摘要：

The theory, construction and optimization of a model of chromosome pairing in triploid hybrids are re-examined and the model reconstructed. A new approach to optimization is described that removes a bias in the estimation of x, the measure of relative affinity, by weighting the observed and calculated meiotic figure frequencies by the number of chromosomes in each figure type. The amended analysis is compared with its antecedent and with other models.
