#2 a) If sex and eye colored were viewed as two different phenotypes with male being dominant over female (or vice versa), then Mendelian ratios of a dihybrid cross may explain the ratios that Morgan got. Here is some hypothetical data based on the ratios gotten by Morgan and the expected Mendelian ratios for a dihybrid F1 cross. Perform a Chi-square test (separate scrap paper) with the null hypothesis being that the "Morgan observed ratios" are within chance from the Mendelian ratios. State whether the Chi-square test supports or rejects the null hypothesis and explain. (Be sure to include the X2 value, degrees of freedom, critical value.) Hint: what did Morgan discover? Think about this for your degrees of freedom.

Expert Solution
Step 1

Chi-square test is performed to test if there is any association between two variables.

 The null hypothesis states that the association between the "Morgan observed ratios" and the "Mendelian expected ratios" are only by chance.
