They are morphologically identical but H. versicolor is a tetraploid. They can be identified acoustically by the male\u2019s advertisement mating call, which has a pulse repetition rate that has twice as many pulses per second in the diploid species, H. chrysoscelis. We used isozymes, microsatellite DNA alleles, and mitochondrial cytochrome b sequences to test the hypothesis that gene exchange occurs between the diploid and tetraploid species in sympatric populations. Each method provided results that are best explained by occasional hybridization of female H. versicolor and male H. chrysoscelis. We propose that H. versicolor first arose from an autotriploid H. chrysoscelis female that produced unreduced triploid eggs. After H. versicolor became established, genes could be passed from H. chrysoscelis to H. versicolor in sympatric populations when these species hybridize. Their F<jats:sub>1<\/jats:sub> female progeny produce unreduced triploid eggs that are fertilized by haploid H. chrysoscelis sperm to reconstitute H. versicolor. Genes can be passed from diploid H. chrysoscelis to tetraploid H. versicolor in sympatric populations. <\/jats:p>","DOI":"10.1139\/gen-2020-0031","type":"journal-article","created":{"date-parts":[[2020,8,13]],"date-time":"2020-08-13T21:35:43Z","timestamp":1597354543000},"page":"547-560","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":14,"title":["Revisiting the evolution of the North American tetraploid treefrog (<i>Hyla versicolor<\/i>)"],"prefix":"10.1139","volume":"63","author":[{"given":"James P.","family":"Bogart","sequence":"first","affiliation":[{"name":"Department of Integrative Biology, University of Guelph, Guelph, ON N1G 2W1, Canada."},{"name":"Department of Integrative Biology, University of Guelph, Guelph, ON N1G 2W1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Burgess","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology, University of Guelph, Guelph, ON N1G 2W1, Canada."},{"name":"Department of Integrative Biology, University of Guelph, Guelph, ON N1G 2W1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinzhong","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology, University of Guelph, Guelph, ON N1G 2W1, Canada."},{"name":"Department of Integrative Biology, University of Guelph, Guelph, ON N1G 2W1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2017.2667"},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1558-5646.2010.01163.x"},{"key":"refg3\/ref3","unstructured":"Bogart, J.P. 1972.
