An individual expressing the dominant phenotypes for kernel color and texture could have one of four different genotypes. For each potential genotype, determine the expected frequency of each phenotypic combination which would be observed following a testcross.

Follow-up Question

Using the numbers provided in the attached image for the observed progeny counted for the testcross shown in the question above, perform a Chi-square analysis to determine whether you are correct as to the genotype of the unknown individual. Be sure to include a properly phrased hypothesis, the degrees of freedom, a complete Chi-square table, the Chi-square value, p-value range, and your determination of whether your hypothesis was correct.
