%X the study area is highly heterogeneous, presenting the following ecological units: puna, valle calchaqu¨ª, valle de lerma and chaco. environment and topography can determine isolation and adaptation of human population, inducing genetic differentiation. in order to consider this fact, several genetic and demographic variables were studied. in puna, eritrocitary variants were analized in santa rosa de los pastos grandes, tolar grande and cobres, leucocitary in cobres, while constitutive heterochromatine was studied in tolar grande and cobres and strs in san antonio de los cobres and cobres. on the other hand, genetic demography was used to study opportunity for selection, reproductive isolation and endogamy in santa rosa de los pastos grandes, tolar grande, olacapato, san antonio de los cobres and cobres. in lerma valley, parameters for genetic demography were estimated in san agust¨ªn and chicoana; in the calchaqu¨ª valley in pichao and la alumbrera and in chaco constitutive heterochromatine was analized. data published by matson et al (1969) and pag¨¦s larraya et al (1978) were included. microevolutive processes studied (natural selection, genetic drift and gene flow), variability measures show strong and continued contact among populations, moderate differentiation and, in some cases, high endogamy.
