title: [Determination of the sample size and distribution of the ABO and Rh blood groups in Botucatu, Sã Paulo, Brazil (author's transl)].
abstract: In the present paper some statistical aspects referred to the distribution of the ABO and Rh blood groups were studied. The sample included 4,037 data, about white and no white persons, of both sexes, living in Botucatu. The results are presented with a calculation of the frequencies of the alleles responsible for the polymorphisms studied, the sample frequencies of the blood groups and their populations confidence-intervals estimates. The possibles interdependences for sex and color with the blood groups were verified by the chi2 test. The principal aim of the present study was to determine the ideal sample size. It was elaborated a table where are given populations sizes, samples sizes and the percentual relations between these values.
