How do scientists produce new genetic variations not found in nature? by a transforming rna b using gel electrophoresis. c using lasers to cut and paste dna. d causing mutations with chemicals or radiation?

Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.
