Analysis of gene diversity in subdivided populations.
A method is presented by which the gene diversity (heterozygosity) of a subdivided population can be analyzed into its components, i.e., the gene diversities within and between subpopulations. This method is applicable to any population without regard to the number of alleles per locus, the pattern of evolutionary forces such as mutation, selection, and migration, and the reproductive method of...
متن کاملEnvironmental variation, fluctuating selection and genetic drift in subdivided populations.
Although there have many studies of the population genetical consequences of environmental variation, little is known about the combined effects of genetic drift and fluctuating selection in structured populations. Here we use diffusion theory to investigate the effects of temporally and spatially varying selection on a population of haploid individuals subdivided into a large number of demes. ...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولThe Distribution of Gene Frequencies in Populations.
The effects of the various evolutionary factors-mutation, cross breeding,. selection and inbreeding-can be reduced to common terms by considering the rates of change which they tend to bring about in the relative frequencies of alleles.' In the absence of such factors, there is constancy of gene frequencies from the symmetry of the Mendelian mechanism. The frequency (q) of a given gene changes ...
متن کاملDispersal polymorphisms in subdivided populations.
Price's method for analyzing natural selection in subdivided populations is applied to the problem of dispersal polymorphism strategies in a stable habitat. The results agree with the more traditional Mendelian models for this same problem that have recently been published. Further, by using Price's method, the results obtained are simpler and more general, and the causal evolutionary mechanism...
