Quantitative genetic tests of recent senescene theory: age-specific mortality and male fertility in Drosophila melanogaster

Article Abstract:

According to the Quantitative genetic models of aging, additive genetic variance for fitness components should increase with age. A large-scale quantitative genetic analysis of age-specific mortality and fertility in virgin male Drosophila melanogaster carried out to determine whether the decline in reproductive effort at late ages leads to a decrease in the genetic variance in mortality is presented.

The Hill-Robertson effect: evolutionary consequences of weak selection and linkage in finite populations

Article Abstract:

A paper reviewing major concepts and simulation results associated with the Hill-Robertson effect is presented. The focus is on weak and moderate mutations as they contain a large number of weakly selected sites and these sites are likely to be physically clustered in exons and regulatory regions.

Copy number of P elements, KP/full-sized P element ratio and their relationships with environmental factors in Brazilian Drosophila melanogaster populations

Article Abstract:

The P transposable element copy numbers and the KP/full-sized P element ratios were determined with the help of eight Brazilian strains of Drosophila melanogaster. The full-sized P and KP elements were the predominant classes of elements in all the strains.
