ABSTRACT
The relationship between average heterozgosity and genetic distance estimates was evaluated among 13 Amazonian Indian tribes, using data of 24 genetic systems. The results showed that the genetic distances were negatively correlated with the average heterozygosity for each pair of tribes. The relationship between genetic and geographic distances was also examined, but no significant correlation was observed between these measures. The negative correlation between genetic distance and average heterozygosity may be attributed to the bottleneck effect or inbreeding due to the small effective size of several tribes, reducing the heterozgosity and increasing the genetic distance between them.
