Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
Embryos derived from homozygous fs(1)M31901 females fail to develop structures posterior to the seventh abdominal segment as well as anterior-most structures, including the head skeleton. The posterior defect is significantly suppressed if the female is also carrying one copy of Dsor1Su1; an eighth abdominal segment is formed. This suppression is significantly reduced if the females are also carrying one copy of rl9.
