If you are comparing the total gene expression of a black panther during its early development and later adult life and have labeled the cDNA you obtained from its early development stages with a green fluorophore and the cDNA you obtained from its adult life stages with a red fluorophore, what color would you expect to see on your DNA microarray for genes that are equally expressed in both the early development and adult life stages?
A) green
B) red
C) yellow
D) brown
E) magenta

The cDNA for early development is labeled with green fluorophore and the cDNA for adult life stages is labeled with red fluorophore. Therefore, if a gene is equally expressed in both stages, the microarray will show both green and red signals, which will appear as yellow due to mixing of the two colors.
