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.
