Thalassemias are inherited disorders—that is, they're passed from parents to children through genes. People who inherit faulty hemoglobin genes from one parent but normal genes from the other are called carriers. Carriers often have no signs of illness other than mild anemia. However, they can pass the faulty genes on to their children. From the National Heart, Lung, & Blood Institute
THE BODY PERCENTAGE: the body is broken up into percentages of surface area taken up by each part for both ADULT FRONT/BACK and CHILD. Also, just notice how differently proportioned the child is comparing his/her percentages to the identical ones on the adult. This is mainly used for judging burns' severity when covering areas.
