What a difference a year makes

What a difference a year makes.

Less than a year ago, the Italy DNA Project had 100 members. Over the past week, we have surpassed the 300 member mark. As I've done when we passed milestones in the past I wanted to take a minute to update folks on the current Y-DNA and mtDNA haplogroup breakdowns.

Here's the current version of the Y-DNA assignments, based on 207 Y-DNA members:

Haplogroup	Calculated Frequency of Haplogroups in Italy DNA Project
E3b1a	11.6%
E3b1b	1.4%
E3b1c	0.5%
G2	8.7%
I1a	2.9%
I1b*	1.0%
I1b1	1.4%
I1b2	2.9%
J1	4.3%
J2a	15.9%
J2b	1.9%
K2	3.9%
L	1.0%
Q	1.0%
R1a	2.9%
R1b1b	1.0%
R1b1c	34.3%
R1b1c6	0.5%
R1b1c9	1.0%
R1b1c10	1.4%
R2	0.5%

You can see that the classification scheme I used has changed a little since the last update, to favor more precise classification. In many cases, the precise classification scheme has depended on individual analysis and some estimation but I think the overall presenation is very accurate. One case where more testing is probably necessary is in the case of R1b1c. The levels of R1b1c9 and R1b1c10 are probably too low, since few members have tested the crucial S-series SNPs offered by Ethnoancestry.
