Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.

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. Expand
Prehistoric and historic traces in the mtDNA of Mozambique: insights into the Bantu expansions and the slave trade.

The forced displacement of Mozambicans as part of the slave trade generated a differential input of eastern African sequences into the mtDNA pools of the Americas and of Europe, as testified to by the greater number of sequence matches between Mozambique and the Americas, compared to those between Moz Ambique and Europe.

High-resolution mtDNA evidence for the late-glacial resettlement of Europe from an Iberian refugium.
A large fraction of the maternal ancestry of modern Europeans traces back to the expansion of hunter-gatherer populations at the end of the last Ice Age, as shown by the patterns of frequency and diversity of haplogroup H. Expand
The genetic legacy of western Bantu migrations
A dramatic displacement of male and female Khoisan-speaking groups in the southwest is revealed and the data indicate that the western stream of the Bantu expansion was a more gradual process than the eastern counterpart, which likely involved multiple short dispersals. Expand
Diversity of mtDNA lineages in Portugal: not a genetic edge of European variation
It is hypothesised that the recent Black African slave trade could have been the mediator of most of the L sequence inputs, while the population movement associated with the Muslim rule of Iberia has predominantly introduced U6 lineages. Expand
mtDNA phylogeny and evolution of laboratory mouse strains.
It is shown here that all common inbred strains descend from the same Mus musculus domesticus female wild ancestor, and it is suggested that they present a different mitochondrial evolutionary process than their wild relatives with a faster accumulation of replacement substitutions. Expand
New Microsatellite Multiplex PCR for Candida albicans Strain Typing Reveals Microevolutionary Changes
- P. Sampaio, L. Gusmão, +5 authors C. Pais

- Journal of Clinical Microbiology
- 1 August 2005
Analysis of the microevolutionary changes between isolates from recurrent infections indicated that the genotype alterations observed could be the result of events that lead to the loss of heterozygosity (LOH), and this could be related to exposure to fluconazole, since such strains were exposed to this antifungal during treatment.

Counting the Founders: The Matrilineal Genetic Ancestry of the Jewish Diaspora
The numerically major portion of the non-Ashkenazi Jews, currently estimated at 5 million people and comprised of the Moroccan, Iraqi, Iranian and Iberian Exile Jewish communities showed no evidence for a narrow founder effect, which did however characterize the smaller and more remote Belmonte, Indian and the two Caucasus communities.

Interleukin 1B and interleukin 1RN polymorphisms are associated with increased risk of gastric carcinoma.
- J. Machado, P. Pharoah, +8 authors M. Sobrinho-Simões
- Biology, Medicine
- 1 October 2001
A significant association between the IL-1 polymorphisms and increased risk for tumor development in patients with intestinal-type gastric carcinoma is found and evidence pointing to the existence of a synergistic interaction between theIL-1B and IL- 1RN polymorphisms is found. Expand
Revealing the History of Sheep Domestication Using Retrovirus Integrations
By using endogenous retroviruses as genetic markers, it is found that sheep differentiated on the basis of their “retrotype” and morphological traits dispersed across Eurasia and Africa via separate migratory episodes. Expand
