Neutral polygenic characters in subdivided populations are analyzed. Gametic disequilibrium significantly impacts group variance, but not its expectation, revealing polygenic traits offer substantial population relationship insights.

Area of Science:

  • Population genetics
  • Quantitative genetics

Background:

  • Subdivided populations exhibit genetic variation.
  • Understanding genetic drift and gene flow is crucial for evolutionary studies.

Purpose of the Study:

  • To investigate the behavior of neutral polygenic characters in subdivided populations using a migration matrix model.
  • To assess the impact of gametic disequilibrium on population differentiation.

Main Methods:

  • Utilized a migration matrix model to simulate population dynamics.
  • Analyzed the variance and expectation of among-group variance for polygenic characters.
  • Compared theoretical predictions with empirical data on dermatoglyphic and anthropometric traits.

Main Results:

  • Gametic disequilibrium strongly influences the variance among population groups, but not its expected value.
  • The variance of among-group variance is substantial and independent of the number of loci.
  • Polygenic characters provide as much information on population relationships as single-locus markers.

    • Conclusions:

    • Neutral polygenic characters are valuable for inferring population structure.
    • The study provides a theoretical framework for using quantitative traits in population genetics.
    • Empirical data from Bougainville islanders support the theoretical model.
