TÌM 10 LỖI SAI GIÚP EM VỚI Ạ - MỌI NG GIẢI THIK THÌ CÀNG TỐT EM CẢM ƠN Why do some people back on when faced with a threat, while others stand up to it? When giving a difficult task, why do some people see it through while others give up? It all comes down to personalities. But where does that come from? Some scientists believe that most of traits are inherited. The others take the opposite view: personality, they say, is formed by our environment and parents do not pass it on in their children. The truth is probably anywhere in between. Some traits are clearly determined by your environment: However your genetic background, if you grow up in Sweden, you'll probably speak Swedish. On the other hand, when it comes to traits like the colour of your eyes or your blood type, it is clear that genetics alone accounts for them. There are also traits which are partly inherited but partly shaped by environment: your weight, and even your height and skin colour, are examples. Of course, genetics and the environment together are not the total picture. Your free will - your ability to take decisions - is also a factor in shaping your identity, but how big a factor? You'll have to make your own mind up for that!
