WALLACE（1966 a）在最近的一篇论文中分析了果蝇（Drosophilamehogaster）某些群体中I隐性致死基因的等位性。他特别关注的是在不同距离的采集点从自然种群中采集的致死基因的等位率。华莱士认为，相隔一定距离的两组致死基因之间的等位性可能与从种群中同一点采集但相隔一定时间间隔的两组致死基因之间的等位性有关。关于后一种关系，WALLACE进一步阐明等位率iTt和第一组和第二组致死样本之间的时间间隔t（以世代为单位）具有以下函数关系：
N a recent paper WALLACE (1966a) presented an analysis of the allelism of I recessive lethal genes in certain population of Drosophila mehogaster. His specific concern was the allelism rates of lethals taken from a natural population at collection sites of varying distances apart. WALLACE argues that the allelism between two sets of lethals from a given distance apart can be related to the allelism of two sets of lethals taken from the same point in the population but separated by a given interval in time. In connection with this latter relationship WALLACE further conjectures that the allelism rate iTt and the time interval t (in generation units) between the sampling of the first and second sets of lethals have the following functional relationship:
