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 ...

Stochastic Processes in Population Genetics, with Special Reference to Distribution of Gene Frequencies and Probability of Gene Fixation

, 1970
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.

From Genomes to Populations: A Meta-analysis and Review of Fern Population Genetics

INTERNATIONAL JOURNAL PLANT SCIENCES, 2021
Premise of research. Numbering around 10,000 species, ferns are the second-largest group of vascular plants. Relatively little work, however, has focused on the population genetic processes driving fern evolution.

Analysis of the Fixation of Discrete Genetic Structures by Means of an Integral Model of Evolution in a Mendelian One-Locus Population of Diploid Organisms [PDF]

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

Role of genetics in eleven of the most common autoimmune diseases in the post genome-wide association studies era.

European Review for Medical and Pharmacological Sciences, 2023
Autoimmune diseases (ADs) are common conditions in which an individual's immune system reacts against its healthy cells. This condition is a common cause of morbidity and mortality, with an estimated prevalence ranging from 5 per 100,000 to more than 500

Fixation of alleles and depleted levels of genetic variation within populations of the endangered lithophytic orchid Amitostigma gracile (Orchidaceae) in South Korea: implications for conservation [PDF]

Plant Systematics and Evolution, 2008
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.

Fixation indices and genetic diversity in hermaphroditic and gynodioecious populations of Japanese Chionographis (Liliaceae) [PDF]

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 ...

Population genetics of American black bears in Georgia, USA

Ursus, 2019
: There are 3 American black bear (Ursus americanus) populations in the state of Georgia, USA. We used multi-locus microsatellite genotypes derived from bear hair and tissue samples collected across these populations to assess levels of genetic diversity
