Studies of the regions of Y chromosome that are inherited together (haplogroups), reveal ヨーロッパ has four population groups, namely R1b-M269, I1-M253, I2-M438 and R1a-M420, pointing to four distinct paternal origins. R1b-M269 group is the most common group that ウェールズ、アイルランド、イングランド、ドイツ、スペイン、オランダ、フランス、ポーランドの国々に存在しますが、 I1-M253 has its origins in Northern ヨーロッパ and is predominantly found today in countries of Sweden, Finland, Denmark, Iceland, and Norway. I2-M438 has its origins in Southern and Eastern and is predominantly found today in Sicily, Celtec, Bosnia, Herzegovina and Switzerland. The R1a-M420 group has its origins in Eurasia and South West Asia around 25000 years ago. Another genetically distinct population group is of Roma people belonging to haplogroup H1a1a-M82, has its origins in the north-western region of the Indian sub-continent
欧州言語 continent has seen a number of infightings and migrations. With the result, the continent has been described as turning into a melting pot with populations of various origins and cultures living and thriving together. In order to understand the paternal origins of the populations living in ヨーロッパ 今日、勉強することは役に立ちます Y染色体 variability and how it contributes to the distribution and development of male 遺伝子の pool. Studies on the polymorphism of the Y chromosome show the presence of four major haplogroups, namely R1b-M269, I1-M253, I2-M438 and R1a-M4201.
R1b-M269グループは、フランスとスペインのバスク地方で約4000〜10000年前に発生した最も一般的なグループです。2 and is present in ~110 million 欧州言語 men. It is present in countries of Wales, Ireland, England, Germany, Spain, Netherlands, France and Poland and increases in frequency on an east to west gradient, its prevalence in Poland at 22.7%, compared to Wales at 92.3%. Interestingly, this haplotype has been associated with different European colonisations, mainly in several American countries.
I1-M253 has its origins in Northern ヨーロッパ around 5070 years ago and is predominantly found today in countries of Sweden, Finland, Denmark, Iceland, Norway.
I2-M438 has its origins in Southern and Eastern ヨーロッパ around 33000 years ago and is predominantly found today in Sicily, Celtec, Bosnia, Herzegovina and Switzerland.
R1a-M420 has its origins in Eurasia and South West Asia around 25000 years ago, and is currently found in populations extending from Scandinavia and Central ヨーロッパ to southern Siberia and South Asia.
別の 欧州言語 population group with haplogroup on Y chromosome of H1a1a-M823現在、ルーマニア、ブルガリア、ハンガリーなどの東ヨーロッパと中央ヨーロッパの地域に集中している10万〜12万人の人口は、インド亜大陸の北西部に起源があります。 これらの人々はローマとして知られています4 人。
Thus, in spite of migrations, 欧州言語 population comes across as having these 遺伝 distinct groups based on haplotypes, that have maintained their paternal identity.
