Genetics Selection Evolution (known as GSE, and abbreviated with Genet. Sel. Sel. Evol.) is a bimonthly online-only peer-reviewed scientific journal covers original research on all aspects of genetics and selection in domestic animal species and other species providing results of immediate interest for farm animals' genetics.
Selection coefficient, usually denoted by the letter s, is a measure used in population genetics to quantify the relative fitness of a genotype compared to other genotypes. . Selection coefficients are central to the quantitative description of evolution, since fitness differences determine the change in genotype frequencies attributable to selecti
Genome Biology and Evolution is a monthly peer-reviewed open access scientific journal published by Oxford University Press on behalf of the Society for Molecular Biology and Evolution. It covers research on the interface between evolutionary biology and genomics. [1] According to the Journal Citation Reports, the journal has a 2022 impact ...
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
The effective population size (N e) is the size of an idealised population that would experience the same rate of genetic drift as the real population. The effective population size is normally smaller than the census population size N, partly because chance events prevent some individuals from breeding, and partly due to background selection and genetic hitchhiking.
Haldane's sieve is particularly relevant in situations where the effects of natural selection are strong and the beneficial mutations have a significant impact on an organism's fitness. According to Haldane's sieve, when a new advantageous mutation arises in a population, it initially occurs as a single copy (a de novo mutation ), borne by an ...
In genetics, a selective sweep is the process through which a new beneficial mutation that increases its frequency and becomes fixed (i.e., reaches a frequency of 1) in the population leads to the reduction or elimination of genetic variation among nucleotide sequences that are near the mutation.
Bateman's paradigm thus views females as the limiting factor of parental investment, over which males will compete in order to copulate successfully. Although Bateman's principle served as a cornerstone for the study of sexual selection for many decades, it has recently been subject to criticism. Attempts to reproduce Bateman's experiments in ...
