Noah A Rosenberg, Jonathan T L Kang
The magnitude of genetic diversity within human populations varies in a way that reflects the sequence of migrations by which people spread throughout the world. Beyond its use in human evolutionary genetics, worldwide variation in genetic diversity sometimes can interact with social processes to produce differences among populations in their relationship to modern societal problems. We review the consequences of genetic diversity differences in the settings of familial identification in forensic genetic testing, match probabilities in bone marrow transplantation, and representation in genome-wide association studies of disease...

This study presents an overview of online databases for mtDNA and Y chromosome polymorphisms in human populations. In order to provide readers with information which may help optimize their use, we focus on: (i) type, quantity and source of data contained; (ii) possibilities of downloading and uploading; (iii) availability of data filters and population genetics tools. We show that some of these databases offer a useful complement to the primary databases by giving access to additional data and making it possible to perform queries which exploit some specific metadata...

REVIEW
John Novembre, Eunjung Han
The past few years of research in human evolutionary genetics have provided novel insights and questions regarding how human adaptations to recent selective pressures have taken place. Here, we review the advances most relevant to understanding human evolution in response to pathogen-induced selective pressures. Key insights come from theoretical models of adaptive evolution, particularly those that consider spatially structured populations, and from empirical population genomic studies of adaptive evolution in humans...

The mitochondrial DNA hypervariable segment I (HVS-I) is widely used in studies of human evolutionary genetics, and therefore accurate estimates of mutation rates among nucleotide sites in this region are essential. We have developed a novel maximum-likelihood methodology for estimating site-specific mutation rates from partial phylogenetic information, such as haplogroup association. The resulting estimation problem is a generalized linear model, with a nonstandard link function. We develop inference and bias correction tools for our estimates and a hypothesis-testing approach for site independence...

In forensic casework, Y chromosome short tandem repeat markers (Y-STRs) are often used to identify a male donor DNA profile in the presence of excess quantities of female DNA, such as is found in many sexual assault investigations. Commercially available Y-STR multiplexes incorporating 12-17 loci are currently used in forensic casework (Promega's PowerPlex Y and Applied Biosystems' AmpFlSTR Yfiler). Despite the robustness of these commercial multiplex Y-STR systems and the ability to discriminate two male individuals in most cases, the coincidence match probabilities between unrelated males are modest compared with the standard set of autosomal STR markers...

Determining the evolutionary relationships between fossil hominid groups such as Neanderthals and modern humans has been a question of enduring interest in human evolutionary genetics. Here we present a new method for addressing whether archaic human groups contributed to the modern gene pool (called ancient admixture), using the patterns of variation in contemporary human populations. Our method improves on previous work by explicitly accounting for recent population history before performing the analyses...

After a short review on opinions about human evolutionary genetics and the prospects for understanding the biological variation present in our species, descriptions are made for studies performed in Brazil concerning: (a) C-band variability in chromosomes 1, 9, 16 and Y in Indian populations, with a Caucasoid sample used for comparison; (b) The paradox of the restricted number of HLA haplotypes observed in Indian groups, coupled with a finding of significantly less homozygotes than those expected assuming Hardy-Weinberg equilibrium; (c) The distribution of Gc and Tf isoelectric focusing subtypes in Indians and its anthropological significance; (d) Racial admixture quantitative estimations in samples from two Indian tribes and two cities...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
