Jonathan Karl Pritchard is an English-born professor of genetics at Stanford University, best known for his development of the STRUCTURE algorithm for studying population structure and his work on human genetic variation and evolution. [3] His research interests lie in the study of human evolution, in particular in understanding the association between genetic variation among human individuals and human traits.

Education

Pritchard's family moved to the US when he was a teenager. He studied biology and mathematics at Pennsylvania State University, and then went on to graduate studies in biology at Stanford University under the supervision of Marc Feldman, finishing in 1998. [10]

Career

Pritchard conducted postdoctoral research with Peter Donnelly at the University of Oxford. It was there that he developed STRUCTURE, a widely used computer program for determining population structure and estimating individual admixture. [5] In 2001, he moved to the University of Chicago. He was promoted from Assistant Professor to Full Professor in 2006. He stayed there until moving to Stanford in 2013. [3] He was awarded a Howard Hughes Medical Institute (HHMI) investigator position in 2008. [10]

Awards and honours

Pritchard was a recipient of the 2013 Edward Novitski Prize from the Genetics Society of America and the 2002 Mitchell Prize from the International Society for Bayesian Analysis.

Personal life

Pritchard ran track and cross country for Pennsylvania State University from 1989 to 1994. In part because of his running experience, he appeared in the 1998 movie Without Limits portraying David Bedford, an English distance runner who participated in the 1972 Munich Olympics. As a result of his appearance in Without Limits and his publication of ″Population Growth of Human Y Chromosomes: A study of Y Chromosome Microsatellites″ with Marcus Feldman, [11] he has an Erdős–Bacon number of 6.

<span class="mw-page-title-main">Heredity</span> Passing of traits to offspring from the species parents or ancestor

Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics.

A microsatellite is a tract of repetitive DNA in which certain DNA motifs are repeated, typically 5–50 times. Microsatellites occur at thousands of locations within an organism's genome. They have a higher mutation rate than other areas of DNA leading to high genetic diversity. Microsatellites are often referred to as short tandem repeats (STRs) by forensic geneticists and in genetic genealogy, or as simple sequence repeats (SSRs) by plant geneticists.

Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.

Noah Aubrey Rosenberg is a geneticist working in evolutionary biology, human genetics, and population genetics, now Professor at Stanford University. His research is concerned with quantifiable changes in the human genome over time, and he is famous for his studies of human genetic clustering. He is the editor-in-chief of Theoretical Population Biology.

Human genetic variation is the genetic differences in and among populations. There may be multiple variants of any given gene in the human population (alleles), a situation called polymorphism.

Haplogroup T-M184, also known as Haplogroup T, is a human Y-chromosome DNA haplogroup. The unique-event polymorphism that defines this clade is the single-nucleotide polymorphism known as M184.

The various ethnolinguistic groups found in the Caucasus, Central Asia, Europe, the Middle East, North Africa and/or South Asia demonstrate differing rates of particular Y-DNA haplogroups.

Population genomics is the large-scale comparison of DNA sequences of populations. Population genomics is a neologism that is associated with population genetics. Population genomics studies genome-wide effects to improve our understanding of microevolution so that we may learn the phylogenetic history and demography of a population.

Population structure is the presence of a systematic difference in allele frequencies between subpopulations. In a randomly mating population, allele frequencies are expected to be roughly similar between groups. However, mating tends to be non-random to some degree, causing structure to arise. For example, a barrier like a river can separate two groups of the same species and make it difficult for potential mates to cross; if a mutation occurs, over many generations it can spread and become common in one subpopulation while being completely absent in the other.

Listed here are notable ethnic groups and populations from Western Asia, Egypt and South Caucasus by human Y-chromosome DNA haplogroups based on relevant studies. The samples are taken from individuals identified with the ethnic and linguistic designations in the first two columns, the third column gives the sample size studied, and the other columns give the percentage of the particular haplogroup. Some old studies conducted in the early 2000s regarded several haplogroups as one haplogroup, e.g. I, G and sometimes J were haplogroup 2, so conversion sometimes may lead to unsubstantial frequencies below.

In genetics, haplotype estimation refers to the process of statistical estimation of haplotypes from genotype data. The most common situation arises when genotypes are collected at a set of polymorphic sites from a group of individuals. For example in human genetics, genome-wide association studies collect genotypes in thousands of individuals at between 200,000-5,000,000 SNPs using microarrays. Haplotype estimation methods are used in the analysis of these datasets and allow genotype imputation of alleles from reference databases such as the HapMap Project and the 1000 Genomes Project.

Mega2 allows the applied statistical geneticist to convert one's data from several input formats to a large number output formats suitable for analysis by commonly used software packages. In a typical human genetics study, the analyst often needs to use a variety of different software programs to analyze the data, and these programs usually require that the data be formatted to their precise input specifications. Conversion of one's data into these multiple different formats can be tedious, time-consuming, and error-prone. Mega2, by providing validated conversion pipelines, can accelerate the analyses while reducing errors.
