摘要
对基于SSR和AFLP的罗非鱼选育群体遗传变异开展对比研究,得到5个选育世代群体内多态位点指数SSR/AFLP比率平均为1.683 17,群体内Fst比率平均为1.249 87,群体内基因多样性比率平均为1.676 60。5个选育群体间遗传距离比率平均为3.972 02,遗传相似性比率平均为0.937 92。本研究结果可以为其它类似研究提供参考。
The genetic structure data of Nile tilapia from SSR assay were compared with that from AFLP. The ratio of polymorphic sites percentage from SSR to AFLP averaged 1.683 17, the average ratio of population specific Fst indices was 1.249 87, and the ratio of gene diversity in group averaged 1.676 60, respectively. The ratio of genetic distance among 5 populations of Nile tilapia from SSR to AFLP averaged 3.972 02, whereas the ratio of genetic identity averaged 0.937 92. The results about SSR and AFLP could provide reference for other similar studies in this field.
