Null embryos from homozygous female germlines differentiate poorly but have slightly more cuticle than Raf null embryos. Embryos from homozygous germlines that receive a paternal wild type Ras85D differentiate some structures posterior to A7, in some cases including posterior spiracles. A number of segmental fusions occur.
Homozygous lethal. Df(3R)ΔC40b/Ras85D05703 and Df(3R)ΔC40b/Ras85De1B transheterozygotes are lethal.
