and nurture. Identical twins and mice are a good example of this. Biologists have questioned how identical twins that have the same DNA can end up with different traits. For example one twin could develop bipolar disorder and the other twin is uneffected. So how does this happen when they have the same DNA? The answer is epigenetics.
