Contains ftz genomic DNA sequence from -75bp through to +2.5kb, under the control of the hb promoter.
Approximately 20% of ftzhb.PP homozygous adults lack external genitalia that derive from anlagen of segments A8 to A11.
ftzhb.PP is a suppressor of lethal | female phenotype of hryhb.PP
ftzhb.PP partially rescues ftzunspecified
ftzhb.PP partially rescues the pattern defects of mutant embryos deficient for ftz : the T1 'beard' is restored, as are various chitinised mouthpart structures.
