Resumo: | The objective of this work was to evaluate, through a polymorphism in the ND5 gene of the bovine mitochondrial DNA, the frequency of Bos taurus indicus mtDNA individuals in a sample of Nellore purebred origin animals (n = 69) and crossbred animals originated from crosses of European sires and Nellore purebred origin females (n = 275). Only 2.26% (8/354) of the animals presented Bos taurus indicus mtDNA. The high frequency of Bos taurus taurus mtDNA in these animals can be a consequence of selection, once the animals studied are originated from selected lineages of high performance for meat production. |

Apenas 2,26% (8/354) dos animais apresentaram mtDNA Bos taurus indicus. A alta freqüência de mtDNA Bos taurus taurus nesses animais pode ser reflexo de seleção, uma vez que os animais estudados se originam de linhagens selecionadas para alto desempenho de produção de carne.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCuri, Rogério AbdallahMota, Lígia Souza Lima Silveira daSilveira, Antônio Carlos2007-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7685Pesquisa Agropecuaria Brasileira; v.42, n.8, ago. 2007; 1203-1205Pesquisa Agropecuária Brasileira; v.42, n.8, ago. 2007; 1203-12051678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/7685/4604info:eu-repo/semantics/openAccess2014-10-13T17:23:20Zoai:ojs.seer.sct.embrapa.br:article/7685Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-13T17:23:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
