Allelic diversity and its implications for the rate of adaptation.
Genetic variation is usually estimated empirically from statistics based on population gene frequencies, but alternative statistics based on allelic diversity (number of allelic types) can provide complementary information. There is a lack of knowledge, however, on the evolutionary implications attached to allelic-diversity measures, particularly in structured populations. In this article we si...
متن کاملLong-term Response: Finite Populations
Genetic drift is of considerable importance in most artificial selection experiments, which tend to have very small effective population sizes. We have previously considered the short-term implications of drift in generating variance around the expected response (Chapter 6), which occurs even in the absence of major changes in allele frequencies. This chapter examines the implications for long-...
متن کاملEvolutionary and convergence stability for continuous phenotypes in finite populations derived from two-allele models.
The evolution of a quantitative phenotype is often envisioned as a trait substitution sequence where mutant alleles repeatedly replace resident ones. In infinite populations, the invasion fitness of a mutant in this two-allele representation of the evolutionary process is used to characterize features about long-term phenotypic evolution, such as singular points, convergence stability (establis...
متن کاملGenetic variation in a heterogeneous environment. II. Temporal heterogeneity and directional selection.
The maintenance of genetic variation is investigated in a finite population where selection at an autosomal locus with two alleles varies temporally between two environments and the heterozygote has an intermediate fitness value. When there is additive gene action and equal selection in both environments, the autocorrelation between subsequent environments must be negative for more maintenance ...
متن کاملComparision of Direct and Indirect Response to Selection for Breast Weight in Japanese Quail
This study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk BW)) and four-week breast weight (4 week breast weight (wk BRW)) and to determine the genetic contribution of reminder founders to the last generation. A total number of 351 birds were equally allocated to three lines, including two selected lines (S1 and S2 for BW...
