Transfection with more than one Plasmid

[ybbobck]

If u transfect a mammalian cell line like 293 t with more than one plasmid , for instance one plasmid encodes for EGFP and the other encodes for E47, what are the chances that the 293 t cells take up ony one of the plasmid and not both.
If I vary the ratio of these 2 input plasmids..is there any chance that the cells take up just one plasmid...?
