Russians and British. What's the difference between Americans' looks?

1, the British are serious and indifferent, on the contrary, Americans are "naturally familiar" with everyone.

2. Americans pursue an infectious smile. Almost everyone will wear braces to correct their teeth during adolescence, and they also pay great attention to maintenance. So it must be an Englishman who sees yellow and messy teeth.

3. British people generally have large foreheads, high baldness rate and early baldness.

The United States was originally inhabited by Indians. 13 Before the 8th century, Britain established13 British North American colony on the Atlantic coast of the United States. ? 1783 At the end of the War of Independence, Britain recognized the independence of 13 colonies. 1787, the constitution of the United States was passed, and a federal state was established.

The United States was originally a British colony, so most Americans are not much different from the British.

Factors affecting appearance

1, absolute inheritance

Skin color: people have no choice. It always follows the natural law of parents' "neutral" color. For example, parents with dark skin will never have children with white skin; If one side is white and the other side is black, most children will be given a "neutral" skin color that is neither white nor black after being "averaged" in the embryo, but there are also cases that are more biased to one side.

Jaw: it's a dominant inheritance, so you can't "discuss". "Image" makes you helpless. For example, even if either parent has a prominent chin, children often have similar chins without exception, which is somewhat bizarre.

Double eyelids: it is also an "absolute" inheritance. Interestingly, most of the father's double eyelids will be left to the children. Some children are born with a single eyelid, and when they grow up, they will "fill" the double eyelids like his father. In addition, big eyes, big earlobes, high nose and long eyelashes are the most characteristic inheritance that can be obtained from parents when the five senses are inherited.

2, more than half of the probability inheritance.

Obesity: Children will have a 53% chance of becoming obese. If one parent is obese, the probability of children being obese will drop to 40%. This shows that about half of being fat can be determined by human factors. Therefore, parents can make their posture symmetrical through reasonable diet and adequate exercise.

Baldness: the creator seems to favor women and let baldness be passed on only to men. For example, if the father is bald, the probability of passing it on to his son is 50%, and even the mother's father will leave his 25% probability of baldness to his grandchildren. This sexual genetic tendency of passing on men but not women makes men very helpless.

Acne: This facial disease that worries both boys and girls is actually related to heredity. Because if both parents have suffered from acne, the prevalence rate of children will be 20 times higher than that of children without family history.
