GlyP^3-13 homozygous adults do not show obvious morphological defects, despite a small but significant decrease in body mass only in males. GlyP^3-13/Df(2L)ED119 transheterozygous male and female adults also show a small but significant decrease in adult body mass.

GlyP^3-13 homozygous adult males show a significant decrease in climbing ability only under starved conditions, but do not show significant defects in flight ability, as compared to controls. GlyP^3-13/Df(2L)ED119 transheterozygous adult males do show significant changes in climbing ability, as compared to controls.

GlyP^3-13 homozygotes show significant mortality during the larval stages, which is not related to molting defects, as evidenced by the completion of molting from the late second to third instar. Body size is normal at 24h and 48h after larval hatching (i.e. late first instar and late second instar, respectively), but is significantly smaller than controls both at 72h after larval hatching (i.e. mid-third instar) and, although less severe, at pupariation; the are no changes in developmental time to pupariation; third instar larvae food consumption is comparable to controls.

Embryos laid by GlyP^3-13 mothers exhibit a delay in hatching and a slight decreased in hatching rate, as compared to controls.

Glyp^3-13 has increased mortality during development phenotype, enhanceable by Tps1^d2
