allélfrekvenciákkal
Allele frequency, or allélfrekvencia in Hungarian, refers to the relative proportion of a specific allele within a population's gene pool. It is a fundamental concept in population genetics and evolutionary biology. For a given gene, there may be multiple alleles, which are different versions of that gene. The allele frequency is expressed as a decimal or percentage, representing how often a particular allele appears compared to all other alleles for that gene in the population. For example, if a gene has two alleles, A and a, and the frequency of allele A is 0.7 and the frequency of allele a is 0.3, it means that in that population, 70% of the gene copies are A and 30% are a. Allele frequencies can change over time due to evolutionary forces such as mutation, gene flow, genetic drift, and natural selection. Monitoring these frequencies allows scientists to understand population dynamics, track evolutionary changes, and assess the genetic diversity within species. Changes in allele frequency are the basis of evolution at the population level.
