IJ Haplogroup

Haplogroup IJ Y-chromosome has not been found among any modern human population; the existence of the Haplogroup IJ node has been inferred from the fact that certain mutations are shared in common among all Y-chromosomes belonging to the descendant Haplogroups I and J.

Subclades of IJ

• I (M170, P19, M258, P38, P212, U179) Haplogroup I notation updated to ISOGG 2008
  • I*
  • I1 (M253, M307, M450/S109, P30, P40, S62, S63, S64, S65, S66, S107, S108, S110, S111) (formerly I1a) Typical of populations of Scandinavia and Northwest Europe, with a moderate distribution throughout Eastern Europe
    • I1*
    • I1a (M21) (formerly I1a2)
    • I1b (M227) (formerly I1a1) Appears to be limited to a marginally low frequency of approximately 1% among Slavic and Uralic peoples of Eastern Europe; also detected in a single Lebanese man
      • I1b1 (M72) (formerly I1a1a)
    • I1c (P109)
    • I1d (P259)
  • I2 (M438/P215/S31) (formerly I1b)
    • I2*
    • I2a (P37.2) (formerly I1b1) Typical of the South Slavic peoples of the Balkans, especially the populations of Bosnia, Croatia and Serbia ; also found with high haplotype diversity values, but lower overall frequency, among the West Slavic populations of Slovakia and the Czech Republic; a node of elevated frequency in Moldavia correlates with that observed for Haplogroup I2a (but not for Haplogroup I1)
      • I2a*
      • I2a1 (M423)
        • I2a1*
        • I2a1a (P41.2/M359.2) (formerly I1b1a)
      • I2a2 (M26) (formerly I1b1b) Typical of the population of the so-called "archaic zone" of Sardinia; also found at low frequencies among populations of Southwest Europe, particularly in Castile, Béarn, and the Basque Country
        • I2a2*
        • I2a2a (M161) (formerly I1b1b1)
    • I2b (M436/P214/S33, P216/S30, P217/S23, P218/S32) (formerly I1b2)
      • I2b*
      • I2b1 (M223, P219/S24, P220/S119, P221/S120, P222/U250/S118, P223/S117) (formerly I1b2a - old I1c) Occurs at a moderate frequency among populations of Northwest Europe, with a peak frequency in the region of Lower Saxony in central Germany; minor offshoots appear in Moldavia and Russia
        • I2b1*
        • I2b1a (M284) (formerly I1b2a1) Generally limited to a low frequency in Great Britain
        • I2b1b (M379) (formerly I1b2a2)
        • I2b1c (P78) (formerly I1b2a3)
        • I2b1d (P95) (formerly I1b2a4)
• J (12f2.1, M304, S6, S34, S35)
  • • J*
    • J1 (M267) Typical of populations of the Middle East, Dagestan and Semitic-speaking populations of North Africa and East Africa
      • J1*
      • J1a (M62)
      • J1b (M365)
      • J1c (M367, M368)
      • J1d (M369)
      • J1e (M390)
    • J2 (M172) Typical of populations of Mesopotamia, Anatolia, Southern Europe, and the Caucasus, with a moderate distribution throughout Southwest Asia, Central Asia, South Asia, and North Africa
      • J2*
      • J2a (M410)
        • J2a*
        • J2a1 (DYS413≤18)
        • J2a2 (M340)
      • J2b (M12, M314, M221)
        • J2b*
        • J2b1 (M102) Mainly found in the Balkans, Greece, and Italy (possibly from Ancient Greeks)
