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 ...

Assessment of the genetic diversity of Plasmodium falciparum in 110 Colombian isolates revealed that nearly all the parasites in the 97 isolates collected in endemic regions west of the Andes shared the same Pfmsp1 block 2 MAD20-type allelic variant, despite showing high diversity for other genetical markers.

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.

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.

Russian Journal of Genetics, 2004
An integral model of the evolution of a Mendelian one-locus population of diploid organisms with continual allele diversity developing under density-limiting conditions or without density limitation has been proposed and analyzed. The model was used to study the mechanism of the appearance of discrete genetic structures, i.e., the fixation of a limited

To date, empirical studies on levels of genetic diversity in highly isolated populations of lithophytic orchids are few. We investigated levels of allozyme diversity and spatial distribution of genotypes in small, isolated populations of the endangered, self-compatible lithophyte Amitostigma gracile from southern Korea.

Heredity, 1992
In Japanese Chionographis, populations are either hermaphroditic or gynodioecious, and diploid or tetraploid. The average level of inbreeding was compared among these populations by estimating Wright's fixation index. The estimates were significant in all gynodioecious populations irrespective of ploidy level, and hermaphrodites in gynodioecious ...

The fundamental quantity which is used in population genetics to describe the genetic composition of a Mendelian population (i.e. reproductive community) is the gene frequency, or the proportion of a given gene in the population. Thus, a population is characterized by a set of gene frequencies.
