遗传学

Non-invasive sampling is a useful tool for genetic analysis of endangered species,but it is often inapplicable due to the low quality and quantity of DNA obtained.In order to explore a method for extracting DNA from specimen of bird,we tried to extract DNA from dried skin of birds.We extracted total DNA of the koklass specimens successfully.

20世纪80年代以来，由于PCR技术的广泛应用，已经能对极少量遗传物质进行检测，由此产生了一类新的取样方法——非损伤性取样[1]，即在不伤害或触及动物的前提下收集脱落的毛发、粪便、口腔脱落细胞、陈旧皮张等作为分析样品，进行遗传学分析。

The present study demonstrates that the utility of morphometric characters for defining stocks of kuruma shrimp is available,but further verification of the stockstructure(e.g.,genetic evidence)is essential.

本研究利用外部形态已成功之判别斑节虾之系群结构，但更进一步之验证如遗传学证据是必须的。

Methods Blood samples of 300 unrelated individuals from Chengdu, Bangkok and Maint were taken and analyzed with single PCR, polyacrylamide gel electrophoresis and silver staining. Results In the three loci, 9, 6, and 8 alleles and 32, 14, and 22 genotypes were found respectively.
