abnormal size | larval stage | somatic clone
decreased occurrence of cell division | larval stage
lethal - all die before end of larval stage | recessive
some die during larval stage | recessive
imaginal disc
wing disc | larval stage | somatic clone
Mutants exhibit visible disc abnormalities: very small or no discs. Clones induced in wild type discs are abnormal: mutation affects cell proliferation so the clone size is small.
