“…Since males of immigrant populations are likely to be the predominant source of gene introduction into the aboriginal populations, it was hoped that the information of mtDNA, because of its maternal inheritance (Hutchison et al, 1974;Giles et al, 1980;Case and Wallace, 1981), may give a clue to answer the question, whether the genetic similarity between the Ainu and the Mongoloid populations including the Non-Ainu Japanese is ascribed to gene flow.…”

SummaryRestriction enzyme fragment patterns of human mitochondrial DNA (mtDNA) were analyzed using total DNAs from the blood cells of 122 Japanese (Ainu and Non-Ainu) living in Hokkaido, northern Japan. Polymorphisms were detected and the mtDNAs were classified into eleven types using four enzymes, AvaII, HincII, HpaI and PvuII. The distribution of the mtDNA morphs was not significantly different between the Ainu and the Non-Ainu samples, supporting the views that the Ainu are genetically one of the Mongoloid populations.

“…In addition to its higher copy number, mtDNA is maternally inherited. 50 This maternal inheritance pattern confers the same mtDNA sequence, barring mutations, upon siblings and all their maternal relatives. This has important implications for the identification of individuals for which there is no antemortem comparison sample.…”

“…However, cytoplasmic genes are generally inherited uniparentally and may be a significant source of polymorphism among this subspecies. As described early this century (Correns, 1909), cytoplasmic inheritance is controlled mainly through the expression of genes contained within the mitochondrion inherited almost exclusively through maternal lineage in mammals (Hutchinson et al, 1974;Giles et al, 1980). Bovine dairy and beef production traits have been shown to vary in different maternal lineages and likely originate from polymorphic mitochondrial genotypes (Tess et al, 1987;Brown et al, 1988;Schutz et al, 1993Schutz et al, , 1994Mannen et al, 1998).…”

The American continent was colonized in the 16th century by Europeans who first introduced cattle of Bos taurus origin. Accounts register introduction of Bos indicus cattle into South America in the 19th and continuing through the 20th century, and most reported imports were males derived from the Indian subcontinent. In the present study we show, by using mitochondrial DNA (mtDNA) polymorphism, major participation of matrilineages of taurus origin in the American Zebu purebred origin, i.e., 79, 73 and 100% for the Nellore, Gyr and Brahman breeds, respectively. Moreover, we have created a restriction map identifying polymorphism among B. taurus and B. indicus mtDNA using three restriction enzymes. Results are discussed concerning American Zebu origins and potential use of this information for investigating the contribution of cytoplasmic genes in cattle production traits.
O continente americano foi colonizado no século XVI por europeus que fizeram as primeiras introduções de bovinos, de origem taurina. Os registros das primeiras importações de Zebus para a América do Sul datam do século XIX e continuam até o século XX, constituídos na maioria por machos do sub-continente indiano. Neste artigo, demonstramos, através dos estudos de polimorfismos no DNA mitocondrial (mtDNA), uma participação majoritária de matriarcas de origem taurina na formação do Zebu PO americano (79% dos animais analisados da raça Nelore, 73% na Gir e 100% na Brahman). Ainda, criamos um mapa de restrição com os polimorfismos descritos de três enzimas de restrição. Os resultados estão discutidos em termos da origem do Zebu americano e da aplicação deste conhecimento no estudo dos efeitos do genoma citoplasmático, nas características produtivas dos bovinos
