Summary:Brazilian Centro-Oeste region settlement was derived from national internal migrations of already mixed individuals. A Brazilian peculiarity, which occurred during the population formation, was the directional mating between European males and Amerindian or African females. Seeking the improvement of the knowledge about Goiás and Federal District population history, we studied the distribution of Y-haplogroups in samples of these populations. According to the data obtained, Federal District genetic diversity rate was greater than Goiás, which reflected a small divergence between these two neighbors' populations but statistically unsupported (P=0.0524). The European contribution was similar in both population and greater than African and Amerindian ones. In Federal District, a little contribution from Japan was also observed.
