You perform comparative genomic hybridization. Instead of using cancer cells, you accidentally make both red and green DNA molecules from normal tissue. What will your ratio of green fluorescence to red fluorescence be?

1:1

Explanation:

Based on the information provided within the question it can be said that in this scenario the ration of green fluorescence to red fluorescence would be 1:1. This is because there is no mention in the question of deletions or duplications being detected, and cancer cells have no effect in this scenario, therefore the ratio will always be 1:1
