Heterozygous larvae show no significant defects in dendrite morphology of ddaC neurons.
Heterozygous males do not have ectopic sex combs on the second or third legs.
ddaC clones mutant for hpoMGH4 exhibit simplified dendritic trees in third instar larvae, but show more extensive dendritic arborisations in earlier larval stages (second to early third instar), consistent with the involvement of hpo in the maintenance of dendrites. In hpoMGH4 mutant clones at earlier developmental stages, dendritic branches are often found to overlap.
hpoMGH4/+ heterozygotes exhibit wild-type dendritic tiling, with wild-type levels of dendritic crossing points per υm[2].

hpoMGH4 allows recovery of Df(1)su(s)R194/+ clones in the adult eye in animals with mosaic eyes containing two genotypes of cells with respect to RpL36; cells which are Df(1)su(s)R194/+ and cells in which the haplo-insufficiency of Df(1)su(s)R194/+ for RpL36 has been rescued by RpL36+t4 (in a wild-type background the Df(1)su(s)R194/+ clones are eliminated by cell competition and are not seen in the adult eye in these animals). hpoMGH4 does not prevent loss of Df(1)su(s)R194/+ clones in the wing disc.
Transheterozygotes for trc1/hpoMGH4 exhibit obvious iso-neuronal as well as hetero-neuronal tiling defects, including a significant increase in dendritic crossing-points compared to single mutants.
Transheterozygotes for trc2/hpoMGH4 exhibit obvious iso-neuronal as well as hetero-neuronal tiling defects, including a significant increase in dendritic crossing-points compared to single mutants.
Transheterozygotes for fry1/hpoMGH4 exhibit obvious iso-neuronal as well as hetero-neuronal tiling defects, including a significant increase in dendritic crossing-points compared to single mutants.
Transheterozygotes for wtsx1/hpoMGH4 display simplified dendrites similar to wtsx1 mutants.
Overexpression of trcScer\UAS.T:Zzzz\FLAG, under the control of Scer\GAL4elav-C155 in hpoMGH4 MARCM clones partially suppresses the dendritic tiling defects in class IV neurons.
Overexpression of wtsScer\UAS.L.T:Hsap\MYC, under the control of Scer\GAL4elav-C155 in hpoMGH4 MARCM clones does not suppress the dendritic tiling defects in class IV neurons.
