RAPD分析中遗传距离计算方法的比较

COMPARISONS OF CALCULATION METHODS FOR GENETIC DISTANCE IN RAPD ANALYSIS

为了更有效地应用ＲＡＰＤ分析这一手段研究种群遗传变异，以广州市力康鸡场７个蛋鸡品系为材料，根据ＲＡＰＤ测定的结果，采用Ｎｅｉ、Ｒｏｇｅｒｓｔ和Ｈｅｄｒｉｃｋ的遗传距离公式计算上述７个品系彼此间的亲缘关系，同时提出新的遗传距离计算公式。结论认为Ｒｏｇｅｒｓ的公式较适用于ＲＡＰＤ数据的分析，文中提出的公式跟其他距离公式存在显著相关，但有待进一步验证。

n order to study population genetic variations with RAPD analysis more availabel, the genetic distances among 7 layer lines in Guangzhou Leghorn Company Ltd wer lculated with Nei's equation, Rogers equation , Hedrick's equation and the equation developed by the authors based on RAPD analysis for 7 lines. It was concluded that Rogers genetic distance was more suitable to RAPD analysis data and that the authors genetic distance was correlated with the other genetic distances singificantly, but had to be tested further.
