Life-History Evolution and the Genetics of Fitness Components in Drosophila melanogaster
Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …

Heritability is not evolvability
Short-term evolutionary potential depends on the additive genetic variance in the
population. The additive variance is often measured as heritability, the fraction of the total …

GEOGRAPHIC VARIATION IN DIAPAUSE INCIDENCE, LIFE‐HISTORY TRAITS, AND CLIMATIC ADAPTATION IN DROSOPHILA MELANOGASTER
In Drosophila melanogaster, exposure of females to low temperature and shortened
photoperiod can induce the expression of reproductive quiescence or diapause. Diapause …

Combining map** and arraying: an approach to candidate gene identification
A combination of quantitative trait locus (QTL) map** and microarray analysis was
developed and used to identify 34 candidate genes for ovariole number, a quantitative trait …

Sexually Antagonistic Cytonuclear Fitness Interactions in Drosophila melanogaster
Theoretical and empirical studies have shown that selection cannot maintain a joint nuclear-
cytoplasmic polymorphism within a population except under restrictive conditions of …

Testing an 'aging gene' in long‐lived Drosophila strains: increased longevity depends on sex and genetic background
Molecular advances of the past decade have led to the discovery of a myriad of 'aging
genes'(methuselah, Indy, InR, Chico, superoxide dismutase) that extend Drosophila lifespan …

Repeated loss of variation in insect ovary morphology highlights the role of development in life-history evolution
The number of offspring an organism can produce is a key component of its evolutionary
fitness and life history. Here we perform a test of the hypothesized trade-off between the …

Quantitative Trait Loci Affecting Phenotypic Plasticity and the Allometric Relationship of Ovariole Number and Thorax Length in Drosophila melanogaster
Environmental factors during juvenile growth such as temperature and nutrition have major
effects on adult morphology and life-history traits. In Drosophila melanogaster, ovary size …

Different mechanisms underlie phenotypic plasticity and interspecific variation for a reproductive character in drosophilids (Insecta: Diptera)
The insect ovary is a modular structure, the functional unit of which is the ovariole. Ovariole
number is positively correlated with potential reproductive output. Among drosophilids …
