Subject: [DNA] Norwegian regional variance and modals part 1

Hi list,

I have made straightforward variance and modals analysis of the supplementary data from Dupuy 2005 using the VAR() and MODE() function in MS Excel and wish for a second view of these findings. There may be errors I am not able to see now, I am assuming that loci with 0 variance should be excluded from the averaging as this made my N3 variance calculation somewhat in accordance with the N3 the latest paper of Rootsi 2006 where the national N3 variance was calculated to 0.27 (I got 0.29). If anyone know their formula let me know, I didnt manage in the endless chain of references.

These are the regional haplogroup frequencies, the hg notation is not exactly as in Dupuy but I use these because they probably are good aproximations and easier to remember.

Region I1a R1b R1a Oslo 40,4 35,8 19,3 Bergen 33,3 35,5 28 South 42,2 44,7 13,2 West 30,2 43,2 24,3 Middle 39,7 27,1 31,5 North 34,7 26,8 27,1 East 41,4 26,4 26,8

Samples in each region to each hg studied, these cover most of the samples.

Region I1a R1b R1a Oslo 57 39 21 Bergen 30 33 26 South 33 34 10 West 91 130 73 Middle 126 86 100 North 131 101 102 East 204 130 132

The sample variations for each hg and each region

Region I1a R1b R1a Oslo 0,49 0,41 0,33 Bergen 0,35 0,44 0,39 South 0,54 0,37 0,31 West 0,40 0,35 0,36 Middle 0,42 0,59 0,28 North 0,30 0,66 0,41 East 0,41 0,62 0,30

Comment: R1b freq is lowest in east, north and middle, these are also the areas where R1b have their highest frequency especially in the north and the east. It may have to do with the sample size. I1a have lowest freq in west and north, and highest in the south, and highest variance in the south and lowest in the north. R1a have highest freq in the north and have its lowest variance in the middle and in the east.
