The SSRs are multiallelic codominant genetic markers. 以此为基础发展起来的SSR标记是一种共显性分子标记，遗传多态性丰富。
The phenotype expressed depends on whether alleles are dominant, recessive or codominant. 表达的表现型取决于等位基因是显性的、隐性的还是共显性的。
As a codominant genetic marker,restriction fragment length polymorphisms,referrd as RFLPs,has been widely applied to the prenatal diagnosis of some genetic dise ases. 摘要 限制性酶切片段长度多态性（RFLP）作为共显性的遗传标记，已广泛应用于遗传病的产前诊 断。
The Polymorphisms of Es-1 ,Es-2,Es-3,Po and Prt was determined by 2,2,2,2 and 3 codominant alleles and exhibited 3,3,3,3 and 6 phenotypes. respectively. X~2检验表明,哈尔滨白兔在Es-1、Es-2、Es-3、Po和Prt位点均处于平衡状态,其它各群体各有自己的平衡位点和非平衡位点。
Abstract: Microsatellites are composed of simple tandem repeats of nucleotides primarily in non-coding gene sequences.The number of repeats is inherited as a codominant trait. 摘 要： 微卫星主要是指由非编码基因序列核苷酸的简单串联重复，其重复的数目呈共显性遗传。
Both of them, to be codominant markers, can identify false hybrids not only from selfed seeds of male and female but also from foreign pollen and mechnical contamination. 两引物均能在父母本中扩出特异带，为共显性标一记，不仅能够鉴别杂交种中混杂的母本自交的种子和父本的种子，还可鉴别部分由于外来花粉或机械混杂等造成的假杂种。
