Heterozygotes have reduced viability.
Su(z)4[+]/Su(z)41 is an enhancer of adult metathoracic segment phenotype of brm[+]/brm2, trxE2
Su(z)4[+]/Su(z)41 is an enhancer of adult metathoracic segment phenotype of ash117, trxB11/trx[+]
Su(z)41, trxB11 has adult metathoracic segment phenotype
Su(z)4[+]/Su(z)41, trxB11 has adult metathoracic segment phenotype
Double heterozygotes with trxB11 show T3 to T2 transformations.
