Triploid vertebrates usually circumvent this problem through either asexuality or some forms of hybridogenesis, including meiotic hybridogenesis that involve a reproductive community of different ploidy levels and genome composition. Batura toads (\n                    <jats:italic>Bufo baturae<\/jats:italic>\n                    ; 3\n                    <jats:italic>n<\/jats:italic>\n                    = 33 chromosomes), however, present an all-triploid sexual reproduction. This hybrid species has two genome copies carrying a nucleolus-organizing region (NOR+) on chromosome 6, and a third copy without it (NOR\u2212). Males only produce haploid NOR+ sperm, while ova are diploid, containing one NOR+ and one NOR\u2212 set. Here, we conduct sibship analyses with co-dominant microsatellite markers so as (i) to confirm the purely clonal and maternal transmission of the NOR\u2212 set, and (ii) to demonstrate Mendelian segregation and recombination of the NOR+ sets in both sexes. This new reproductive mode in vertebrates (\u2018pre-equalizing hybrid meiosis\u2019) offers an ideal opportunity to study the evolution of non-recombining genomes. Elucidating the mechanisms that allow simultaneous transmission of two genomes, one of Mendelian, the other of clonal inheritance, might shed light on the general processes that regulate meiosis in vertebrates.\n                  <\/jats:p>","DOI":"10.1098\/rspb.2011.1738","type":"journal-article","created":{"date-parts":[[2011,10,12]],"date-time":"2011-10-12T05:52:44Z","timestamp":1318398764000},"page":"1293-1299","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":54,"title":["Simultaneous Mendelian and clonal genome transmission in a sexually reproducing, all-triploid vertebrate"],"prefix":"10.1098","volume":"279","author":[{"given":"Matthias","family":"St\u00f6ck","sequence":"first","affiliation":[{"name":"Department of Ecology and Evolution, University of Lausanne, Biophore, 1015 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Ustinova","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Zoologisches Institut I, Lehrstuhl f\u00fcr Zell- und Neurobiologie, Haid-und-Neu-Street 9, 76131 Karlsruhe, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Betto-Colliard","sequence":"additional","affiliation":[{"name":"Department of Ecology and Evolution, University of Lausanne, Biophore, 1015 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manfred","family":"Schartl","sequence":"additional","affiliation":[{"name":"Lehrstuhl f\u00fcr Physiologische Chemie I, Theodor-Boveri-Institut, Biozentrum, University of W\u00fcrzburg, Am Hubland, 97074 W\u00fcrzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig","family":"Moritz","sequence":"additional","affiliation":[{"name":"Museum of Vertebrate Zoology, University of California, 3101 Valley Life Sciences Building no. 3160, Berkeley, CA 94720-3160, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas","family":"Perrin","sequence":"additional","affiliation":[{"name":"Department of Ecology and Evolution, University of Lausanne, Biophore, 1015 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2011,10,12]]},"reference":[{"key":"e_1_3_2_2_2","first-page":"3","article-title":"Versuche \u00fcber Pflanzenhybriden [Experiments on plant hybridization]","volume":"4","author":"Mendel G.","year":"1866","journal-title":"Verh.
