We compared the morphology of their sperm with that of normal diploid Zebra Finches and examined eggs resulting from a triploid male and diploid female pairing to investigate whether triploid Zebra Finches can reproduce. The majority (78%) of the triploids' spermatozoa had malformed sperm heads, which were 60% larger, and all examined eggs (n = 42) were infertile. Our results tentatively suggest that triploid ZZZ Zebra Finches cannot reproduce, and thus represent a rare evolutionary dead-end.</dcterms:abstract> <dc:language>eng</dc:language> </rdf:Description> </rdf:RDF>
