2. The endosperm of maize can either be yellow of White. with two alleles, Y has yellow endosperm and y has white endosperm. However, this endosperm color is masked when the aleurone is colored purple. A true-breeding maize line with the color inhibitor and yellow endosperm (C'C'YY) (so they were yellow) was crossed to a true-breeding line with purple aleurone (and white endosperm) (CCyy). The F1 were crossed and 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.
