家蚕标记基因位点与数量性状基因位点重组参数的最大似然估计法

MAXIMUM LIKELIHOOD ESTIMATES OF RECOMBINATION PARAMETERS BETWEEN A MARRER GENE LOCUS AND QUANTITATIVE TRAIT LOCUS IN THE SILKWORM(BOMBYX MORI)

利用分离世代群体（ＢＣ＿１或Ｆ＿２），估算家蚕标记基因位点与数量性状基因位点重组参数的最大似然估计法，求解似然方程组的ＥＭ迭代算法。通过１２０次计算机模拟和一个生产实例验证了方法的可行性。

A method is described to obtain maximumum likelihood estimates of recombition pa -rameters between a marker gene locus and a quantitative trait locus with the segregationgererations in the silkwrom, And the use of EM iterative algorithm to solve the set oflikelihood quations is proposed.In the paper the accuracy of this method was investigat-ed by l20 of computer simulations and l biological example. The results show that thismethod is practical.
