非洲生物菌属物种命名的遗传基础很少受到关注。用淀粉凝胶电泳法对来自肯尼亚的白背飞虱、苏丹白背飞虱和白背飞虱的种群进行了检测。用赖特的F-统计量对苏丹白背飞虱和白背飞虱的种群结构进行的分析表明，这两个物种在随机交配下都表现出与预期的显著背离。白背飞虱种群近亲交配的证据最少，苏丹白僵菌种群介于白背飞虱和之前报道的白背飞虱近亲交配水平之间。白背飞虱和苏丹白背飞虱的同位居群在遗传上是不同的。白背飞虱和苏丹白僵菌的同位居群也显示出独立基因库的证据，尽管证据不像白背飞虱和苏丹白僵菌那样确凿。我们考虑了未能找到苏丹假单胞菌和白背单胞菌之间明显差异的可能原因。(C)2000年伦敦林尼安协会。
The genetic basis for species designations for African species of Biomphalaria has received Little attention. Populations of B. choanomphala, B. sudanica and B. pfeifferi from Kenya were examined using starch gel electrophoresis. Analysis of population structure as measured using Wright's F-statistics for B. sudanica and B. choanomphala revealed that both species show substantial departures from expectations under random mating. Populations of B. choanomphala show the least evidence of inbreeding, and populations of B, sudanica are intermediate between B. choanomphala and previously reported levels of inbreeding for B. pfeifferi. Syntopic populations of B. Pfeifferi and B. sudanica were genetically distinct. Syntopic populations of B. choanomphala and B. sudanica also showed evidence of separate gene pools, although the evidence is not as conclusive as for B. pfeifferi and B. sudanica. Possible explanations for the failure to find clear differences between B. sudanica and B. choanomphala are considered. (C) 2000 The Linnean Society of London.
