Phenotypes of the mutant alleles of S-Lap genes.

(A) Phenotypes of classical mutants (S-Lap1Δ7, S-Lap2MI14597, S-Lap3MB01319, S-Lap4MB11296, S-Lap5Δ14, S-Lap6MI06848) and RNAi lines (S-Lap7KK105511, S-Lap8KK106866) driven by bam-Gal4 testis-specific driver. (B) Diagrams show the average progeny yield of the S-Lap alleles in wild type (green), heterozygotes (blue) and in the transheterozygous (orange) combination. S-Lap1Δ7 allele shows a stronger reduction in progeny number among heterozygotes and gives no more than 40 offspring in average in genetic combinations with other S-Lap alleles. Error bars indicate mean +s.e.m., n = 15 **p<0.01, ***p<0.001, ****p<0.0001 (Student’s t-test).
