Frequency correspondence analysis.
The potential reproductive capacity of an individual or population (e.g., the number of eggs or young produced by an individual per unit time).
The ability to conceive and have offspring. Sometimes used for fecundity.
See WrightFisher model.
The ability of an individual, or genotype to survive and produce viable offspring. Quantified as the number of offspring contributed to the next generation, or as proportion of the individual’s genes in all the genes contributed to the next generation.
Following an episode of inbreeding depression, successive generations of breeding may result in a rebound in fitness due to the selective decrease in frequency of deleterious alleles (purging). If inbreeding depression is due to deleterious recessive alleles (with negative fitness effects in a homozygous state) then successive generations of inbreeding may result in a rebound in fitness due to the selective decrease in frequency of deleterious alleles.
The proportional increase of homozygosity through population subdivision. FST is sometimes referred to as the fixation index.
fluctuating asymmetry (FA)
Asymmetry in which deviations from symmetry are randomly distributed about a mean of zero. FA provides a simple measure of developmental precision or stability.
The use of scientific methods and techniques, such as genetic fingerprinting, to solve crimes.
A loss of genetic variation in a population that was established by a small number of individuals that carry only a fraction of the original genetic diversity from a larger population. A special case of genetic drift.
Natural selection in which fitness varies as a function of the frequency of a phenotype.
