Does this say that the gene is actually in two parts and each part is on a different chromosome but that if either part is present the gene manifests?

I read it to say that the gene is required and is either on C3 or C4. If a pair of mis-matched flies breed it's possible that the gene will not be on either chromosome in the offspring so those offspring will be sterile.
