The classical method of approaching this problem is done through the chi-square test that often leads to the verification of the equilibrium hypothesis. In the present work, a Bayesian analysis was developed involving hypothesis testing, estimation and credibility intervals to test this balance. Data on M, MN and N blood groups from the MNS system were used on samples from two populations, one from Brazilians and one from North Americans, obtained by Beiguelman (1977). The HardyWeinberg equilibrium adhesion chi-square test was performed, where the acceptance of the Hardy-Weinberg equilibrium hypothesis was confirmed. By Bayesian analysis, the rejection of the Hardy-Weinberg equilibrium hypothesis was confirmed, mainly by the Bayes factor. Our primary concern was to develop a Bayesian technique as an alternative to testing HardyWeinberg equilibrium using the MNSs blood sample data. The result obtained may encourage researchers mainly in the field of biological sciences to practice Bayesian Methodology, as an alternative in statistical tests.</p>}, number={1}, journal={Brazilian Journal of Biometrics}, author={CUNHA FILHO, Moacyr and CRUZ, David Venancio da and OLIVEIRA, Emídio Cantídio Almeida de and PISCOYA, Victor Cassimiro and MOREIRA, Guilherme Rocha and CUNHA, Ana Luiza Xavier and ARAÚJO FILHO, Renisson Neponuceno de}, year={2020}, month={Mar.}, pages={69–78} }
