IJ Haplogroup is a descendant
branch of
Haplogroup IJK which in turn derives from the greater
Haplogroup F. Descendants are
Haplogroup I and
Haplogroup J. Haplogroup IJ derived populations account for a significant
fraction of the present-day populations of Western Eurasia, North Africa, the
Americas, and Australia.
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.

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
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

J2a1 (DYS413≤18)
J2a2 (M340)
J2b (M12, M314, M221)
J2b*
J2b1 (M102) Mainly found in the Balkans, Greece, and Italy
(possibly from Ancient Greeks)
