Internal rearrangement in the ry gene of the P{PZ} element.
lethal - all die before end of larval stage (with Df(2L)tkv2)
lethal - all die during embryonic stage | recessive
some die during embryonic stage | recessive
some die during larval stage (with Df(2L)tkv2)
embryonic/first instar larval cuticle
embryonic head
ventral denticle belt
Hemizygotes with Df(2L)tkv2 die at the first larval stage. Most homozygous embryos do not have any strong cuticle phenotype except for head defects, although some have Filzkorper defects and show lateral extension of the ventral denticle belt.
