You will have to be more specific by what you mean by "they". Trace Genetics only does a broad general "world - wide" SNP test of basic markers. FTDNA will only test certain markers such as P25. Thus they do not test for the downstream M269 or the nine markers known to exist below M269. As to R1a, they used to test SRY10831.2 (R1a) although I and others have repeatedly noted that M17 is a more useful marker (R1a1). They may now be using this marker (M17) but I have yet to see anyone with M17 results. They have no plans I know of to change the status quo. They have indicated that they may offer a super I haplogroup test (which is why others have decided to hold off on developing this "multi - clade" type of testing for haplogroup I). There will soon be many more options for haplogroup testing.
