Average gene diversity (H) was found to correlate with the level of outcrossing. No relationship was found between H and the phylogenetic status of a species. In all six species, the level of RFLP at a locus was a function of the position of the locus on the chromosome and the recombination rate in the neighborhood of the locus. Loci in the proximal chromosome regions, which show greatly reduced recombination rates relative to the distal regions, were significantly less variable than loci in the distal chromosome regions in all six species. Variation in recombination rates was also reflected in the haplotype divergence between closely related species; loci in the chromosome regions with low recombination rates were found to be diverged less than those in the chromosome regions with high recombination rates. This relationship was not found among the more distantly related species.<\/jats:p>","DOI":"10.1093\/genetics\/148.1.423","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T23:20:07Z","timestamp":1613172007000},"page":"423-434","source":"Crossref","is-referenced-by-count":145,"title":["Restriction Fragment Length Polymorphism and Divergence in the Genomic Regions of High and Low Recombination in Self-Fertilizing and Cross-Fertilizing Aegilops Species"],"prefix":"10.1093","volume":"148","author":[{"given":"Jan","family":"Dvor\u0159\u00e1k","sequence":"first","affiliation":[{"name":"Department of Agronomy and Range Science, University of California, Davis, California 95616"}]},{"given":"Ming-Cheng","family":"Luo","sequence":"additional","affiliation":[]},{"given":"Zu-Li","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Agronomy and Range Science, University of California, Davis, California 95616"}]}],"member":"286","published-online":{"date-parts":[[1998,1,1]]},"reference":[{"key":"2021042713195764000_R1","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1007\/978-1-4615-2383-3_6","article-title":"Polymorphism and divergence in regions of low recombination in Drosophila","volume-title":"Non-Neutral Evolution.
