@Iceauror8, it's not really impossible more of rare. A "normal" human would have 46, XX/XY chromosomes. Non-disjunctions can create individuals with rare abnormalities such as, as said in my previous reply, 47, XXY / XYY / XXX. Even more rare are individuals with 48, XXXX, XXXY. Extremely rare are the ones with 49 chromosomes (5 sex chromosomes; 49, XXXXX / etc.).
