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.

HELP!! I ATTACHED INCORRECT ANSWERS AS A SEPERATE SCREENSHOT 

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:
Part B
Calculate the chi-square value for hypothesis of interactic
of two epistatic genes.
