Abstract

Thirteen experimenital populationis of Drosophila willistoni were maintained in cages, in some of which the environments were relatively constant and in others varied. After 45 weeks, the populations were assayed by gel electrophoresis for polymorphisms at 22 protein loci. The average heterozygosity per individual and the average unmber of alleles per locus were higher in populations maintained in heterogeneous environments than in populations in more constant enviroments.

摘要

13个威氏果蝇实验种群饲养在笼子里，其中一些种群的环境相对恒定，另一些则有所变化。45周后，通过凝胶电泳分析这些种群在22个蛋白质位点的多态性。与处于更稳定环境中的种群相比，处于异质环境中的种群个体平均杂合度和每个位点的平均等位基因数更高。
