After analyzing glutinous rice waxy gene sequence reported by previous studies, two pairs of dominant and codominant STS molecular markers based PCR were designed for distinguishing glutinous rice, according to the distinctions between glutinous rice wx gene and nonglutinous rice Wx gene. Moreover, the whole sequences of the two Wx genes of nonglutinous rice reported by others were also aligned, and another two pairs of dominant STS molecular markers were designed to discriminate Wxa from Wxb based on the special site between the two genotypes. Then, corresponding rice genotypes were identified by the established new markers.

通过对前人公布的糯性水稻蜡质基因全序列测定结果的分析，根据糯性水稻与非糯性水稻蜡质基因序列位点的差异，设计了两个基于PCR扩增反应的可特异识别糯性水稻的显性和共显性STS分子标记；同时在前人公布的非糯性水稻蜡质基因的不同类型的全序列比对分析的基础上，选取了两种基因型特定的差异位点，设计了两个基于PCR扩增反应用于特异识别这两种Wx基因的显性STS分子标记，并用新建立的标记对相应的水稻基因型进行了检测。

Inthe paper, we study the relation of pairs of lines and pairs of needles, and two results ofintegral formulas are gained. Thus, the geometric probability problem is solved. Also.we give a solution to the problem: pick two points randomly in a convex body K anddraw two lines passing through two points.
