Abstract

Three Amerindian populations, two from Rondonia, Brazil (Karitiana and Rondonia Surul), and one from Campeche, Mexico (Mayan), were typed for up to 30 nuclear restriction fragment length polymorphisms (RFLPs). Heterozygosities, both observed and expected, were compared with those of Europeans. Average heterozygosity is reduced among these Amerindians (relative to that of Europeans) by 7.0% (Mayan) to 27.1% (Karitiana). This amount of heterozygosity in the nuclear DNA is nevertheless high enough that it is unlikely that there was a severe or prolonged bottleneck.
