Mothers will argue with their children and their fathers about whether the child in their belly is male or female and who they look like, right?
What do you want your baby to look like? Eyes like you, nose like him? Figure like you, IQ like him?
But whose genes make everything about a child? Let's take a look at it together!
Height inheritance: half of the parents.
In addition to nutritional status, 70% of the initiative of a child's height is in the hands of the parents, and the genetics of the parents are the main factors that determine the height of the child, because 35% of the factors that determine the height come from the father and 35% from the mother. If both parents are not tall, it depends on the baby's 30% effort the day after tomorrow.
Intellectual Genetics: Mom.
Intelligence has a certain hereditary nature, and is also affected by acquired factors such as environment, nutrition, and education. According to scientists, genetics affect intelligence accounted for about 50%-60%, in terms of genetics, the mother is smart, most of the children born are smart, if it is a boy, it will be more intelligent. The reason is that human genes associated with intelligence are mainly concentrated on the X chromosome. Women have 2 X chromosomes and males have only 1, so the mother's intelligence occupies a more important place in heredity.
To prove this, let's first review the high school biology knowledge: how baby boys and girls came about.
Boys are XY, X (eggs) are from the mother, and Y (sperm) is from the father.
Girls are XX, X (eggs) are from the mother, and X (sperm) is from the father.
Therefore, giving birth to boys and girls is the fault of The husband, do not blame the mother's belly is not contentious.
Please note that boys are XY, so boys' IQs are all inherited from their mothers, and girls are XX, so girls' IQs are half influenced by their father and mother.
Because the IQ of girls is influenced by both father and mother, there will be a neutralizing effect, so the distribution of girls' IQ will show a natural distribution (normal distribution), that is, inverted bell shape, the most in the middle, and less on both sides.
Then because boys are completely affected by only one party, the distribution of boys' IQ will show a bias at two extremes. That is to say, there are more male geniuses, but at the same time, there are also many boys among the fools.
These tell us:
01. Judge whether a boy is smart or not, just look at his mother.
02. Then we use the probability to calculate:
The chance of having a boy = 1/2; the chance of having a girl = 1/2.
When giving birth to a boy, the mother's influence on the boy's IQ = 1.
When giving birth, the mother's influence on the girl's IQ = 1/2.
So if you:
01. It's the boy who thinks he's stupid, and you have to marry a smart girl. In this way, your child has a 75% chance of turning over, and life is still full of hope.
02. It's the girl who thinks she's stupid, because you have a 75% chance of flipping people's plates, so try to have a baby girl.
03. When you see a boy who is smart, the chance that his father is smart is 0% (it should be said that even if his father is smart, it has no effect on him), but the probability that his mother is smart is 100%.
Well, if you are thinking about marrying a very smart boy, you have to be careful of his mother, who may be a very calculating mother-in-law.
Personality Genetics: Dad.
Personality is the father's genetic large. Although the formation of personality has innate components, it is mainly acquired. Comparatively speaking, Dad's influence will be greater than Mom's. Among them, the role of father's love has a greater impact on the daughter. According to one psychologist, "Fathers play an important role in the formation of their daughters' self-esteem, sense of identity, and gentle personality." Some experts have suggested that fathers can teach their daughters many important lessons and experiences in life, making their daughters' personalities more colorful.
Physiognomy: Specific analysis of specific problems.
Skin color: Always follow the natural law of "multiplying and then averaging", leaving people with no choice. If the parents have darker skin, there will never be children with white and tender skin; if one side is white and the other is black, most of them will give their children a "neutral" skin color, and there are also cases that are more party-oriented.
Eye shape: The shape and size of a child's eyes are inherited from their parents, and the large eyes are dominantly inherited relative to the small eyes. If one of the parents has big eyes, the possibility of having a child with big eyes will be larger.
Double eyelids: Double eyelids are dominantly inherited, and babies with single eyelids and double eyelids are most likely double eyelids. But parents are single eyelids, and generally children are single eyelids.
Eyeball color: Dark colors such as black are dominantly inherited relative to light colors. That is to say, people with black and blue eyes will not have children with blue eyes.
Eyelashes: Long eyelashes are also dominantly inherited. As long as one parent has long eyelashes, the possibility of a child inheriting long eyelashes is very large.
Nose: Generally speaking, the nose is large and high, and the nostrils are wide and dominantly inherited. One of the parents has a straight nose bridge, and it is very likely that it will be passed on to the child. The genetics of the nose continue into adulthood, and when you are a child, you have a short nose and an adult may become a tall nose.
Ears: The shape of the ears is inherited, and the large ears are dominantly inherited relative to the small ears. As long as one of the parents has big ears, then the child is most likely to have a pair of big ears.
Jaw: Is a dominant inheritance that is not "negotiable". Either parent has a prominent large chin, and the children often have a similar chin without exception, which is "like" a little bizarre.
Obesity: It will give children a 53% chance of becoming a big fat person, and if one of the parents is obese, the probability of the child being obese drops to 40%. This shows that about half of the fat and not fat can be determined by human factors, so parents can make their posture even through a reasonable diet and full exercise.
Baldness: The Creator seems to favor women, allowing baldness to pass only to men. For example, if the father is bald, there is a 50% probability of passing it on to his son, and even the father of the mother will leave 25% of his baldness to his grandchildren.
Acne: This facial disease that makes young boys and girls angry is actually related to heredity. Because if both parents have suffered from acne, the prevalence of their children will be 20 times higher than those without family history.
Leg shape: A leg that resembles the fat accumulation of parents, and can be shaped into a slender and strong leg through adequate exercise. However, if the legs appear too long or too short due to genetics, they can no longer be shaped, and they can only resign themselves to nature.
How to optimize your genes before your baby is born?
01. My husband and I are quite dark-looking, but I don't want the baby I give birth to to be a black angel.
Black couples want to have white babies, pregnant women can eat more vitamin C-rich foods. Vitamin C interferes with the production of melanin in the skin, reduces melanin precipitation, and the baby's skin will be white and delicate.
Recommended foods: tomatoes, grapes, citrus, cauliflower, winter melon, onions, garlic, apples, prickly pears, fresh dates and other vegetables and fruits, of which apples are the best.
02. My husband and I are dry skin, and it is easy to crack in the winter, how can we keep the baby from this sin?
Couples have rough skin, pregnant women should often eat foods rich in vitamin A, which can protect the skin epithelial cells and make the child's skin delicate and shiny in the future.
Recommended food: Animal liver, egg yolk milk, carrot, tomato, green vegetables, fruits, dried fruits and vegetable oils.
03. My family has the gene of inheriting yellow hair, my sister's child is still yellow when she is one year old, will my baby also be inherited like this?
If the couple's hair is not good, pregnant women can eat more foods containing vitamin B, which can improve the child's hair quality, not only thick, dark, but also shiny and shiny.
