A criterion for stability-instability at fixation states involving an eigenvalue one with applications in population genetics

Theoretical Population Biology, 1982
Abstract An explicit general criterion for stability-instability at fixation states is provided when the leading eigenvalue of the gradient matrix is one. Several applications in population genetics are presented including cases of familial selection of dominant and recessive genes, models of preferential mating, incompatibility systems, and effects ...

POPULATION GENETICS, PLEIOTROPY, AND THE PREFERENTIAL FIXATION OF MUTATIONS DURING ADAPTIVE EVOLUTION

Evolution, 2010
Ongoing debate centers on whether certain types of mutations are fixed preferentially during adaptive evolution. Although there has been much discussion, no quantitative framework currently exists to test for these biases. Here, we describe a method for distinguishing between the two processes that likely account for biased rates of substitution ...

The genetic diversity and applicability assessment of autosomal STRs among Chinese populations by a novel Fixation Index and Nei’s index

Legal Medicine, 2018
The population-specific FST in STR loci of Chinese populations has not been focused on. Here, we genotyped 19 STRs in 530 unrelated healthy individuals of Xuzhou Han population, and collected data of 30,308 samples from 32 Hans and 50 minorities nationwide.

Population Genetic Structure and the Fixation of Chromosomal Rearrangements in Sceloporus grammicus (Sauria, Iguanidae): A Computer Simulation Study

Copeia, 1988
This paper reports on a series of computer simulations designed to examine some population genetic correlates associated with the stochastic fixation of novel chromosomal rearrangements appearing in small isolated populations as specified by the cascading speciation model.
