Often called gene frequency. A measure of how common an allele is in a population; the proportion of all alleles at one genelocus that are of one specific type in a population. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ... Full article >>>
Genetic drift describes changes in gene frequency that cannot be ascribed to selective pressures, but are due instead to events that are unrelated to inherited traits. Full article >>>
Studies in Sardinia and Papua New Guinea have found that the gene frequency of β-thalassaemias is related to the level of endemicity in a given population. Full article >>>
founder effect Changes in gene frequency that occur when a few individuals from a parental populationcolonize new habitats; the change is a result of founding individuals not having a representative sample of the parental population's genes. Full article >>>
stimates phylogenies from gene frequency data by maximum likelihood under a model in which all divergence is due to genetic drift in the absence of new mutations ( ... Full article >>>
This outcome is similar to the operation of genetic drift in neutral alleles of nuclear genes: in due course a given allele reaches a gene frequency of 100% or disappears entirely [Link to discussion]. Full article >>>
