Question

You are a researcher examining the expression pattern of a wobbly fly phenotype. You have flies that fly straight and those having a wobble flight. When you cross a straight flying strain with a strain showing a wobble flight, all the F1 flies fly straight. In the F2 generation, you get 762 straight flying flies and 238 wobbly flies. Your null hypothesis is that one gene controls flight patterns and that straight is dominant to wobbly. Use chi square analysis to test your hypothesis.

(a) What is your chi square number? Submit your answer as it is.

(b) Do you reject or fail to reject the null hypothesis?

Explanation / Answer

Answer

Applying Chi square analysis.

Hence Here are following outcomes:-

Part (a)

Chi square = 0.768

Part (b)

Failed to reject Null Hypothesis.
