Dr. Ara B. Dopsis and Dr. C. Ellie Gans are performing genetic crosses on daisy plants. They self-fertilize a blueflowered daisy and grow 100 progeny plants that consist of 55 blue-flowered plants, 22 purple-flowered plants, and 23 white-flowered plants. Dr. Dopsis believes this is the result of segregation of two alleles at one locus and that the progeny ratio is 1:2:1. Dr. Gans thinks the progeny phenotypes are the result of two epistatic genes and that the ratio is 9:3:4.The two scientists ask you to resolve their conflict by performing chi-square analysis on the data for both proposed genetic mechanisms:
1) Calculate the chi-square value for hypothesis of segregation of two alleles at one locus.
2) Calculate the chi-square value for hypothesis of interaction of two epistatic genes.
