Abstract

Vertical polyacrylamide gel electrophoresis was used to separate enzyme proteins at 73 putative loci in natural house fly populations sampled in central Iowa. Thirty-nine of the loci were polymorphic (53%). The mean effective number of alleles per polymorphic locus was 1.93 and 1.47 alleles among 68 scored loci. Observed and expected heterozygosities at 34 house fly loci were 0.1628 and 0.1834, respectively. No statistically significant differentiation was detected among nine central Iowa fly populations in 1989 or among nine Iowa and three Minnesota populations in 1990.

摘要

采用垂直聚丙烯酰胺凝胶电泳法，对从爱荷华州中部采集的家蝇自然种群中73个假定基因座的酶蛋白进行分离。其中39个基因座具有多态性（占53%）。每个多态性基因座的平均有效等位基因数为1.93，在68个已计分的基因座中，平均等位基因数为1.47。在34个家蝇基因座上，观察到的杂合度和预期杂合度分别为0.1628和0.1834。1989年，在爱荷华州中部的9个家蝇种群之间，以及1990年在爱荷华州的9个种群和明尼苏达州的3个种群之间，均未检测到具有统计学意义的差异。
