Number of progeny scored

Frequency of exceptional progeny; see text for assay

Frequency of J21A presence in female progeny; see text for assay. The female parents in the seventh row were heterozygous for the parental chromosome (Nipped-B⁺) used to generate the Nipped-B⁴⁰⁷ and Nipped-B^292.1 mutations (Rollins et al. 1999).
