There was nearly an equal number of one-nucleolate and two-nucleolate tadpoles in those produced from two pairs of males and females just as in the tadpoles collected from the field. The one-nucleolate and two-nucleolate tadpoles collected from the field as well as those raised in the laboratory were administered estrogen or androgen in order to obtain sex-reversed frogs. Masculinization occurred in a greater or less degree in many of one-nucleolate females administered estrogen or androgen at the tadpole stage. Seven of them administered estrogen or androgen attained sexual maturity. Offspring were obtained from two mature sex-reversed genetic females administered estrogen. Feminization also occurred to a certain degree in many of the juvenile two-nucleolate males administered estrogen at the tadpole stage. Of the 1067 offspring obtained from the two mature sex-reversed genetic females (1-nu) mated with three normal females (1-nu), 243 (22.8%) had no nucleolus, 525 (49.2%) had one nucleolus, and 299 (28.0%) had two nucleoli, when examined at the neurula, tail-bud and tadpole stages. While all the anucleolate individuals did not live beyond the tail-bud stage, the one- and two-nucleolate individuals mostly survived normally and became females and males, respectively. It was confirmed that the sex chromosomes are of the ZZ/ZW-type in Buergeria buergeri and that the nucleolar organizer is situated in the Z chromosome and inherited as a Mendelian character.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Institute for Amphibian Biology, Hiroshima University"}]},"item_1617186660861":{"attribute_name":"Date","attribute_value_mlt":[{"subitem_date_issued_datetime":"2006-03-21","subitem_date_issued_type":"Created"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186819068":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15027/373","subitem_identifier_reg_type":"JaLC"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0386-3166","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA00837669","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"213"}]},"item_1617187056579":{"attribute_name":"bibliographic_information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1987-12","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"238","bibliographicPageStart":"213","bibliographicVolumeNumber":"9","bibliographic_titles":[{"bibliographic_title":"Scientific report of the Laboratory for Amphibian Biology"},{"bibliographic_title":"Scientific report of the Laboratory for Amphibian Biology"}]}]},"item_1617258105262":{"attribute_name":"item_1617258105262","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617349709064":{"attribute_name":"Contributor","attribute_value_mlt":[{"contributorNames":[{"contributorName":"国立情報学研究所"}]}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2006-03-21"}],"displaytype":"simple","filename":"KJ00000017095.pdf","filesize":[{"value":"2.3 MB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2016116/files/KJ00000017095.pdf"},"version_id":"cd47e8f1-9436-4c47-a6e8-c91117248362"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"373"},"item_title":"Sex Determining Mechanism in Buergeria buergeri (SCHLEGEL) : II.
