amorphic allele - genetic evidence
abnormal locomotor behavior
lethal | recessive
partially lethal
uncoordinated (with DrMio)
visible
eye
macrochaeta
Heterozygotes with Dr1 have reduced viability, deranged bristles, uncoordination and small eyes. Heterozygotes with Dr1 revertant alleles are embryonic lethal.
