larval brain
Transheterozygotes are female sterile, exhibit no cuticular, testis or premeiotic defects but do exhibit a mutant brain phenotype. No defects in spermatogenesis so transheterozygous males are fertile.
Phenotype assayed in trans with a multiple mutant chromosome carrying mutations of polo, mgr, asp, stg and gnu.
