The endosperm of maize can either be yellow or white. This endosperm color is governed by a gene 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. 2.

The C gene comes in multiple alleles. C is colored and allows the aleurone to be colored in the
kernels (if the Rallele is in the genotype). The c allele is uncolored and does not allow the aleurone to
have a color (even in the presence of the R allele), so the color of the endosperm shows through
(yellow or white). The C' allele is a color inhibitor that also inhibits the color of the aleurone (even in
the presence of the R allele). C' is dominant over C. C is dominant over c. A true-breeding strain with
the color inhibitor (yellow) and with starchy kernels was crossed to a true breeding strain colored
(purple) strain with sweet kernels. The F1 were yellow and starchy. They were selfed (crossed to
themselves) 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.
