypic ratio for the offspring (kernels) of this cross? Perform a Chi-square to prove or disprove this ratio
