Can Human DNA Be Altered Naturally? There are no known examples of such types of alterations occurring in nature. Where T-DNA has been introduced spontaneously, it was with sequences stemming from A. tumefaciens in between. Allele swaps do occur, especially as a result of recombination during meiosis.
