Genetic Interactions
Statement
Reference

5+/-2% of KrIf-1/+ flies born to urd2/+ mothers have outgrowths with ectopic vibrissae protruding from the ventral region of the eye, compared to less than 0.1% of KrIf-1/+ flies born to isogenised wild-type mothers.

Mutant weakly suppresses the CycEJP rough eye phenotype.

The lethality caused by sevS11.T:Hsap\MYC in combination with Ras85DV12.sev is not suppressed by urd2.

Suppresses the extra sex comb phenotype of Pc21, AntpScx/+. Causes between 50% and 100% suppression of the Pc4/+ extra sex combs phenotype.
