What is Mutations? Mutations are when there is change in the genetic information (DNA) in the gene.

What causes Mutations? Mutagens are what cause Mutations. Mutagens such as mercury, cigarette smoke, x-rays and UV radiation, and some viruses cause mutations.

Positive Mutation is when a gene mutation benefits the individual. An example of this is when a seven year old girl had lucemia and a scientist injected her with with the HIV virus and it turned out to save her life and kill all the lucemia in the girl.

Negative Mutation is when the gene mutation harms the individual. An example of this is when some poeple are born with curved red blood cells rather than disced red blood cells.

Neutral Mutation is when the gene mutation doesn't affect the individual. An example of this if you have naturally curly or straight hair.
