The aim of this review is to summarize the existing data collected in high-resolution phylogenetic studies of mitochondrial DNA and Y chromosome variation in mainland and insular Croatian populations. Mitochondrial DNA polymorphisms were explored in 721 individuals by sequencing mtDNA HVS-1 region and screening a selection of 24 restriction fragment length polymorphisms (RFLPs), diagnostic for main Eurasian mtDNA haplogroups. Whereas Y chromosome variation was analyzed in 451 men by using 19 single nucleotide polymorphism (SNP)/indel and 8 short tandem repeat (STR) loci. The phylogeography of mtDNA and Y chromosome variants of Croatians can be adequately explained within typical European maternal and paternal genetic landscape, with the exception of mtDNA haplogroup F and Y-chromosomal haplogroup P* which indicate a connection to Asian populations. Similar to other European and Near Eastern populations, the most frequent mtDNA haplogroups in Croatians were H (41.1%), U5 (10.3%), and J (9.7%). The most frequent Y chromosomal haplogroups in Croatians, I-P37 (41.7%) and R1a-SRY1532 (25%), as well as the observed structuring of Y chromosomal variance reveal a clearly evident Slavic component in the paternal gene pool of contemporary Croatian men. Even though each population and groups of populations are well characterized by maternal and paternal haplogroup distribution, it is important to keep in mind that linking phylogeography of various haplogroups with known historic and prehistoric scenarios should be cautiously performed.

No real surprises in this paper.

  1. The most frequent Y chromosomal haplogroups in Croatians, I-P37 (41.7%) and R1a-SRY1532 (25%), as well as the observed structuring of Y chromosomal variance reveal a clearly evident Slavic component in the paternal gene pool of contemporary Croatian men.

    I don’t know why would I2a(P37) imply any kind of “Slavic component” at all. It’s a clade that is concentrated in the Balcans precisely and rare or totally absent among Northern Slavs. Its significative presence along the Mediterranean (Italy, France, Spain) actually probably means it was present in the time of Cardium Pottery expansion and that, in any case, it’s not any “new” arrival from further north.

    Guess that R1a1 can be argued as Slavic (though is also dominant in Uttar Pradesh or Tajikistan, for instance) but is normally considered Indoeuropean in general and not specifically Slavic.

  2. I2a is not significantly found along the Mediterranean countries such as Italy, France and Spain as you have assumed.

  3. I2a is not Slavic at all.

  4. I2a is not Slavic,it represents indigenous populations of western Balkans-the Illyrians,who were romanized at that time,so that I2a is often called ‘Illyro-Roman’ haplotype.
    Outside Croatia and Bosnia-Herzegovina,it is most frequent in Moldavia,non-Slavic country.Moldovans belong to the group of East Latin people.
    One way or another,I2a is surely not Slavic.

  5. I2a is not Slavic,it is called the ‘Illyro-Roman’ factor,carried by the indigenous romanized Illyrian population of Croatia.

  6. I2a is not Slavic,it is Illyrian

    Hey hey,
    We thank the Lord All-Mighty for the knowledge that He has bestowed upon us through these gene studies. Firstly, no frign body from the historians or anthropologists or archaeologists can tell us exactly what slav is, who slav is, where slav is, where slav came from, etc. They have assertions but assertions are not fact. Once they say, slavs are asiatic, one they are indo-european, others who have sense say there is no such thing as a slav race or nation which is the correct view. In all the illyrian languages, serbian croatian bosnian mntgerian slovenian chech russ etc, all these languages have their origin in the balkans as per the majority view of linguists. In these languages the call the germans njemci meaning dumb, silent, while the goths old germans used to call the illyrians slawan, meaning dumb\silent. our genes are original and have spread through europe by military expansion when illyrian soldiers were sent all over the roman and later byzantine empire. Moldova was a border line of the roman empire. Illyrian troops fought against germanic tribes under roman legions, in the north leaving the I gene factor. When the Muslims conquered spain, the arab historians say that the saqaaliba or as the german scholars say slavs, from todays dinaric alps were brought by the western roman emperor to fight the arabs to no avail. They lost, spain was muslim for 800 years and these warriors from the dinaric alps became muslims and were of the elite guard, bringing their I2a genes with them to spain, any notion that albanians\arnauts\shiptars, God knows what other titles they have, are Illyrians, is the same as saying that a chiwawa is a cat. albanians are a hybrid mixture of at least ten races, and all you have to be is not blind, look at their faces and see that they are foreigners. Shiptar is arabic for jelous man, arnaut is arabic for its a disgrace for us to return, and turkish for they have not returned to their land. And albanian, it was given to the by the germans, so that they dont join jugoslavia. Their genes are 46% E3b which is mostly found in marocco 88% and J which is turkish and arabic in origin. We have to just compare dna, history and anthropology together and walla…

  8. So illyrians were slavs?but to me that just doesn’t make sense.

  9. No such thing as Slavs, nor can our beloved historians agree on who they are or where they are from and how all these countries that are Slavic have similar languages yet are different anthropologically and genetically etc..
