Question

these genes had to be ______ farther apart on the chromosome. slathered welded positioned flicked

Explanation:

"Positioned" means placed or located. In the context of genes on a chromosome, it makes sense to say they are positioned at certain distances from each other. "Slathered" means spread thickly, "welded" is for joining materials like metal, and "flicked" means a quick light touch or movement, none of which fit the context.

Answer:

C. positioned
