Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing ...

Basic concepts in population genetics, including nucleotide diversity, random genetic drift, effective population size, coalescent theory, time to common ancestor, site frequency spectrum, linkage ...

Today a bitter dispute about the nature of biology is underway. A simple bag of beans may be what tips the balance ...

The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...

Genetics is the branch of science concerned with genes, heredity, and variation in living organisms. It seeks to understand the process of trait inheritance from parents to offspring, including ...

Scientists have long debated how modern humans evolved. For decades, most researchers agreed that Homo sapiens came from one ...

Some of the genes from Population B, "particularly those related to brain function and neural processing, may have played a crucial role in human evolution," study co-author Trevor Cousins, a ...

including the genetic risk of adverse pregnancy outcomes, hypertension, cardiovascular disease, cancers, and susceptibility to infection. An experienced population geneticist, he studies how genes, ...

The Finnish population is one of the most genetically studied in the world. A relatively small number of founder individuals and strong genetic isolation over centuries have shaped the unique genetic ...
