An EM algorithm procedure is presented for the maximum-likelihood estimation of mating system parameters of mixed mating system models for both angiosperms and gymnosperms. One advantage of the procedure is the ability to accommodate any number of alleles in the mature population and pollen pool. Estimates of the outcrossing rate ([Formula: see text]) derived from the model are bounded strictly within the natural biological range (i.e., 0 ≦ [Formula: see text] ≦1).
本文提出了一种 EM 算法程序，用于对被子植物和裸子植物的混合交配系统模型的交配系统参数进行最大似然估计。该程序的一个优点是能够适应成熟群体和花粉库中任何数量的等位基因。从模型中得出的异交率([Formula: see text])估计值严格限制在自然生物学范围内（即 0 ≦ [Formula: see text] ≦1）。
