Figure 3.—

Examples of ovo-B reporter expression in wild-type and sex-transformed flies. The sex chromosome karyotype and differentiation phenotype are shown at the top and the reporter genotype is shown at the left. (A–D) Heterozygous for ovo^ΔapΔ4. (E–H) Heterozygous for ovo^ΔapΔ5. (I–L) Heterozygous for ovo^ΔapΔ6. (M–P) Heterozygous for ovo^ΔapΔ8. (A, E, I, and M) Wild-type females. (B, F, J, and N) Wild-type males. (C, G, K, and O) Males transformed into females with tra^Hsp83.PS. (D, H, L, and P) Females transformed into males due to absence of tra-2 [tra-2^B/Df(2R)Trix].
