Affects female fertility.

(Mazina et al., 1991)

Heterozygotes with br^2Bab-1, br⁵, br^2Bab-3 and br^npr-5 are completely lethal. Heterozygotes with br⁶. br^2Bab-2. br⁷. br⁸ and br^npr-6 have reduced viability and br wings. Heterozygotes with br¹ or br³ have normal viability and br wings. Heterozygotes with br^rbp-1, br^rbp-2, br^rbp-3, br^rbp-4 or br^rbp-5 have normal viability and reduced bristle number on the palpus.
