Population Genomic Analysis Reveals No Evidence for GC-Biased Gene Conversion in Drosophila melanogaster

摘要: Gene conversion is the nonreciprocal exchange of genetic material between homologous chromosomes. Multiple lines evidence from a variety taxa strongly suggest that gene events are biased toward GC-bearing alleles. However, in Drosophila, data have largely been indirect and unclear, with some studies supporting predictions aG C-biased model other showing contradictory findings. Here, we test whether GC-biased Drosophila melanogaster using whole-genome polymorphism divergence data. Our results provide no support for thus this process unlikely to significantly contribute patterns system.
