Not really, because it doesn't guarantee any specific individual in that population has any of the populations likely traits, it's only useful in aggregate for things like prioritising screening for certain genetic conditions for people of particular back ground. It's useless to determine if someone will be an excellent sprinter or a fighter pilot because ultimately you still have to test every individual anyhow and it doesn't really tell you anything about the "tree" of human evolution which is really a bunch of thick branches all tightly fused together into an indistinguishable single branch.
