Activators are more common than repressors in eukaryotes.

Explanation:

Eukaryotic transcription is regulated by repressor and activator proteins.

Linked reported genes decrease due to mutation of activator-binding proteins, instead of mutation of a repressor binding site which leads to an increase of the reporter gene.
