Shape: The shape of parents' eyes has obvious influence on 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, people with single eyelids and double eyelids get married, and the children are likely to have double eyelids. Therefore, some children are born with single eyelids, and when they grow up, they will "make up" their double eyelids like their fathers. According to statistics, the proportion of infants' double eyelids is only 20%, middle school students are 40%, and college students are about 50%. But if both parents have single eyelids, the average child will also have single eyelids.

Eye color: In terms of eye color, dark colors such as black are dominant compared with light colors. In other words, if you envy blue eyes, choose someone with blue eyes as your lover, but because you have black eyes, your child 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.

2. Nose

Generally speaking, people with big, tall noses and wide nostrils are dominant. If one of the parents has a straight nose, it is likely to be passed on to the child. In addition, the inheritance of the nose will continue into adulthood, that is to say, people with short noses when they are young may become tall noses when they grow up.

3. Life span

Life span has a genetic basis. We can see that some families live long, but there are also short-lived families. The length of life has a tendency of family gathering. 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 death time of twins aged 60-75 is 4 years, and the average death time of female twins is only 2 years. However, life expectancy will also be affected by environmental factors, such as eating habits, living environment, working environment, etc. These factors will also affect people's life expectancy to varying degrees.

4. Height

Research shows that 70% of people's height depends on heredity, and the influence of acquired factors only accounts for 30%. Generally speaking, if parents are tall, the probability of children being tall is 3, the probability of being short is 1, and the probability of being short is just the opposite. If one parent is taller and the other is lower, it depends on other factors.

5. Fat and thin

People's figure has certain heredity. For example, some of us eat the same food and do the same amount of exercise, but some people are in normal shape, while others are fat or thin. People think that different people have different metabolic rates. Generally, people with low metabolic rate tend to get fat, which is determined by the genetic factors of body shape. If parents are easy to gain weight, children are also easy to gain weight. Therefore, such children should pay attention to balanced nutrition after birth and don't eat too much. If one of the parents is obese, the probability of the child being obese is 30%. If both parents are obese, the chances of children getting fat are 50%-60%. In addition, there are also some sayings that mothers play a greater role in children's body shape, that is to say, children are more like mothers regardless of gender.

6. Skin color

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, parents with dark skin will never have children with white skin; If one parent is black and the other is white, then after "averaging" in the embryo, a neutral skin color that is neither black nor white will be formed for the child. 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 dark skin, and her child was born with dark skin.

7. Ears

The shape of the ear is hereditary, the big ear is dominant and the small ear is recessive. As long as one parent has big ears, then the child is likely to have a pair of big ears.

8. Chin

It is definitely dominant inheritance. Either parent has a prominent big chin, and nine times out of ten children will grow into similar chins. This feature is very obvious.

9. Sound

Children's voices are usually very close to their parents, and their similarity will be worse than their looks and figure. If the father smiles heartily and the mother has a loud voice, it is hard to imagine that the child will whisper. Usually, a son's voice is very close to his father's, while a daughter's voice is very similar to his mother's.

The size, volume and quality of sound are not only related to the larynx, but also determined by the size of the nose, the size of the mouth, the length of the tongue, the bones of the face and other factors. Moreover, these aspects are inherited from parents' genes, 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 voice through pronunciation training the day after tomorrow. In this way, some people with poor voice conditions can make sweet and mellow dreams through scientific and hard practice.

10. Intelligence

Although intelligence is not entirely determined by genetic factors, it has a certain relationship with heredity. Human intelligence depends on genetic and environmental factors. 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 average level of children. For those with mental defects, 59% of their children have mental defects 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 similar to their fathers in handling and communication skills, while others are similar to their mothers in personality and temper.

In addition, children's intelligence has a great relationship with the environment, and the actual performance of intelligence is greatly influenced by the day after tomorrow, so we advocate early education. 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's intellectual development to be good, 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, which will make your child's intellectual development good.

1 1. Parents' talent

Whether it is a father or a mother, some talents may be passed on to children, so that children have high potential in some aspects. Therefore, under the influence of the surrounding environment, if parents develop a certain talent properly, they can make their children develop better in this respect.
