Genetic Polymorphism in Evolving Population

TL;DR

This paper introduces a model for evolving populations that maintains genetic diversity through mutation, demonstrating survival and diversity preservation under environmental changes, with estimates aligning with natural observations.

Contribution

The study presents a novel model incorporating constant mutation rates to sustain genetic polymorphism in evolving populations.

Findings

Population survives with maintained diversity under environmental shifts

Model estimates match natural proportions of polymorphic and heterozygous loci

Mutation rate estimates are consistent with empirical data

Abstract

We present a model for evolving population which maintains genetic polymorphism. By introducing random mutation in the model population at a constant rate, we observe that the population does not become extinct but survives, keeping diversity in the gene pool under abrupt environmental changes. The model provides reasonable estimates for the proportions of polymorphic and heterozygous loci and for the mutation rate, as observed in nature.
