1. Eye shape: Parents' eye shape has obvious influence on their children. For children, eye shape and eye size are inherited from parents, and big eyes are dominant over small eyes. As long as one parent has big eyes, it is more likely to give birth to a child with big eyes. Double eyelids: Generally speaking, if a person with single eyelids and double eyelids marries, the child is likely to have double eyelids. Some children are born with single eyelids and will "repair" their father's double eyelids when they grow up. According to statistics, the proportion of double eyelids in infants is only 20%, that in middle school students is 40%, and that in college students is about 50%. But if both parents have single eyelids, ordinary children will also have single eyelids. Eye color: In terms of eye color, dark colors such as black are dominant compared with light colors. That is to say, if you and I choose a person with blue eyes as my lover, but because you have black eyes, the child born will not have blue eyes. Eyelashes: Long eyelashes are also dominant. As long as one parent has touching long eyelashes, the child is likely to inherit long eyelashes. Generally speaking, people with big noses, high noses and wide nostrils are dominant. One of the parents has a straight nose, so it is likely to be passed on to the child. The heredity of the nose will last until adulthood, that is to say, people with short noses when they are young may become tall noses when they grow up. 3. Longevity has a genetic basis. We can see that some family members are long-lived, but there are also short-lived families. The length of life tends to gather with families. If there is a precedent of longevity in your family, then your child is likely to live a long life. The most convincing is the survey of identical twins. According to statistics, the average time difference between male twins and female twins at the age of 60-75 is 4 years. But life expectancy will also be affected by environmental factors, such as eating habits, living environment, working environment and so on. , but also affect people's life span to varying degrees. Height research shows that 70% of a person's height depends on heredity, and the influence of acquired factors only accounts for 30%. Generally speaking, if the parents are tall, the probability of their children being tall is 3, and the probability of being short is 1, and vice versa. If one parent is higher than the other, it depends on other factors. 5. The body shape of fat and thin people has certain heredity. For example, some of us eat the same food and do the same amount of exercise, but some of us have normal bodies and some are fat or thin. Studies have shown that different people have different metabolic rates, and people with lower metabolic rates are prone to gain weight. This is determined by the genetic factors of body shape. If parents' body type is easy to gain weight, children will tend to be overweight. Therefore, after such children are born, they should pay attention to balanced nutrition and not eat too much. If one parent is obese, the chance of the child becoming obese is 30%. If both parents are obese, the chances of children getting fat are 50%-60%. In addition, there are some sayings that mothers are. In other words, both men and women, children are more like mothers. 6. Skin color is often genetically impartial, leaving people with no choice. It always follows the natural law of "average after multiplication" and gives children the brand of "comprehensive color" of their parents. For example, a child with dark skin will never have white and tender skin; If one parent is black and the other is white, the child will be given a neutral skin color that is neither black nor white after the embryo is "averaged". Therefore, the child born to the yellow race must be the skin color of the yellow race. An African student found a China woman with a darker complexion, and the baby she gave birth to was really dark. 7. The shape of the ear is hereditary, and the big ear is dominant. Small ears are recessive inheritance. As long as one parent has big ears, then the child is likely to have a pair of big ears. 8. Chin is absolutely dominant. If either parent has a prominent chin, the child will grow into a similar chin nine times out of ten. This feature is very obvious. 9. Children's voices are usually very close to their parents, and their similarity will be worse than their appearance and appearance. If the father laughs, the mother is loud, and it is hard to imagine that the child will whisper. Usually the son's voice is very close to his father's, and the daughter's voice is very similar to his mother's. The level, volume and quality of sound are not only related to the larynx, but also determined by factors such as the size of the nose, the size of the mouth, the length of the tongue and the bones of the face. Moreover, these aspects are inherited from parents, so it is not surprising that sound is inherited. However, if the sound quality influenced by parents' physiological anatomical structure is not beautiful, most of it can be changed through acquired pronunciation training. Therefore, some people with poor voice conditions will change their voices through pronunciation training the day after tomorrow. Such people with poor voice conditions can also have a sweet and mellow voice through scientific and hard practice. 10. Although intelligence is not entirely determined by genetic factors, it is related to heredity. Human intelligence depends on heredity and environment. It is generally believed that heredity plays a great role, and the environment determines the other 40%. Some people have studied a group of children with IQ above 140 for a long time, and found that these children have maintained excellent intelligence since they grew up. The average IQ of their children is 128, far exceeding the level of ordinary children. Among their children, 59% have mental retardation or mental retardation. In the inheritance of intelligence, it includes not only IQ, but also EQ. The so-called emotional intelligence refers to people's personality, temper, ability to handle things, communication skills and so on. For example, some children are like their father in dealing with things and communication skills, while others are like their mother in personality and temper. In addition, children's intelligence has a great relationship with the environment. The actual performance of intelligence is greatly influenced by the day after tomorrow, so early education is advocated. From the fetus, the first peak of brain cell development appears in 10- 18 weeks, and the second peak appears in 3-6 months after the child is born. If you expect your child to develop well mentally, you should pay attention to nutrition intake during the first peak period, that is, during pregnancy, and pay attention to breastfeeding during the second peak period. Only in this way can children's intelligence develop well. 1 1. Parents' talents, whether they are fathers or mothers, may be passed on to children in some aspects, so that children have high potential in some aspects. Therefore, under the influence of the surrounding environment, if developed properly, children can develop better in this respect. Since ancient times, there have been many families with high intelligent structures. Such as Bach, Mozart and Weber, there are many generations of musicians. In addition, the son and grandson of Zu Chongzhi, a famous scientist in the Southern and Northern Dynasties, were both mechanical inventors and famous astronomers and mathematicians. This phenomenon of family gathering of intelligence just illustrates the role of innate and acquired factors in talent.
