| 摘 要： | 应用极大似然法和EM算法提出了关于两个位点主基因控制的质量．数量性状的遗传分析方法，参照质量性状两位点互作在F_2代的分离比率建立了7种遗传假设及其似然比测验的程序，讨论了应用这一方法时应注意的几个问题．

| Abstract: | The genetic analysis procedure based on maximum likelihood methed for Qualitative-Quantitative traits controlled by two major gene loci is proposed.This procedure can test seven genetic hypotheses about two major gene interaction by using EM algorithm and likelihood ratio test.Several problems about application of the method are discussed. |
