▪ Abstract It is not generally realized that genetics has finally solved the age-old problem of
the reason for the existence (ie the function) of sexuality and sex, and that only geneticists …

Photoreactivation, one of the first DNA repair pathways to evolve, is the direct reversal of
premutagenic lesions caused by ultraviolet (UV) irradiation, catalyzed by photolyases in a …

Natural selection acts in three ways on heritable variation for mutation rates. A modifier
allele that increases the mutation rate is (i) disfavored due to association with deleterious …

Modifier gene models are used to explore the evolution of features of organisms, such as the
genetic system, that are not directly involved in the determination of fitness. Recent work has …

Conversion between duplicated genes limits their independent evolution. Models in which
conversion frequencies decrease as genes diverge are examined to determine conditions …

Modifier-gene models for the evolution of genetic information transmission between
generations of organisms exhibit the reduction principle: Selection favors reduction in the …

A general approach is developed to estimate secondary selection at a modifier locus that
influences some feature of a population under mutation-selection balance. The approach is …

A new method is presented for analysing the dynamics of a classical model where
infinitesimally rare alleles segregate at an infinite number of unlinked loci, and where the …

For any 2-locus viability system with a neutral recombination-modifying locus, it was shown
by Feldman et al.[Proceedings of the National Academy of the United States of America 77 …

In a recent paper, JM McNamara and SR Dall identified novel relationships between (1) the
abundance of a species in different environments,(2) the temporal properties of …
