apple group j was created in western
asia 42
900 years ago and its direct descendants
j-1 and j-2 are estimated to have formed
in the vicinity of j-31
600 years ago
the j2 is also referred to as the jm 172
the age of haplogroup j is at the
midpoint of the ages of representative y
dna haplogroups
in the last episode i introduced the
current distribution and celebrities of
the half group j1 phylogenetic trees and
the ancient y dna with j1
in this video i will introduce j2
[Music]
first let's map the distribution of
today's ydna haplogroup j2
this map was prepared concerning
eupedia's data
for j2 high rates are observed in people
living in the caucasus
why dnar j and g are mainly observed in
the caucasus region
people living in this area with high
j-2s are in gush chechens azeri
georgians abkhazians and qmex
four other haplogroups please refer to
the table on the screen
if you look at j2m the most observed
regions outside the caucasus crete 34
cypress
28.5
lebanon 26 anatolia 24 greece sicily and
iran 23
are observed
it is followed by iraq syria palestine
and saudi arabia
[Music]
it is also observed to be relatively
high among jews
ashkenazi jews are 19
and sephardic jews are 25
another 24.5 percent of latch belong to
the j2 group
celebrities belonging to jay to include
american actors ben affleck and adam
sandler
matt lauer who hosted nbc's today from
1997 to 2017 is also known to have lost
to why dna haplogroup j2
american politician bernie sanders was j
tua
now let's map the area where ancient y
dna j2 was found
before 3000 bce it is indicated by a red
dot and between 2999
and 2000 bce is characterized by a blue
dot
the pink dots represent j2 between 1900
bc and zero
one c and later are marked with black
dots
the labels that pop up on the screen are
the smps of y dna j2 an introduction to
ancient y dna j2 is followed by an
introduction to the phyllogenetic tree
of j2
[Music]
so
[Music]
let's display the phylogenetic trees of
j2m
172 on the screen
the box contains the supplied and snp
information of haplogroup
the information just below the box shows
the most likely time of formation and
the time to a most recent common
ancestor
red boxes indicate main subclades
in addition the region where the smp is
believed to have appeared first is
indicated in the white text above the
box
ciclades
pf5116 and j2 bytes m 102 will be
described separately and immediately
following
[Music]
now let's take a look at the supplades
of the pf5160
do
[Music]
now let's look at the suplades of j2
bytes m102
[Music]
so far
we have investigated the distribution of
ydna haplogroup j2m 172 in each country
and the ancient y dna j2 and
simplicative j2
see you with a better video in another
episode
