摘要
利用水平电泳方法对方蟹科方蟹亚科粗腿厚纹蟹 ,弓蟹亚科日本绒螯蟹、中华绒螯蟹、肉球近方蟹、绒螯近方蟹、平背蜞及斜纹蟹亚科齿突斜纹蟹进行遗传分析 ,计检测了 9种同工酶 ,1 2个位点。结果表明 ,七种蟹类的多态座位比例及平均杂合度分别为 :0 1 67和 0 0 0 3,0 2 50和 0 0 36,0 333和 0 0 62 ,0 2 50和 0 0 1 2 ,0 0 83和 0 0 0 2 ,0 0 83和 0 0 59,0 0 83和0 0 0 2。最小遗传距离为日本绒螯蟹和中华绒螯蟹之间的 0 0 1 1。由根井遗传距离可知弓蟹亚科与方蟹亚科的遗传关系较近 。
Horizontal starch gel electrophoresis was used to investigate the genetic relationship among seven Grapsidae species: Pachyrapsus crassipes (Grapsinae), Eriocheir japonica, E. sinensis, Hemigrapsus sanguineus, H. penicillatus, Gaetice depressus (Varuninae) and Plagusia dentipes (Plagusiinae). Twelve putative enzymk loci were examined. The average proportion of polymorphic loci and heterozygosity of the seven species were 0.167 and 0.003, 0.250 and 0.036, 0.333 and 0.062, 0.250 and 0.012, 0.083 and 0.002, 0.083 and 0.059, 0.083 and 0.002 respectively. The smallest Nei's genetic distance was 0.011, which was between Eriocheir japonica and E. sinensis. It is known that the Varuninae is near the Grapsinae and Plagusiinae is far from them from Nei's genetic distances.
