How else could growth occur on plates with both antibiotics with regard to ""successful"" transformation? (Hint: How else could you both genes ""get into"" bacterial cells?)

Only transformed cells will grow and the non-transformed cells will not grow. This will lead to conditioning of successful or unsuccessful transformation.

Explanation:

If both genes are included in the transformed cells and both genes show a resistance towards the antibiotics, the transformed cells will only grow on the plate in the presence of both the antibiotics.The non-transformed cells will not grow and the transformed cell will contain resistance against both the antibiotics.
