The Team as independent volunteers cannot carry out research on relations in individual kit family lineages (genealogical time, private and historical haplogroups, nearest matches) in this large project which includes the entire old J2 haplogroup and many thousands of participating kits/samples.

Learn & Discuss Goals

  • Resource to gain a clearer picture about the history and nature of the fascinating Y-DNA haplogroup J2 (J-M172), and especially, its sub-clade structure and the geographical dispersion and distribution of ethnic groups among the clades.
  • Discover where a kit/sampe/lineage fits into the big family tree of J2 and find new defining SNPs. Updated versions of the haplogroup tree can only be kept by automatic systems and possibly refined trough manual research by combining data. Since 2019 only done in subprojects with less total members.
  • Increase participation in countries (and ancestry places) with few NextGenSeq J2 results to find more informative clusters in historical time: Turkey, Armenia, Georgia, Azerbaijan, Russia (North Caucasus, Murmansk), Iran, Iraq, Lebanon, Syria, Israel, Jordan, Saudi Arabia, Bahrain, UAE, Oman, Yemen, Egypt, Sudan, Eritrea, Ethiopia, Somalia, Libya, Tunisia, Algeria, Morocco, Greece, Balkans, Italy, Austria, France, Turkmenistan, Uzbekistan, Afghanistan, Tajikistan, Kyrgyzstan, Kazakhstan, Pakistan, India, Sri Lanka, China (Tibet), Vietnam, Indonesia, Madagascar.
