Molecular biologists have demonstrated that there is preferential switching to the opposite mating type in budding yeast. Switching from a$\rightarrow$a (or $\alpha$ $\rightarrow$$\alpha$) with no change in mating type occurs rarely. Since the DNA sequence in the MATa locus would be the same as the donor HMRa, how would you show that a$\rightarrow$a had occurred or not?
