Homozygous germline clones display maternal effect lethality. Embryos derived from heterozygous mothers exhibit a range of phenotypes from extreme to wild type.
Progeny produced from homozygous female germ-line clones are more nearly normal in appearance than those from fliI14 females.
Lefevre.
Maternal germline clonal analysis demonstrates there is a maternal effect lethal phenotype, gastrulation defects.
