For a given trihybrid cross (looking at three different genes), you want to calculate the chi-square value to establish possible linkage. How many degrees of freedom would you use to determine the p value?

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.

Experimental Insight 2.1 describes data on the kernel color distribution of bicolor corn, collected by a genetics class like yours. To test the hypothesis that the kernel color of bicolor corn is the result of the segregation of two alleles at a single genetic locus, the class counted 9882 kernels and found that 7506 were yellow and 2376 were white. Use chi-square analysis to evaluate the fit between the segregation hypothesis and the class results.
