No. It all depends on how many mutations there are on other markers.
If, in fact, there is only one mutation in evidence, then it doesn't
matter which marker it was. As you pile on more mutations, then it
begins to matter, but you also quickly reach a state where the two
testees are probably not related anyhow.
