Figure 1.
Phenotypic distribution of the sucrose response scores of the workers (A) and males (B) used for the quantification of the degree of genetic determination. The differences between worker groups suggest some dominance effects because the high backcross (HBC) is similar to the high pollen-hoarding strain, and low backcross (LBC) is similar to the low strain. The male data fit a general additive model. (A) () Low (n = 96), (
) LBC (n = 258), (
) HBC (n = 265), (□) high (n = 93). (B) (
) Low (n = 81), (
) hybrid (n = 158), (□) high (n = 34).
