Trading genes along the silk road: mtDNA sequences and the origin of central Asian populations.
TLDR
It seems unlikely that altitude has exerted a major selective pressure on mitochondrial genes in central Asian populations, because lowland and highland Kirghiz mtDNA sequences are very similar, and the analysis of molecular variance has revealed that the fraction of mitochondrial genetic variance due to altitude is not significantly different from zero.
Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.
TLDR
These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift.
High-resolution analysis of human Y-chromosome variation shows a sharp discontinuity and limited gene flow between northwestern Africa and the Iberian Peninsula.
TLDR
The most striking results are that contemporary NW African and Iberian populations were found to have originated from distinctly different patrilineages and that the Strait of Gibraltar seems to have acted as a strong (although not complete) barrier to gene flow.
Genetic and demographic implications of the Bantu expansion: insights from human paternal lineages.
TLDR
A recent origin for most paternal lineages in west Central African populations most likely resulting from the expansion of Bantu-speaking farmers that erased the more ancient Y-chromosome diversity found in this area, and the intriguing presence of paternal lineage belonging to Eurasian haplogroup R1b1*, which might represent footprints of demographic expansions in central Africa not directly related to the BantU expansion.
Variation in short tandem repeats is deeply structured by genetic background on the human Y chromosome.
TLDR
Genetic variability appears to be much more structured by lineage than by population, and the deep structure of the genetic variation in old genealogical units (haplogroups) challenges a population-based perspective in the comprehension of human genome diversity.
Mitochondrial DNA variation and the origin of the Europeans
TLDR
Estimated expansion times indicate a Paleolithic event with important differences among populations according to their geographical position and thus a slower tempo than previously believed and the replacement of Neanderthals by anatomically modern humans may have been a slower and more complex process than cultural change suggests.
Paternal and maternal lineages in the Balkans show a homogeneous landscape over linguistic barriers, except for the isolated Aromuns
TLDR
This work has sought to find any evidence of genetic stratification related to those cultural layers by typing both mtDNA and Y chromosomes, in Albanians, Romanians, Macedonians, Greeks, and five Aromun populations.
Human mitochondrial DNA sequence variation in the Moroccan population of the Souss area
TLDR
TheSub-Saharan admixture in the Souss Valley matched the south-north cline of sub-Saharan influence in North Africa, also evident in the genetic distances of North African populations to Europeans and sub-Sahara Africans.
