In flies dumpy wings and ebony bodies are each mutations recessive to wild type, and you expect them to behave in a Mendelian fashion. A dihybrid cross between two animals, each heterozygous for dumpy wings and ebony bodies (DdEe X DdEe) is performed with the following results:

Wild type wings; wild type body 473
Wild type wings; ebony body 156
Dumpy wings; wild type body 149
Dumpy wings; ebony body 52

You will ultimately explain these results using a Chi-squared test.
(a) Begin by setting up a Punnett Square to predict the phenotypic classes and ratios. Use the results of the Punnett square to form a hypothesis on phenotypic ratios.
(b) Perform the chi-squared analysis. Show work.
(c) What conclusion can be drawn from this analysis?
