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.
In eggs laid by mutant mothers, germ-band extension is delayed with respect to wild-type, and does not extend as far anteriorly. At later stages the germ-band fails to extend completely and instead invaginates into the anterior of the embryo. The majority of these embryos fail to complete embryogenesis. Less than 5% differentiate a cuticle.
Homozygous embryos hatch normally and first instar larvae are indistinguishable from their heterozygous siblings. The development of homozygotes is clearly retarded at the second larval instar stage and they die 5-6 days later without phenotypically entering the third larval instar stage.
Df(3L)10H, Lis-1unspecified has macrochaeta phenotype
Df(3L)10H, Lis-1unspecified has microchaeta & abdomen phenotype
The addition of Df(3L)10H (lacking Dhc64C) to Lis-1unspecified transheterozygotes results in defects in scutellar and abdominal bristle morphology.
