Most of our DNA is determined at the point of our conception. However, it is possible to change your DNA as a result of your environment or life style choices and pass these changes along to our offspring. These are called "germline mutations".
Germline mutations : is a permanent alteration in my DNA sequence that make up a gene.
A germline mutation is present in one of parents egg or sperm cells, also called germ cells. It is when one of these cells has the mutation the child that grows from the fertilized egg will have that mutation in his/her cells as well.
In contrast, other mutations might occur in other cells in our bodies called "body cells" these are not present in the egg or sperm cells and therefore not passed on to offspring.
Germline mutations can be caused from exposure to radiation (tanning beds); exposure to chemicals (smoking); infections (environmental consequences from where you live, the food and or water you consume).
