Abstract

Variation in learning abilities within populations suggests that complex learning may not necessarily be more adaptive than simple learning. Yet, the high cost of complex learning cannot fully explain this variation without some understanding of why complex learning is too costly for some...

Abstract

At a small number of loci in eutherian mammals, only one of the two copies of a gene is expressed; the other is silenced. Such loci are said to be "imprinted," with some having the maternally inherited allele inactivated and others showing paternal inactivation. Several hypotheses have been...

Abstract

Modifier theory was used to compare the evolution of recombination under mutation-selection and migration-selection balance models. Recombination between loosely linked loci subject to weak multilocus selection was controlled by the genotype at a selectively neutral modifier locus. It was shown...

Abstract

Nine diallelic models of genetic conflict are presented in which one allele is imprintable and the other is not to examine how genomic imprinting may have evolved. Imprinting is presumed to be either maternal (the maternally derived gene is inactivated) or paternal. Females are assumed to be either ...

Abstract

The conditions allowing increased recombination to evolve in the presence of recurrent deleterious mutation were examined using a 3-locus model of Feldman et al. [Proceedings of the National Academy of Sciences of the United States of America (1980) 77, 4838-4841]. It was shown that alleles that...

Abstract

Optimality arguments and modifier theory are reviewed as paradigms for the study of the evolution of recombination. Optimality criteria (such as maximization of mean fitness) may agree with results from models developed in terms of the evolution of recombination at modifier loci. Modifier models...

Abstract

A genetic model for the dynamics of a quantitative trait was analysed in terms of gene frequency, linkage disequilibrium and environmental effects on the trait. In a randomly mating population, at each generation progeny move to niches where they are subject to weak Gaussian selection on the trait, ...

Abstract

Allozyme data for pink salmon populations were used to examine the theoretical models available for estimating the effects of genetic drift, migration and/or selection on observed gene differentiation in Pacific salmon populations. The models included (1) mutation and genetic drift, (2) mutation...

Abstract

A 2-locus genetic model was studied in which one locus controls the tendency of individuals to act altruistically toward siblings and the other locus controls the mating habits of ♀♀. It is demonstrated that genetic variation at the altruism locus is often sufficient to induce an increase in the...
