This study introduces a computer model for simulating population genetics, tracking polygenes and mobile genetic elements (MGEs) under selection. The model analyzes complex genetic dynamics and interactions not easily measured experimentally.

Area of Science:

  • Population genetics
  • Computational biology
  • Genomics

Context:

  • Understanding the interplay between polygenes and mobile genetic elements (MGEs) is crucial for evolutionary biology.
  • Previous models often lacked the stochasticity and comprehensive genetic processes needed to accurately simulate population dynamics.

Purpose:

  • To develop a stochastic computer system for simulating population dynamics of interacting polygene patterns and MGEs under selection for quantitative traits.
  • To provide a tool for analyzing parameters not easily estimated experimentally, such as allele frequencies, fixation proportions, and heritability.

Summary:

  • A Monte Carlo simulation system was created to model population genetics, incorporating recombination, transpositions, excisions, genetic drift, and selection.
  • The system accounts for random changes and deterministic trends in finite populations, enabling detailed analysis of genetic elements and their interactions.

Impact:

  • Enables in-depth analysis of population genetic parameters like allele frequencies, heterozygosity, inbreeding coefficient, and heritability.
  • Facilitates testing hypotheses regarding polygene-MGE interactions and their influence on quantitative trait evolution.
