Expression under the control of Scer\GAL4¹⁴⁰⁷ results in loss of neuroblasts in the larval brain associated with decreased size of the remaining neuroblasts.

Expression under the control of Scer\GAL4¹⁴⁰⁷ results in a reduction in the average size of neuroblasts together with shorter neuroblast lineages (less daughter cells per neuroblast) in the larval brain compared to controls.

Adults expressing HP6^GD4434 under the control of Scer\GAL4^elav.PLu (in the presence of Dcr-2^Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.

Expression of HP6^GD4434 under the control of Scer\GAL4^G61 results in larvae with smaller salivary glands than normal. Polytene chromosomes show frequent telomere-telomere attachments. All the polytene chromosomes can participate in the telomere-telomere associations, although with different frequencies; the telomeres of the X chromosome and chromosome arm 3L appear to participate in the telomere attachments most often.

Expression under the control of Scer\GAL4^pnr-MD237 results in bristle morphology defects on the notum in 0% or 20-30% of the Scer\GAL4^pnr-MD237 expression domain, depending on the insertion line used.

Expression under the control of Scer\GAL4^pnr-MD237 results in the absence of 20-30%, 70-80% or 80-90% of the Scer\GAL4^pnr-MD237-expressing area of the notum, depending on the insertion line used.
