    In combination with other aberrations

    Suppresses the position effect variegation of ry seen in In(3R)ryps11136.

    NOT in combination with other aberrations

    or the CNS phenotype. The construct shows that the midline cells are disorganised compared to wild type at stage 11 and at stage 13 are clustered near the ventral surface of the embryo leading to the collapse of the two lateral CNS hemiganglia and fusion of the longitudinal connectives. The presence of Ecol\lacZsim.7.8 construct fails to rescue lethality

    CNS defect.
