Table 8. --Theoretical population and genotypic trends of female insects when native population of 2,000 Insects (3 autosomal genes BBDDEE 

 plus 1 sex-linked gene AA; female is heterogametic) is overflooded by 198,000 or 396,000 partially sterile insects (aabbddee and 

 a-bbddee) during parental, F. , F~ , ant ^ F3 generations. Matings between partially sterile insects are assumed to yield no offspring —
