A graphical representation of the typical human karyotype The human mitochondrial DNA. Human genetic variation is the genetic differences in and among populations.There may be multiple variants of any given gene in the human population (), a situation called polymorphism.
Millions of people use genetic testing companies like 23andMe to learn more about their ancestry and health. But a new data breach is highlighting the risks of having your ancestry information ...
This is a list of haplogroups of historic people. Haplogroups can be determined from the remains of historical figures, or derived from genealogical DNA tests of people who trace their direct maternal or paternal ancestry to a noted historical figure. Some contemporary notable figures have made their test results public in the course of news ...
A wide range of methods have been developed to assess the structure of human populations with the use of genetic data. Early studies of within and between-group genetic variation used physical phenotypes and blood groups, with modern genetic studies using genetic markers such as Alu sequences, short tandem repeat polymorphisms, and single nucleotide polymorphisms (SNPs), among others.

A 2005 study found that chimpanzees -- our closest living evolutionary relatives -- are 96 percent genetically similar to humans. BI GRAPHICS_percentage of DNA humans share with other things ...
Next, each linker part is attached to its respective DNA part by incubating with T4 DNA ligase. Each DNA part will have a suffix and prefix linker part from two different linkers to direct the order of assembly. For example, the first part in the sequence will have L1P and L2S, while the second part will have L2P and L3S attached.
Virginia Beach police used forged documents that linked people's DNA to a crime to get them to confess or cooperate with investigators, Virginia's outgoing attorney general announced Wednesday.
A DNA segment is identical by state (IBS) in two or more individuals if they have identical nucleotide sequences in this segment. An IBS segment is identical by descent (IBD) in two or more individuals if they have inherited it from a common ancestor without recombination, that is, the segment has the same ancestral origin in these individuals.
