Three samples of Drosophila heterozygous for the recessive genes black body (b) and rough eyes (r) were inbred and the following data were obtained.
A. perform a chi-square analysis for each sample assuming a 9:3:3:1 distribution.
B. Is there a significant deviation in any of these samples?
Use the table attached.
This solution shows a step-by-step calculation to conduct a chi-square analysis on the distribution of the recessive genes of black body and rough eyes. It calculates the chi-square statistic and comparing it to the p-value to make a decision to accept or reject the null hypothesis.
