摘要： The goal of the present study was to compare the different survival of Oxya chinensis exposed to chromium(VT) among allozyme genotypes to gain a better understanding of the relationship between the genetic variations and environmental disturbance. This study analyzed the occurrence of genotypes in O. chinensis population exposed to Cr(VI). O. chinensis samples were collected at Yuanping, Shanxi Province, China and used in acute toxicity tests. Specimens were assigned to Cr(VI) exposure (LD{sub}50: 291.0 mg/kg) for 24 h. The genetic composition of both dead and survived specimens was analyzed with horizontal starch gel electrophoresis in four enzymes (GPI, PGM, LDH, and ME). The results indicated that under Cr(VI) exposure, specimens with different genotypes had various mortalities at the four loci in laboratory conditions, and there was a genetic basis for tolerance in O. chinensis during acute exposure to Cr(VI).
