Detailed Description
Statement
Reference

Hsc70-4195/+ heterozygotes exhibit a wild-type number of sex combs, with 2 legs exhibiting sex combs.

Heterozygotes are phenotypically wild type.

The dominant phenotype of Hsc70-4195 is enhanced at 18oC compared to 25oC.

Statement
Reference

Pc4/Hsc70-4195 mutant flies exhibit a higher than wild-type average number of legs with sex combs, with a statistically significant average of 2.4 legs with sex combs, compared to 2.0 in wild-type.

ph-p409/Hsc70-4195 mutant flies exhibit a higher than wild-type average number of legs with sex combs, with a statistically significant average of 4.8 legs with sex combs, compared to 2.7 in ph-p409/+ heterozygotes.

ph-p2/Hsc70-4195 mutant flies exhibit a higher than wild-type average number of legs with sex combs, with a statistically significant average of 4.0 legs with sex combs, compared to 2.6 in ph-p2/+ heterozygotes.

In transheterozygous combination with EcR alleles, wings are frequently blistered and legs are often malformed.

Hsc70-4195 in combination with Df(3R)kar-D1 produces an eye phenotype.

The synergistic effect of Hsc70-4195 on N pathway mutants is suppressed by removing a copy of H.
