Assortative mating traits can drive speciation. Selection against unfit hybrids, combined with assortative mating, can cause populations to diverge, especially with strong genetic effects or direct selection on the trait.

Area of Science:

  • Evolutionary Biology
  • Population Genetics
  • Speciation Research

Background:

  • Assortative mating traits, like flowering time or body size, can lead to reproductive isolation in hybridizing populations.
  • Understanding the mechanisms driving population divergence is crucial for comprehending speciation processes.

Purpose of the Study:

  • To investigate whether selection against unfit hybrids can promote divergence in assortative mating traits between populations.
  • To model the interplay between assortative mating, gene flow, and selection in shaping population divergence.

Main Methods:

  • Development of a haploid analytical model for a population receiving gene flow.
  • Incorporation of partial pre-zygotic isolation via assortative mating on polygenic traits.
  • Inclusion of post-zygotic isolation through selection against genetic incompatibilities (epistasis).

Main Results:

  • Divergence in assortative mating trait means requires direct selection or genes of large effect; otherwise, gene flow homogenizes traits.
  • Equilibrium divergence is a balance between direct selection on the trait and introgression.
  • Selection against hybrid incompatibilities reduces effective migration, enhancing trait divergence.

Conclusions:

  • Assortative mating, coupled with selection against unfit hybrids, can contribute to population divergence and potentially speciation.
  • The strength of direct selection on the trait and the impact of genetic incompatibilities are key factors influencing divergence.
  • This model provides insights into the role of assortative mating in the broader context of speciation.
