There is new research article, "R1a frequency, subclades and origin of Croats and South Slavs" (PDF at Academia.edu).
In the Eupedia's article Haplogroup R1a (Y-DNA) are made several outdated and erroneous claims:
- There exist regional disparities, but they are more local and not so much on national how much on general Southwestern vs Southeastern level.
- In all, aside Bulgarian, South Slavic nations the R-CTS1211 makes the majority of R1a. In some it is a predominant clade (up to 80% share).
- Bosnian and Herzegovinian and especially Serbian R1a or R-CTS1211 does not belong at all for the most part to I-L1280>Y5647. This information must have been extracted from a very limited, biased and old data. It reaches high concentration only in the population of Tuzla (Northeastern Bosnia). Generally in Bosnia and Herzegovina probably makes one of the most frequent subclades, but is needed further sampling of regions and ethnic groups in Bosnia and Herzegovina. None of 5 Herzegovinian Croat samples belonged to it. Population of Serbia does not have the most frequent subclade but several with similar or same percentages, and in the Western Balkans Serbs the I-L1280>Y5647 was zero. R-L1029 makes the vast majority of R-M458. R-Y4459 is not specific for these two nations neither in such percentages to be specifically noted among others as exist subclades with higher percentage (R-Y2613, R-Y2902, YP953, YP4278...).
- Croatian R1a or R-CTS1211 is not almost exlusively & for the most part R-Y2613>Y2608 at all. It is the second (c. 25%) most frequent subclade after R-Y2902 (27%), followed by R-YP343 (mostly YP371 not P278.2) and R-L1280 (peaks in Central and Eastern Croatia) which all together make 75-85% of their R-CTS1211.
- I-L1280>Y5647's sample location among West and East Slavs and South Slavs shows it is at least partly Southeastern Slavic subclade (with another high peak in Romania) which partly or mostly migrated along Eastern Carpathians to the Eastern Balkans and not only via Poland-Hungary.
- Croatian lineages, including R-Y2613, mainly expanded from the Western Ukraine and Southeastern Poland (Eastern Carpathians) through Pannonia (Hungary) not via Moravian Gate.
