▪ Abstract Phenotypic variation for quantitative traits results from the segregation of alleles at
multiple quantitative trait loci (QTL) with effects that are sensitive to the genetic, sexual, and …

▪ Abstract This review focuses on five key evolutionary issues pertaining to animal cognition,
defined as the neuronal processes concerned with the acquisition, retention, and use of …

The independent evolution of the sexes may often be constrained if male and female
homologous traits share a similar genetic architecture. Thus, cross-sex genetic covariance is …

Sexually antagonistic alleles are selected discordantly between the sexes. Experimental
evidence indicates that sexually antagonistic fitness variation is abundant in the genome of …

Most organisms rely on olfaction for survival and reproduction. The olfactory system of
Drosophila melanogaster is one of the best characterized chemosensory systems and …

Senescence, the decline in survivorship and fertility with increasing age, is a near-universal
property of organisms. Senescence and limited lifespan are thought to arise because weak …

Behaviours are exceptionally complex quantitative traits. Sensitivity to environmental
variation and genetic background, the presence of sexual dimorphism, and the widespread …

Understanding the relationship between genetic variation and phenotypic variation for
quantitative traits is necessary for predicting responses to natural and artificial selection and …

The genetic underpinnings that contribute to variation in olfactory perception are not fully
understood. To explore the genetic basis of variation in olfactory perception, we measured …

Previously, we mapped quantitative trait loci (QTL) affecting response to short-term selection
for abdominal bristle number to seven suggestive regions that contain loci involved in bristle …
