FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Embryos show a germ cell migration defect and a significant reduction in the number of gonadal mesodermal cells.
In Ubxhs.PG embryos that are homozygous for ftzunspecified the C3 belt, cirri and mouth hooks are missing.
Parasegments 2, 4, 6, 8, 10, 12 and 14 are deleted.
ftzunspecified is partially rescued by ftzhb.PP
2 mutants are isolated.
