Genetic drift is a random process that can lead to the fixation of alleles, but at the cost of losing alleles, especially those with low frequencies, and to increased homozygosity in the population. This process is described for an idealised population and its effect illustrated on different popu...
Genetic driftSimulationsNeutral evolution is a fundamental concept in evolutionary biology but teaching this and other non-adaptive concepts is especially challenging. Here we present Genie, a browser-based educational tool that demonstrates population-genetic concepts such as genetic drift, population ...
As such, clustering is interpreted as identity, due to common ancestry and its absence as genetic drift. Populations nested between other populations are admixed or isolates, and those at the corners of the PC scatter plot are unmixed, pure, or races. Although a newly coined term, the roots...
Simulation of genetic drift in closed population under different initial gene frequencies. Computer simulation was used to determine the random genetic drifts of a biallelic gene locus in closed populations under different initial gene frequencie... LU Shao-Xiong,HM Mao,LU Li-Gang,... - 《Jiangsu...
In the context of large effective population size, the genetic drift will be limited and only a small amount of migration is required to maintain genetic homogeneity. Considering the isolated aggregations of P. nobilis located in lagoons, the potential for a high self-recruitment rate remains ...
Establishing a base population for a breeding program in aquaculture, from multiple subpopulations, differentiated by genetic drift: II. Sensitivity to ass... The simulation study examined the effect in optimal contribution selection of specifying an additive genetic relationship matrix (A-matrix) deviati...
Cavalli-Sforza and Edwards distance is similar to Modified Rogers distance, however, it assumes a selective drift model where samples are subject to a low mutation rate and rapid changes in selective pressure [29]. For this reason, Modified Rogers distance may be a more suitable measure than Ca...
[1–7]). Marine pelagic fishes exhibit great dispersal capability that enhances gene flow, as well as large effective population sizes that impose limitations to genetic drift (e.g. [8–11]). The combination of both life-history traits acts as major homogenizing force, which hampers genetic ...
Patterns of variation and covariation within populations can influence how characters respond to natural selection and random genetic drift and so constrai... Miriam Leah Zelditch and A. Christopher Carmichael - 《Evolution》 被引量: 408发表: 1989年 Morphometrics and the role of the phenotype in ...
Here we investigate the effect of a simulation-based module about the conservation of black-footed ferrets, a module designed with pedagogical approaches that have been demonstrated to be effective, for teaching genetic drift. We compared performance on the Genetic Drift Inventory (GeDI) of students...
