Abl 1Q regulates the WRC at the midline. a Midline crossing overs in Abl mutants expressing Abl transgenes with 1407-Gal4, with gain or loss of Abi, or gain of trio. b Midline crossing overs in Abl mutants expressing Abl transgenes with 1407-Gal4, with heterozygous loss of Sra-1. Confidence intervals given are for penetrance of the phenotype. All counts are from 3 or more sets of embryo collections, with ~ 30 embryos per set; the n-value represents embryo count. Confidence intervals given are for penetrance of the phenotype. The direction of crosses is reversed between a and b due to a balancer-induced maternal effect
