Is there a difference among human populations in the rate with which mutation produces electrophoretic variants?

RESUMO

Data are summarized that suggest that tropical-zone/tribal/nonindustrialized populations have higher frequencies of certain types of protein variants than temperate-zone/civilized/industrial populations, and it is demonstrated that these differences are not an artifact produced by the contagious type of sampling used with respect to tribal populations. Evidence is reviewed that suggests that a possible explanation of this difference is higher mutation rates in the tribal populations studied.
