What can I expect on an R Deep Clade test? Does FT test SNP's only back to R to confirm what they have predicted, in my case R1b1b2 ? Or do they continue testing as far as they can go down the branches ? And if so is it possible that beyond M269 if I test negative for L23 L49 that I stay at R1b1b2 ? Do some people deadend here,i.e. their branch has no further mutations ? Or is it a case of as yet undiscovered SNP's ? What prompts the discovery of new SNP's ? Some branches are much more developed than others. Is it a matter of personal involvement, does the market play a part in this ? I imagine since so many of European descent are looking for answers and are willing to pay for SNP's that this is where the business is. Or are there also funded university projects ?
When you order deep SNP testing, FTDNA will look at your haplotype and estimate what your haplogroup probably is, then design a testing strategy that will determine your haplogroup using the fewest possible tests, to keep the price down. If you are deduced to be R1b1b2, they will likely begin the testing with M269. http://dgmweb.net/DNA/SNPcharts/R1b_2010-02-12.shtml If you are positive for M269, there is no point in wasting money on testing the upstream SNPs. A deep SNP test will always include the newest SNPs that are relevant to you, as deep as they can go. If you are M269+, but L23-/L49-, you will be declared R1b1b2*. And, yes, some have that result, and some are R1b1*, and so on. It indicates they retain the ancestral condition, rather than possessing any of the subsequent mutations. There are lots of undiscovered SNPs and the search for them is intense and ongoing, especially in Haplogroup R1b. It's expensive research, partly driven by the market place and partly driven by academe, that is, some of the research is being done at commercial labs and some is grant funded at universities. Most of the scientists in commercial labs have strong academic ties, and you will find them as authors of papers in scientific journals.

Most 'Deep Clade' Tests aren't worth the money. Most haplogroups and subclades can be accurately determined with enough STR markers. The more STR testing the better. For example, if DYS 455 is 8, then the person is overwhelmingly likely to be haplogroup I1.
