| 摘 要： | 利用16个多态性较强、重复性好的随机引物对四川黑山羊多个种群的成年（1.5～2岁）黑山羊96只个体的血样DNA进行扩增,16个引物共扩增出170条多态的RAPD条带.对给定的标记,将“有带（1）”、“无带（0）”两类个体看作独立样本,采用SPSS软件的Compare Means中的Independent-samples T Test来比较两样本各数量性状平均值的差异.并根据两独立样本间个体表型值的分布筛选与性状真实关联的分子标记.结果表明,在黑山羊群体中共筛选到5个分子标记分别与不同性状相关,其遗传基础可能是该标记与控制性状的QTL或主基因连锁. |

| Abstract: | 16 random primers with sufficient polymorphism and reproducible patterns were selected to amplify the blood DNA from 96 adult Sichuan black goat at age of 1.5 to 2 years old.170 polymorphic RAPD bands were produced with the 16 primers.These bands were recorded in the form of 1(presence of band) and 0(absence of band).To a specific marker,the individuals with different polymorphic bands are treated as different samples.The difference of the average for quantitative traits of the two samples were compared with Independent-samples T Test by using SPSS software.Molecular markers having true correlation with traits were selected according to the distribution of the individual phenotypic value of two independent samples.The results showed that 5 molecular markers in the black goat population were related to different phenotypic traits.It is suggested that this marker may have linkage relationship with the quantitative trait loci or the major gene controlling this trait. |
