International Society of Genetic Genealogy (ISOGG) The first society founded to promote the use of DNA testing in genealogy! With links to a wealth of genetic genealogy tools and information.
Contexo.Info A website about the foundations of molecular genetics and biology. An excellent site for those who are looking for more details on DNA.
Time to Most Recent Common Ancestry Calculator by Bruce Walsh The goal is to use genetic markers (here on the Y chromosome) to estimate the TMRCA, the Time to the Most Recent Common Ancestor (MRCA), which is how many generations the two Y chromosomes are from a common ancestor. This site explains the various models used to determine TMRCA.
The National Human Genome Research Institute The National Human Genome Research Institute (NHGRI) created the Talking Glossary of Genetic Terms to help people without scientific backgrounds understand the terms and concepts used in genetic research.
Human Genome Project Information The Human Genome Project (HGP) is an international effort to discover all the approximately 30,000 to 35,000 human genes (the human genome), make them accessible for further biological study, and determine the complete sequence of the 3 billion DNA subunits (bases).
Why Y? The Y Chromosome in the Study of Human Evolution, Migration and Prehistory Neil Bradman and Mark Thomas of The Centre for Genetic Anthropology at University College London reveal the power of modern genetic analysis for exploring the role of fathers in human history.
Short Tandem Repeat DNA Internet DataBase While the use of STRs for genetic mapping and identity testing has become widespread among DNA typing laboratories, there is no single place where information may be found regarding STR systems. This web site is an attempt to bring together the abundant literature on the subject in a cohesive fashion to make future work in this field easier. Facts and sequence information on each STR system, population data, commonly used multiplex STR systems, PCR primers and conditions, and a review of various technologies for analysis of STR alleles have been included in this database.
GENEALOGY-DNA-L This mailing list is for anyone with DNA (i.e., anyone!) who would like to discuss methods and share results of DNA testing as applied to genealogical research.
Genetic Genealogy and Telephone Tag A simplified explanation of how Y-DNA mutates.
