Thesis of Oleg Balonovsky

is available here as pdf. Lots of interesting information, and a few striking maps. Hopefully, the fact that it's all in Russian won't be much of a problem in this day and age.
I will highlight a few pieces of information. First, a distribution of Y-chromosome haplogroups in Russian groups:

Notice:

• N1c-Tat is a general feature of the Russians, but N1b-P43 is only really found at any significant frequency in the northern groups.
• A strong contrast of E-M78 between central (present) and northern (absent) groups, consistent with a late introduction of this haplogroup in easternmost Europe.
• South-Central-North decreasing frequency of R1a; now, it's not clear how R1a came to be in Russians: some of it may be legacy of its initial entry into Europe from the east, other could be of historical import, and may have even arrived during the Slavic expansion from Central Europe. The pattern probably is the reverse of the high frequency of N1, indicating increasing importance of Finno-Ugric substratum in the north.
• Fairly interesting that of the two likely "Balkan" haplogroups E-M78 and I-P37, the former is modal in central region, the latter in southern one. The absence of both in "deep Asia" suggests a late introduction, as mentioned before, but when?

Also of interest a haplotype analysis within R1a1a-M198:

My most immediate observation is the set of mainly Indian highly divergent haplotypes on the left. There has been (well-deserved) excitement about recent Y-SNP progress within this haplogroup, but we should not neglect the occurrence of outliers/relics in our reconstruction of a haplogroup's history. I'd love to see those few Indian haplotypes SNP-tested using the currently available SNPs, or even used to develop new SNPs for this important Eurasian haplogroup.

mtDNA and Y chromosomes of Yakuts

mtDNA and Y chromosomes of Yakuts

In agreement with a recent autosomal DNA study on the Yakuts, this ethnic group is characterized by mainly Mongoloid mtDNA haplogroups (A, B, C, D, G, and F) as well as the Uralic-Mongoloid Y-haplogroup N3.

[MtDNA and Y-chromosome lineages in the Yakut population]
Puzyrev VP et al.

The structure of female (mtDNA) and male (Y-chromosome haplotypes) lineages in the Yakut population was examined. To determine mtDNA haplotypes, sequencing of hypervariable segment I and typing of haplotype-specific point substitutions in the other parts of the mtDNA molecule were performed. Y haplogroups were identified through typing of biallelic polymorphisms in the nonrecombining part of the chromosome. Haplotypes within haplogroups were analyzed with seven microsatellite loci. Mitochondrial gene pool of Yakuts is mainly represented by the lineages of eastern Eurasian origin (haplogroups A, B, C, D, G, and F). In Yakuts haplogroups C and D showing the total frequency of almost 80% and consisting of 12 and 10 different haplopypes, respectively, were the most frequent and diverse. The total part of the lineages of western Eurasian origin ("Caucasoid") was about 6% (4 haplotypes, haplogroups H, J, and U). Most of Y chromosomes in the Yakut population (87%) belonged to haplogroup N3 (HG16), delineated by the T-C substitution at the Tat locus. Chromosomes of haplogroup N3 displayed the presence of 19 microsatellite haplotypes, the most frequent of which encompassed 54% chromosomes of this haplogroup. Median network of haplogroup N3 in Yakuts demonstrated distinct "starlike phylogeny". Male lineages of Yakuts were shown to be closest to those of Eastern Evenks.
