Re-integration of sequence using the attP site present in brkKO, resulting in a mutated brk gene (the 3R and GiM domains have been mutated) at the native locus (with in addition an attR site in the 5'UTR and a loxP site in the 3'UTR).
lethal
some die during embryonic stage
visible | somatic clone
ventral denticle belt
wing | somatic clone
Mutants show loss of ventral denticles.
Homozygous clones result in outgrowths in the wing.
