Genetics of species differences

Article Abstract:

Genetics of species differences have been studied by looking at courtship songs of Drosophila pseudoobscura and D. persimilis. The genetic basis of the difference is examined in two courtship song elements, interpulse interval and intrpulse frequency using 15 molecular markers. Song differences were associated with at least two or three genomic regions. Interpulse interval is strongly associated with mating success to D. pseudoobscura females, but intrapulese frequency is associated with mating success to D. persimilis females. Implications are discussed.

Reinforcement and other consequences of sympatry

Article Abstract:

This article discusses species mating discrimination between sympatric and allopatric taxa. In the former, reinforcement process prevents maladaptive hybridization. New approaches to better understand the reinforcement process using recent advances in molecular population genetics and the genetic tools are presented.

Multiplicity of infection and the evolution of hybrid incompatibility in segmented viruses

Article Abstract:

The many types of infections that exist as they relate to evolution of hybrid incompatibility in segmented viruses are discussed. Mathematical and computer models of the processes that influence hybrid incompatibility between diverging strains are presented. Multiplicity of infection is seen to be the key factor.
