Early genetic manipulation of petunias included an attempt to engineer dark purple petals. To this end, extra copies of the gene that causes purple pigment was engineered to be produced in the petunia. However, to the surprise of many, the plants carrying the extra copies of the purple gene were completely white or only had patches of color. Molecular analysis revealed that the purple gene was reduced 50-fold in the engineered plants compared to wild type. Provide a possible explanation how this occurred. Also, provide a possible experiment that may overcome this setback
