C284Y
Heterozygotes are phenotypically wild type.
EcRC284Y, Hsc70-4195/Hsc70-4[+] has visible | dominant phenotype
EcRC284Y/EcR[+], Hsc70-4195 has visible | dominant phenotype
EcRC284Y, Hsc70-4195/Hsc70-4[+] has wing phenotype
EcRC284Y, Hsc70-4195/Hsc70-4[+] has leg phenotype
EcRC284Y/EcR[+], Hsc70-4195 has wing phenotype
EcRC284Y/EcR[+], Hsc70-4195 has leg phenotype
In transheterozygous combination with Hsc70-4195, wings are frequently blistered and legs are occasionally malformed. This enhancement is completely suppressed by P{Hsc70-4.14}.
