Which of the following is usually true of a chi-square test performed when deciding whether two genes are linked?
A) the p-value is 2
B) degrees of freedom (df)= 2
C) the minimum sample size is 1000
D) the null hypothesis is that the loci are not linked
E) degrees of freedom (df)= 4

The null hypothesis for a chi-square test for linkage is that the loci are not linked. The p-value and degrees of freedom will depend on the specific test and sample size, and there is no minimum sample size requirement. Choice A (p-value of 2) and Choice E (df = 4) are incorrect as they do not make sense in the context of a chi-square test for linkage.
