Population diversity tests (multi-strain drift test, X-gal test to distinguish lager from ale yeast)
Yeast populations can be subject to genetic drift and mutation. There are a variety of tests we can do to determine the extent of diversification and determine whether it is worth isolating a new individual to start a new population with. Two tests are the multi-strain drift test that distinguishes strains with WLN media and the X-gal test can distinguish lager from ale yeast.
