TLDR
Evidence indicates that inbreeding plant species show more intense geographic and microgeographic differentiation, and more intense multilocus associations than outbreeders, and a closer integration of the joint microevolution of mating systems, and of genetic variation is required.About:

Journal ArticleDOI
Inbreeding depression and its evolutionary consequences
TL;DR: The evidence that the evolution of breeding systems of animals and plants has been significantly influenced by the occurrence of inbreeding depression is reviewed, and the contemporary genetic theory of inmarriage depression and heterosis and the experimental data concerning the strength of in breeding depression are considered.

Effects of life history traits on genetic diversity in plant species
J. L. Hamrick,M. J. W. Godt +1 more
TL;DR: An analysis of twelve plant families indicated that species within families with predominately outcrossing, woody species had more genetic diversity and less interpopulation differentiation than species withinfamilies with predominate herbaceous species.
Journal ArticleDOI
The evolution of self-fertilization and inbreeding depression in plants. i. genetic models
TL;DR: Genetic models are constructed which allow inbreeding depression to change with the mean selfing rate in a population by incorporating both mutation to recessive and partially dominant lethal and sublethal alleles at many loci and mutation in quantitative characters under stabilizing selection.
Journal ArticleDOI
Factors influencing levels of genetic diversity in woody plant species
TL;DR: Woody species with large geographic ranges, outcrossing breeding systems, and wind or animal-ingested seed dispersal have more genetic diversity within species and populations but less variation among populations than woodyspecies with other combinations of traits.
Journal ArticleDOI
Genetic distance between populations
TL;DR: It is shown that the result known as Wahlund's principle can be expressed as a simple function of genic distances among the subpopulations, and if used with caution it can be employed to recognize mixtures of seed lots.

Analysis of Gene Diversity in Subdivided Populations
TL;DR: 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.

The interpretation of population structure by F-statistics with special regard to systems of mating
TL;DR: It was found that there is no equilibrium in either case short of complete fixation locally, in spite of the linear increase in number of different ancestors with increasing number of ancestral generations, in contrast to systems (half first cousin or second cousin) in which this increase is more than linear and a steady state is rapidly attained with respect to heterozygosis.
