G-L30

This is the home page for men who are L30 or only predicted L30. 

Most men listed in G Project Roster are merely men without enough testing
to determine their L30 subgroup.  Their marker values suggest they are within
L30.  It is only L30 men and their subgroups which have a 14 value for marker
DYS425, and that is a good guide for identifying DYS425 men.  Additional testing
to determine exact subgroup within L30 is always helpful.  So far, only one man
has been found to have L30 and simultaneously be negative for the two L30 
subgroups.

                             L30
 
The above diagram shows the position of L30 in the haplogroup G tree.   Note
that it has sister group PF3146.  Men can only belong to one of these 
two subgroups because each has a different ancestor.

L30 is a more recent mutation than L1259 & P15 which is L30's mother groups.  They
include more men than just L30.  There is some additional information about
the totality of P15 men on the left in the G-P15 tab.  But P15's mother group, P287
has the most information at G-P287.   And finally the mother group of all G men
is explained in G-M201.  All G men have the M201 mutation which is the oldest 
of all. 

L30 encompasses most of the G persons in Europe though virtually all fall
within its subgroups.

L30 has two subgroups, M406 and L141.1 which have their own sections.

Age of L30

No reliable information can be reported on the age of L30.  It is probably
somewhere in the range of 15,000 to 30,000 years but no one knows for 
sure.  

Rootsi et al. in their 2012 study calculated the coalescence time for L30 (which
they call M485) men as 12,700 yrs.  But this is little more than the time 
calculated for subgroups and thus may exclude men from older branches off of
L30.   For individual countries, the time ranged from 4,000 yrs among the
Druze of the Levant to 13,000 yrs in the Caucasus area.  This type calculation
is based on marker sample mutations, and counting the number of SNP
mutations in full sequencing is expected to be more reliable.

Geographical distribution of L30

With only one man reliably determined to fall within L30 but negative for
its subgroups, nothing can be reported about men in that situation.

Considering also L30's subgroups, in the Old World they are spread all
over Europe, northern Africa, western and southern Asia as well as parts
of western China.  But it is best to look at individual subgroups because
the migrations likely took place out of the Near East after the subgroups
were formed.

Origins of L30

Nothing can be said of the origins of L30, and it possible that the L30 
ancestors were just living in a small family group.  The period before L30
subgroups developed would have been a period of hunter gatherers who
kept no records.  

Maps of L30 Men

No specific L30 maps have been developed, and with only one man currently
in the group here, his location on the project map is rather meaningless.

Rootsi and others provided a coalescent age for L30:

Special Testing

The following L30+ men neg for subgroups  have the following results
for newer, poorly defined SNP mutations:  
                                                    + means positive, - means negative               

L190+ Bailey

         more info about these SNPs can be found at:
                   type L1325, for example, in the Landmark box.  After searching, look
                               for the small L1325 in the colored area and click on it.
