True case: My grandmother lived to 1 18 years old and died. My mother 104, as healthy as ever. My sister is almost 80, and she is 74 years old. Three generations are so healthy and long-lived, no wonder Huang Zifan, a "longevity family" in Guidong County, Chenzhou City, was praised and envied by local people. What is the "longevity book" among them?

Scientific explanation: 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.

2. Height

Real case: Yao Ming's son is 2.4m long?

Yao Ming's wife, Ye Li, was happy, and the busybody discussed that the children born of two "masters" must be little giants. In fact, Yaoye's son may not stand out from the crowd, and the genetic factor of height accounts for 70%. It is common for children to "betray" their parents.

Scientific explanation: 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.

Step 3 be fat and thin

Real case: What kind of obesity do you belong to?

If you want to know your obesity type, it's actually very simple. Just do the following test to see which type you answer "Yes" more times, then you will sit in that type and refer to that type of weight loss points. If you answer "yes" to both types as many times, then you are a collection of both types, and you should refer to both types of weight loss points at the same time.

Scientific explanation: people's body shape 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.

4. Skin color

Real case: American doctors promote "customized babies" by randomly choosing gender and skin color.

Jeff, a 54-year-old famous fertility expert in the United States? Dr Steinberg recently announced that his fertility clinic will launch an incredible "customized baby" business within six months-parents will be able to "customize" a "perfect baby" they want, and choose the baby's sex, hair, eyes and even skin color at will, just like customizing an assembled computer!

Scientific explanation: skin color is often impartial in heredity, 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.

5. Eyes

Real case: Leshan century-old family suffers from a rare genetic disease cataract, which was passed down from men to women.

There are men in a family who have suffered from cataract with hearing loss since they were ten years old, and nine generations have been sick so far. At present, medicine can be traced back to hundreds of members of his family for six generations, and 23 people have cataracts.

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 and choose a person with blue eyes as your lover, but because you have black eyes, the child born will not be blue eyes.

Eyelashes: Long eyelashes are also dominant. As long as one parent's eyelashes are long and easy to use, recommend effective exfoliating products. How to eliminate dark circles, the best eye cream, which brand is good for sun protection, and which kind of uniform skin color is better, and it is very likely that children will inherit long eyelashes.

6. Nose

Real case: how to make a beautiful nose?

The nose is located in the middle of the face, towering and prominent, which plays a very important role in the outline and image of the whole face. Because appearance represents a person's education, wisdom and personality to a certain extent or at least on the surface, the nose plays an extremely important role in expressing the whole person's personality.

Scientific explanation: Generally speaking, people with big noses, high 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.

7. Will ears last longer?

The ancients believed that the kidney began with understanding the ears, so the big ears were a sign of kidney qi and health, and the kidney qi was sufficient to live a long life, so it is very important to protect the kidney if you want to live a long and healthy life.

Scientific explanation: 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

Real case: The smaller the female chin, the more attractive it is.

The research result from Nebraska State University was recently published in an American magazine. The researchers also found that the smaller a woman's chin is, the more attractive she is. Moreover, the smaller the nose, the wider the eye distance and the smaller the mouth width, the more popular women are.

Scientific explanation: it is absolutely 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. Real case of sound: The left brain can recognize sounds that are important to itself.

Why can people hear the voices of lovers or children in a noisy crowd? A research team recently found that this is because people's left brain auditory area can distinguish sounds that are important to them.

Scientific explanation: children's voices are usually very close to their parents, and the 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

Real case: A baby's IQ depends on a special gene.

The latest research shows that the IQ of a baby does not depend entirely on breastfeeding, but whether the baby carries special genes. Studies have also shown that only one in ten babies carries this gene.

Scientific explanation: although intelligence is not completely 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, parental talent

True case: Everyone is born with a "gift" for music.

Researchers from Stanford University in the United States and McGill University in Canada recently published an article in Neuron magazine, saying that music, like language, is one of the innate cognitive abilities of human beings, and people who know nothing about music are also born with "musical cells".

Scientific explanation: Whether it is a father or a mother, some talents may be passed on to children, which makes 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.
