Mechanisms of genetic exchange within the chromosomal inversions of Drosophila pseudoobscura.

Abstract excerpt

We have used the inversion system of Drosophila pseudoobscura to investigate how genetic flux occurs among the gene arrangements. The patterns of nucleotide polymorphism at seven loci were used to infer gene conversion events between pairs of different gene arrangements. We estimate that the average gene conversion tract length is 205 bp and that the average conversion rate is 3.4 x 10(-6), which is 2 orders of...
