hypomorphic allele - genetic evidence
lethal - all die before end of P-stage | recessive
some die during P-stage | recessive
chromosome | larval stage
chromosome | larval stage (with Df(3R)Exel6167)
Brains from larvae either homozygous or hemizygous (over Df(3R)Exel6167) for timeoutf05903 consistently exhibited a substantial increase in the number of metaphases with chromosome aberrations compared to controls.
