When the baby is still in the mother's belly, the father-to-be and the mother-to-be will always imagine who the baby will look like in the future. As the month gets bigger and bigger, many parents and moms are looking forward to the healthy growth of their babies.
In fact, the baby's IQ and appearance are very important for the child's future life. So which of these two aspects is more genetic?
Genetics of appearance
1. Eyes
If the husband and wife, one of them is a double eyelid, large eyes, then the child born later is double eyelids, the probability of large eyes will be greater, because the eyes including the color of the eyeball and eyelashes are dominantly inherited.
2. Nose
Like the eyes, the nose is a dominant gene. If there is a person on both sides of the husband and wife, the nose is very large, and it is high and straight, then the baby is likely to grow a tall and straight nose bridge in the future.
3. Ears
The shape of the ear is also very easy to inherit, if both parents have a person with large ears, which is commonly known as the wind ear, then the child is very likely to inherit such a pair of large ears.
4. Skin tone
Skin color genetics should be divided into boys and girls, if it is a boy, the skin color is mainly formed by the fusion of skin color genes between the two parents.
If it is a daughter, the skin color of the genetic father will be more likely, if the father's skin is whiter and more delicate, then the skin of the daughter born in the future will not be too dark.
The genetics of IQ
Although a person's IQ level has a certain hereditary nature, it will also be affected by the living environment, growing nutrition and later educational factors. Studies have shown that the influence of heredity on intelligence is only 50% to 60%, so acquired attention can also improve children's IQ to a certain extent.
If the mother is very smart, genetically speaking, then most of the future children are very smart, and if it is a boy, it is even smarter. Mainly because the genes related to human and intelligence are mainly concentrated on the X chromosome, everyone knows that women have two X chromosomes and males have only one, so the intelligence of both mothers in the husband and wife occupies a very important position in the genetics.
When giving birth to a boy, the combination of chromosomes is xy, and when a girl is born, the chromosome is xx, so when giving birth to a boy, the boy's IQ is all genetic mother's, if it is a girl who is born, then the girl's IQ is half of the influence of the father and the mother.
In addition to IQ and appearance, personality is also affected by genetics
Some experts have made corresponding explanations, and the biggest proportion of the impact on the formation of children's personality is the maternal mood. That is to say, when the expectant mother is pregnant, if she is not in a good mood, she often sulks. Then it will directly affect the personality genes of the fetal treasure. Although genetics have a great impact on the formation of the child's personality, the environment of the acquired life also has a great relationship with the formation of the child's personality, but it is still insufficient compared to the mood of the mother.-
That is to say, when the baby feels bad emotions in the mother's belly, it is likely to form an irritable, timid personality, and once this is finalized, it is difficult to correct the day after tomorrow.
If 60% to 70% of a person's personality has been formed in the womb, then when the mother is pregnant, if she is always angry and cannot control her emotions, most of the children born may also be a violent temper. Don't think that the baby is still small in the belly, can not feel the mother's emotional fluctuations, in fact, pregnant mothers in the excitement, anger, anxiety, happy time, the baby can be very clearly felt, but also will make a corresponding response, this is what many mothers say, if they are in a bad mood, the baby will have the behavior of kicking the stomach.
In addition to the maternal-fetal mood, the child's personality is affected by the acquired living environment accounted for 30%. As children continue to grow older, they will face more and more new things in the future, and they will also meet different people, and these external factors will change the child's personality. It's just that the proportion of personality changes because of the environment is very low, only about 30% to 40%.
Although genetics and maternal-fetal emotions have a significant impact on the formation of the baby's personality, we must know that in a person's life, if you encounter family changes or major events, it is also likely to change a person's personality.
The baby's appearance, IQ, and personality are more or less affected by genetics, but not all of them are immutable.
No matter how to guide the child to a positive aspect, and when the baby is still in the stomach, you should provide him with a good environment (including positive emotions), so that the baby can easily cope with various problems after birth. Who does your baby look like more? Is it also as smart as mom?
