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 ...

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 ...
