Genetic variation at seven red blood cell alloantigen, blood group loci and 10 biochemical genetic loci was examined in 102 Pantaneiro horses from the Pantanal region of Brazil and compared to that of other domestic horse breeds. Measures of both individual genic variation and populational genetic diversity within the Pantaneiro were near the average for domestic horse breeds. From the standpoint of genetic conservation there is no immediate concern for loss of variation within the Pantaneiro. Analysis of genetic relationship showed that the Pantaneiro was clearly of Iberian Peninsula descent and that it was most closely related to other Brazilian breeds. Examinou-se a variação genética de 102 cavalos Pantaneiros da região do Pantanal, Brasil, usando sete locos de grupos sanguíneos e 10 locos genéticos bioquímicos. As medidas de variação genética individual e diversidade genética populacional dentro da população de cavalos Pantaneiros foram próximas da média encontrada para as raças de cavalos domésticos. Do ponto de vista de conservação genética, não há preocupação imediata com relação à perda de variação dentro da raça. Análises das relações genéticas mostraram claramente que o cavalo Pantaneiro descende de cavalos da península Ibérica e que ele é estreitamente relacionado com as demais raças brasileiras
