title: An exact statistical test for the ABO system.
abstract: An exact test is proposed for the hypothesis stating that the ABO blood group distribution follows the Hardy-Weinberg law. The test is based on the conditional distribution of the observed phenotypic frequencies, given the estimated gene frequencies. For sample sizes of 20 or less, the exact test can be carried out with the aid of a table that lists the significant outcomes.
