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. (Remember Purple: PP, Smooth: SS, Yellow: pp, Wrinkled: ss)
An individual expressing the dominant
Step by step
Solved in 3 steps
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.
Based upon the attached image and your answer above, what is the genotype of the unknown individual? Please explain your answer. (The attached image is the results of the test cross from the question above).
