Loss of genetic diversity can hinder adaptation to changing environments and consumer demands. K-means clustering on the genomic relationship matrix was used to stratify 20,099 selected candidates into five clusters. These clusters were shown to be different through expected inbreeding within- and across cluster, the fixation index (Fst), and genetic correlations for stature between clusters. Expected inbreeding within cluster was mostly higher than across-cluster. The average Fst across cluster was 0.03. Genetic correlations ranged from <0.50 to >0.90. Families were formed by tracing pedigrees of each cluster back for 10 generations. Allele frequency changes over generations were evaluated. Polygenic shifts, selective sweeps, hitch-hiking, and epistasis were observed. The Replicate Frequency Spectrum was used to measure genetic redundancy. Results show that sub-populations within the breed have developed differently over time.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wageningen Academic Publishers","subitem_publisher_language":"en"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3920/978-90-8686-940-4_236","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Creative Commons Attribution 4.0 International","subitem_rights_language":"en","subitem_rights_resource":"https://creativecommons.org/licenses/by/4.0/"}]},"item_2_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Steyn, Y.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Lawlor, T.J.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Tsuruta, S.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Masuda, Y.","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Legarra, A.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Lourenco, D.A.L.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Misztal, I.","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2024-03-26"}],"displaytype":"detail","filename":"M-2023-122_masuda.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://rakuno.repo.nii.ac.jp/record/2000231/files/M-2023-122_masuda.pdf"},"version_id":"f0e9c26a-0cbd-4d67-bcdb-63abdd70fd6c"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Investigating genetic redundancy as a source of genetic diversity and adaptability in the U.S. Holstein breed","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Investigating genetic redundancy as a source of genetic diversity and adaptability in the U.S. Holstein breed","subitem_title_language":"en"}]},"item_type_id":"2","owner":"10","path":["14"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-26"},"publish_date":"2024-03-26","publish_status":"0","recid":"2000231","relation_version_is_last":true,"title":["Investigating genetic redundancy as a source of genetic diversity and adaptability in the U.S. Holstein breed"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-03-27T01:51:22.056338+00:00"}
