You would like to know whether the progeny of a pair of mated fruit flies are distributed among the resulting four phenotypic classes in a 1:1:1:1 ratio. You perform a chi-square test and obtain a p value of 0.04. Assuming you have done the test correctly, select the best interpretation of this result. a. The phenotypic ratio is actually 9:3:3:1 b. Approximately 4% of the offspring lie outside the range of values expected for a 1:1:1:1 ratio. c. The differences between the observed and expected counts are too large to be attributed to chance. d. The traits being studied are on separate chromosomes.
