amorphic allele - molecular evidence
Imprecise excision of P{lacW}DdG0269 resulting in complete removal of the Dd ORF.
partially lethal - majority die | embryonic stage | recessive
partially lethal - majority die | pupal stage | recessive
Ddex28 homozygotes show 52% lethality at the embryo stage, no significant lethality at the larval stage, and 97% lethality of remaining animals at pupal stages.
