Quite right, in theory and at least sometimes in practice. I often see the
phrase hierarchical testing in research articles, where large numbers of samples
are typed at the same time. I don't know the practicalities of hierarchical
testing for small batches though, in the quantity that FTDNA might be running.
You'd have to type one marker, wait for results, decide which marker to
amplify next, type it, wait for results... and there would be lots of customized
handling for each sample.
