Comparação cromossômica intrapopulacional da espécie Tayassu tajacu criada em cativeiro
(Universidade Federal do Pará, 2005-04-13) SOUZA, Patrícia Carvalho de; BURBANO, Rommel Mario Rodriguéz; http://lattes.cnpq.br/4362051219348099
The collared peccary (Tayassu tajacu) is found from southern United States to northern Argentina. In Brazil, it ranges all over the country and is a source of meat for local people. Thus, a cytogenetic analysis is an important tool to evaluate reproductive efficiency at animals breeding in captivity that in order to commercialization. The aim of this study was to determine the chromosomal number of this specie from animals breeding in captivity of different populations. The animals utilized in this work were from different Brazilian populations: 6 animals from Mossoró (RN), 1 from Ipixuna (PA) and 4 from Uruará (PA). Metaphase chromosomes were prepared from cultured blood lymphocytes, following standard procedures. The results showed the same karyotypic pattern found for others authors (2n = 30 chromosomes and FN = 48), although, not any differences were found among these populations. But, they showed the same South American pattern, however, chromosomal polymorphism were found when compared to others populations, in Brazil and others countries (United States and French Guiana).
