摘　　要：　用推广的ITO方法推出复等位基因平衡群体中母子间及全同胞对子间基因型联合概率分布列的矩阵表达;给出了母子间及全同胞对子间的联合信息熵、互信息,并定义了各自的信息关联系数;与统计学研究相比表明,信息学的方法可使复等位基因平衡群体中亲属关系的研究成为可能。Matric expression between female genotypes and its descendant genotypes and between full antithetical couplet were discussed with extended ITO;And the associated genotype entropy and interentropy and the information coefficient of correlation among them were defined.The results show that informatics method can make possible the research on the kinship in alleles equilibrium population.
