An Hsp70 promoter drives expression of a Mmus\Ovol2-A cDNA.
Mmus\Ovol2A.hs is a suppressor of female sterile | dominant phenotype of ovoD2
The fraction of ovoD2/+ females that produce eggs is increased if the females express Mmus\Zfp339A.hs using a 1 hour heat shock at 37oC; 16-68% of the heat shocked females produce eggs, compared to 4% of control ovoD2/+ females. However, almost all the eggs laid by the ovoD2/+ females carrying Mmus\Zfp339A.hs fail to hatch.
