Zmu-1:DHP近交系豚鼠的培育及其分子遗传结构初步鉴定
Breeding of Zmu-1:DHP inbred strain guinea pig and preliminary analysis of molecular genetic structure of the strain
摘要
Abstract
Objective To breed a guinea pig inbred strain and set up a method for detection of the microsatellite markers of genetic structure in guinea pigs. Method Using inbreeding methods we try to breed the Zmu-1:DHP inbred strain. With 15 pairs of polymorphism microsatellite primers, the genetic homozygosity of Zmu?1:DHP inbred strain,Zmu?1:DHP outbred strain and Zmu?2:DHP inbred strain ( as control) were examined by PCR. Results After breeding for 13 years, 8 sublines of Zmu?1:DHP inbred strain ( >20 generations) were bred. After identification, the gene frequency of the second subline of Zmu?1:DHP inbred strain was 86. 7%,higher than Zmu?1:DHP outbred strain (6. 7%) and Zmu?2:DHP inbred strain (66. 7%). The average number of loci of Zmu?1:DHP inbred strain was 1. 13,lower than that of Zmu?1:DHP outbred strain (2. 47%) and Zmu?2:DHP inbred strain (1. 33%). The genotypic frequency of Zmu?1:DHP in?bred strain was also higher than that of the other strains. The gene types of Zmu?1:DHP inbred strain were included in the genes of Zmu?1:DHP outbred strain, but Zmu?1:DHP inbred strain was short of 2 characteristic genes. The gene homozy?gous rates of 8 sublines of Zmu?1:DHP inbred strain were different with each other,among them, those of the 2nd and 8th sublines were higher than others. Conclusions There are both homozygosity and specificity in the Zum?1:DHP inbred strain and Zum?1:DHP outbred strain. The second Zum?1:DHP subline becomes a new inbred strain guinea pig. It is es?sential that the subline with the characteristic property is screened from these sublines. The guinea pigs of black Zmu?2:DHP inbred strain carrying microsatellite markers not present in the white strains, may carry optimal genes related with hair color properties.关键词
