Studies on polymorphism segregation in Northeastern Brazil. I: analysis of multiloci

ABSTRACT

The population dynamics of several polymorphic systems were studied in two samples originated from Northeastern Brazil. A high frequency of gametic disequilibrium values between loci pairs was observed, which could be explained by the recent history of racial admixture of the population. However, for multiple loci segregation, no significant differences between the expected and observed numbers of homozygotes could be detected, indicating a lack of biological mechanisms acting on these complex genetic structures.
