The birthmarks are the marks or skin lesion formed before birth. They are not hereditary. The cause of birthmarks is not known. They can appear on any part of the skin. It is believed that they are made up of large number of blood vessels. These birthmarks are nothing to do with blood groups as these are not inherited. To find out your blood group visit a laboratory. To check the compatibility of your blood group with your parents, get DNA test of your parents and yourself.
