Genes Got A Gun

Steven Tyler of Aerosmith might not be a geneticist. However, what he phonetically sings '' Jeane' s got a gun'' is absolutely true. 30,000 human genes are shooting randomly all the time and they are responsible for all the united colors of Benetton traits; Tall, dark, curly, green eyed, short, asian, caucasian, healthy, blond, red head, you name it; all the phenotypes we see around.

However, we need to be carefull, a random shoot on an essential gene might cause a serious disease such as Cystic Fibrosis (CF).

Yes, the 'genes got a gun' and they should randomly. It is the geneticist work to identify the random targets.
