Chapter 22.2, Problem 1R

Summary Introduction

To review:

As per the Dobzhansky-Muller model, the divergence in the alleles at different gene loci leads to genetic incompatibility between the species. It needs to study the incompatibility which is less likely at the same locus between two alleles.

Given:

It is given that Dobzhansky-Muller model suggests that the divergence in the alleles is seen at different loci of a gene which can lead to genetic incompatibility between the species that possess such genes.

Introduction:

Dobzhansky-Muller model is a two-locus version model which studies the changes between the two lineages are from the same ancestor population, which gets divided from each other and evolve on their own. The new allele that generates, it becomes fixed in each descendent but the locus of the two alleles becomes different.
