分离比率

提出以EM算法对主基因的分离比率、基因效应、微基因的遗传方差等进行极大似然估计以及以似然比方法测验有关遗传假设的程序。

The maximum likelihood estimation of segregating ratios and the effects of major gene as well as the polygenic variation is proposed through the EM algorithm , and the test of corresponding genetic hypotheses by the likelihood ratio .

F2代种皮性状黑色与红色分离比率为9∶7，说明漯珍一号黑种皮由2对显性互补基因控制。

All the F_1s had black kernels and in F_2 generation segregation in kernel color occurred with the ration of 9 black ∶ 7 red , suggesting that the character of black epidermis is controlled by two dominant complementary genes .

在BCF1（esp1/日本晴//esp1）共1056株群体中，正常植株有542株，突变株524株，分离比率符合1：1。

In the total 1056 plants of BCF1 ( esp1 / Nipponbare / / esp1 ) population , there were 542 normal plants and 514 mutant plants respectively , that was good fit to 1:1 ratio .

而9MGV-6W胞质体组和12MGV-6W胞质体组成熟卵母细胞染色单体提早分离的比率则明显增加。

However , the rates of the matured oocytes with premature chromatid separation increased for group 9M GV-6W cytoplast and group 12M GV-6W cytoplast .

三种大豆分离蛋白的7S/11S比率和变性热焓类似，但表面疏水性和混浊度却明显不同。

The 7S / 11S ratio and denaturation enthalpy of soy protein isolates were similar but surface hydrophobicity and turbidity were different remarkably .

同时，将理论结果和实验结果进行比较，得到了样品中分离铜的有效比率。

Meanwhile , theoretical results are compared with experimental results so that the author can get the effective ratios of separate copper in samples .
