In Saccharomyces cerevisiae, recombination events occurring between allelic genes located on homologous chromosomes are often associated with heteroduplex formation. We found that recombination events between repeated genes on nonhomologous chromosomes (ectopic events) are also associated with the formation of heteroduplexes, indicating that classical and ectopic recombination events involve similar mechanisms.
