What does L21+ mean?
It is the most common Y chromosome subclade of paternal lineages in the British Isles and is also significant in France. It is found across Western and Central Europe as well as Scandinavia. Other names for L21+ are M529+, S145+. Other SNPs that are equivalent to L21+ are L459+, FGC3218+.
What is the R1b-L21 project?
An important role of the project is to support DNA testing steps that will help identify where you fit within R1b-L21. This may lead you to one of the large subclade of L21 projects, which are highly recommended.
How old is L226?
L226 is a ‘private’ marker found in Kevin O’Brien and his immediate family (perhaps back 100-500 years). L226 is a defining marker for the Irish Type III cluster and appears in no other clusters. (so perhaps 800 -1,200 years old) L226 is downstream of L21 but occurs more generally, across several clusters.
What SNPs are equivalent to L21+?
Other names for L21+ are M529+, S145+. Other SNPs that are equivalent to L21+ are L459+, FGC3218+. Recently we’ve discovered that Z245, Z260 and Z290 are equivalent to each other but slightly older than L21 so Z290+ people are also included.
