Lethality of cdc7 flies is rescued by expression of Cdc7
Male cdc7G0148 flies carrying the Cdc7 genomic rescue construct on the second chromosome or male FM7c flies without the genomic rescue construct were crossed with female cdc7G0148/FM7c flies, and the surviving adult progeny was scored for presence of the FM7c balancer chromosome using the visible Bar eye marker. The percentage of flies corresponding to each genotype and the total number of scored progeny for each cross are indicated.
