Summary

Genetic variation in Drosophila melanogaster affects fertility through complex genotype interactions. A novel selection mode, alloprocoptic selection, favors dissimilar genotypes, promoting genetic diversity.

Area of Science:

  • Evolutionary biology
  • Population genetics
  • Genetics

Background:

  • Genetic variation at enzyme-coding loci influences organismal fitness.
  • Reproductive success in Drosophila melanogaster is influenced by the genotypes of both mating partners.

Purpose of the Study:

  • To investigate the fitness effects of genetic variation at three enzyme-coding loci in Drosophila melanogaster.
  • To characterize the nature of genotype-by-genotype interactions affecting female fertility.
  • To identify and name a novel mode of selection contributing to genetic polymorphism.

Main Methods:

  • Studied genetic variation at three enzyme-coding loci in Drosophila melanogaster.
  • Analyzed female fertility based on female and male genotypes.
  • Quantified fitness effects of specific homozygous and heterozygous combinations.

Main Results:

  • Female fertility depends on the combined genotypes of both male and female.
  • Significant genotype-by-genotype interactions were observed, preventing prediction from average fertilities.
  • A novel selection mode, termed alloprocoptic selection, was identified where dissimilar homozygous genotypes yield higher fertility.
  • This selection pattern was observed at two of the studied loci.

Conclusions:

  • Genotype interactions significantly impact fitness and can lead to multiple stable evolutionary equilibria.
  • Alloprocoptic selection, favoring the association of dissimilar genotypes, contributes to maintaining genetic polymorphism in natural populations.
  • Understanding these complex genetic interactions is crucial for predicting evolutionary trajectories and maintaining biodiversity.
