^*Indicates numbers that are statistically significant by the sign test. GD, gonadal dysgenesis; A, crosses using TP females; B, crosses using transgenic females.

^aTwo factors—the telomeric element (TP6) and the hobo transgene—segregated in the test crosses, giving rise to four genotypic classes in the F₂. The headings indicate which of these two factors were present in the females that were scored for GD.

^bThe four categories of data have been pooled into two categories to assess the effect of the transgene in the F₂ females that were scored for GD.

^cUnweighted average percentage GD ± SE.

^dNumber of vials in which the F₂ females carrying the transgene had a lower GD frequency than the females not carrying it.
