In addition to the health and gender of the child, the most common guess among expectant fathers and expectant mothers is who the child will look like in the future. Of course, this kind of guessing is much easier and more enjoyable than worrying about the child\’s health. Although for all parents in the world, as long as it is their own child, whether it is beautiful or not, smart or not, like mother or father, it will not affect their full love for their children.
There is such a story: a salesman traveled far away to support his family. One day, he suddenly met a fellow villager on the street who had not returned for many years. He learned that the fellow villager was about to return to his hometown. The salesman was overjoyed and asked his fellow villagers to bring something back to his son.
The fellow villager said: \”I don\’t know your child!\”
The salesman said proudly: \”You are very recognizable. The most beautiful one in our village is my son.\”

Unexpectedly, after the fellow villager returned, he walked around the village several times and felt that his son was the most beautiful, so he gave the things to his son.
Of course, this is just a joke, but it reflects the infinite love of parents all over the world for their children. Although it is not important to parents who a child will look like after birth, it is inevitable to speculate and fantasize. In this case, let me talk about the genetic rules of genes.
Eye Shape
The influence of parents’ eye shape on their children is obvious. For children, eye shape and eye size are inherited from their parents, and large eyes are dominantly inherited compared to small eyes. As long as one of the parents has big eyes, the chances of having a child with big eyes will be higher.
Single eyelids or double eyelids
Generally speaking, if a person with single eyelids marries a person with double eyelids, the child will most likely have double eyelids. Therefore, some children are born with single eyelids and become double eyelids as adults. According to statistics, only 20% of infants and young children have double eyelids, 40% of middle school students, and about 50% of college students. But if both parents have single eyelids, usually the child will also have single eyelids.
Eye color
In terms of eye color, dark colors such as black are dominantly inherited compared to light colors. In other words, if you envy blue eyes and choose a blue-eyed person as your lover, but because you have black eyes, the child you give birth to will most likely not have blue eyes.
Length of eyelashes
Long eyelashes are also dominantly inherited. As long as one of the parents has attractive long eyelashes, the possibility of the child inheriting long eyelashes is very high.
Nose
Generally speaking, people with large, tall noses and wide nostrils have dominant inheritance. If one of the parents has a straight nose bridge, there is a high possibility that this will be passed on to the child. In addition, the genetic inheritance of the nose will last until adulthood. In other words, a person with a short nose as a child may have a tall nose as an adult.
Lifespan
Lifespan has a genetic basis. We can see that some families have members who live long lives, but there are also short-lived families. Lifespan tends to agglomerate in families. If there is a precedent for longevity in your family, then your children are more likely to live a long life. The most telling is a study of identical twins. According to statistics, among twins who died between the ages of 60 and 75, the average time difference between male twins and female twins was 4 years, while the difference in death time between female twins was only 2 years. However, life span is also affected by environmental factors, such as eating habits, living environment, working environment, etc., which also affect human life span to varying degrees.
Height
Research shows that 70% of a person’s height depends on heredity, and acquired factors only account for 30%. Generally speaking, if the parents are tall, the chance of the child being tall is 30%, the chance of being short is 10%, and vice versa if the child is short; if one parent is taller and the other is shorter, it depends on other factors.
Fat and thin
Fat and thin body shapes are hereditary to a certain extent. Different people eat the same food and have the same amount of exercise, but some The human body has a normal shape, but some people are fat or thin. Research shows that different people have different metabolic rates, and people with lower metabolic rates are usually more likely to gain weight. This is determined by genetic factors in body shape. If the parents have a body shape that makes them prone to obesity, their children will tend to be obese. If one parent is obese, the child has a 30% chance of becoming obese. If both parents are obese, the chance of the child becoming obese is 50% to 60%.
Skin color
Skin color is often inherited impartially, leaving people with no choice. It always follows the natural law of \”multiply and average\”. For example, if parents have dark skin, the chance of them having a child with fair skin is very small; if one parent is dark and the other is fair, the child will have an intermediate skin tone. Therefore, children born to yellow people must have yellow skin color. If an African marries an Asian, the child will have dark skin.
Ears
The shape of ears is inherited, and big ears are dominantly inherited, while small ears are recessively inherited. Only one person from both parentsIf the child has big ears, then the child will most likely also have big ears.
The lower jaw
The lower jaw is definitely a dominant inheritance. If either parent has a protruding chin, the child will most likely grow up to have a similar chin. This characteristic is very obvious.
Voice
Children’s voices are usually very close to their parents, and they are even more similar than their appearance and shape. If the father has a hearty laugh and the mother has a loud voice, it is hard to imagine that the child will speak softly. Usually a son\’s voice is very close to his father\’s, and a daughter\’s voice is very similar to her mother\’s. The pitch, volume, and quality of the sound are not only related to the larynx, but are 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 all inherited from the genes of the parents, so it is not surprising that the voice is inherited. However, if the sound quality affected by the physiological and anatomical structure of the parents is not beautiful, most of it can be changed through acquired pronunciation training. Therefore, some people whose voice conditions are not superior will have voice changes through acquired pronunciation training. In this way, some people whose voice conditions are not superior can realize their dream of having a sweet and mellow voice through scientific and hard practice.
Intelligence
Although intelligence is not entirely determined by genetic factors, it has a certain relationship with heredity. Human intelligence depends on both genetic and environmental factors. It is generally believed that genetics plays a large role and environment determines the other 40%. Someone has long studied a group of children with IQs above 140 points, and found that these children have maintained excellent intelligence when they grow up. The average IQ of their children is 128 points, far exceeding the level of ordinary children. As for those with mental disabilities, 59% of their children have mental disabilities or mental retardation. According to scientists\’ assessment, in terms of genetics, if the mother is smart, most of her children will be smart, and if they are boys, they will be smarter. The reason for this is that human genes related to intelligence are mainly concentrated on the X chromosome. Women have two X chromosomes and men only have one, so the mother\’s intelligence occupies a more important position in heredity.
In the inheritance of intelligence, it includes not only IQ, but also emotional intelligence. The so-called emotional intelligence refers to a person\’s personality, temperament, ability to deal with things, communication skills, etc. For example, some children are like their father in terms of handling and communication skills, while in other aspects, such as personality and temperament, they are very similar to their mother. In addition, children\’s intelligence is also closely related to the environment, and the actual performance of intelligence is also greatly affected by the day after tomorrow.
Talent
Whether it is a father or a mother, talents in certain areas may be passed on to children, making the children have great potential in certain areas. high. Therefore, certain talents of parents, under the influence of the surrounding environment, if properly developed, can enable children to thrive in this world.There will be better development in this regard. Since ancient times, there have been many extremely talented families, such as the Bach, Mozart and Weber families, where many musicians have appeared in several generations. This phenomenon of family aggregation of intelligence just illustrates the role of innate and acquired factors in talent and talent.
Baldness
Baldness is only passed on to men. For example, if a father is bald, there is a 50% chance of passing it on to his son. Even the mother\’s father will pass on a 25% chance of being bald to his grandchildren.
Acne
This \”face problem\” that bothers boys and girls is actually related to heredity. Because if both parents have suffered from acne, the children\’s incidence will be 20 times higher than those without a family history.
Twins
Dizygotic twins are generally inherited from the maternal line, while monozygotic twins have nothing to do with genetics. If a woman herself is one of dizygotic twins, the probability of giving birth to twins is higher than if her husband is one of dizygotic twins, suggesting that the mother\’s genotype has a greater impact than the father\’s.
