Abstract:
A total of 337 Kaingang and Guarani Indians from two localities were studied in relation to 18 protein genetic loci. In one of the localities, members of these two groups live side by side but show little genetic similarity, emphasizing the influence of cultural factors in the mating behavior of human groups. Integrating the present results with previous ones, it was verified that the genetic relationships among six Kaingang populations do not follow the pattern expected from their geographical distribution. Comparisons made with three other Ge˜-speaking tribes indicate that the Kaingang did not separate well from them. Most (96%) of the variability in the six polymorphic systems considered occur at the intrapopulational level. Am. J. Hum. Biol. 9:505-512, 1997. © 1997 Wiley-Liss, Inc.
