People can often hear such saying:
Boys are like mom, girls are like Dad
“Baby’s IQ is inherited from mom and character from Dad”
Is the power of genes so magical? Can genes really be perfectly reproduced? Today, let’s take a closer look.
Boys are like mom, girls are like Dad
In fact, the heredity of our looks and figure is not clear in a word or two!
As we all know, each of us is developing from the fertilized egg. In the formation of the fertilized egg, it becomes “we”, which will pass a random combination, division, exchange, mutation, combination of multiple genes and chromosomes, and combine a new individual that is unpredictable and unique.
So, from the eyes of the eyes, nose, mouth, ear, eyelashes, etc., the fat and thin equity characteristics, will be biased, depending on what kind of genetic factor we allocated from your parents.
Skin colour
The inheritance of skin color is mostly to neutralize the skin color of parents. The parent are white, another side black, the next generation may be in the medium, but occasionally more biased to someone’s skin color.
However, if the parents’ skin is dark, the children’s skin color is often not very white.
Double eyelid
Double eyelid is a “lucky gene”. If both parents are double eyelids, most children are double eyelids. Even if they were single eyelids when they were young, they may gradually become double eyelids with age. Of course, it is also possible to have a single eyelid all the time.
If both parents have single eyelids, the probability that the child has double eyelids is very small.
In addition, big eyes, Roman nose, long eyelashes, dimples and so on are also the same as double eyelids. If one parent has them, the child is very likely to inherit them. ShaoBaiTou is a typical counterexample, which belongs to genes that are not easy to be inherited.
Height
You need to know that, the height of children is determined by the height of their parents.
In clinical practice, FPH formula is often used to predict the adult height range of children: the target height of boys (CM) = 45.99 + 0.78 ×（ Father’s height + mother’s height) / 2, girl’s target height = 37.85 + 0.75 ×（ Father height + mother height) / 2.
It should be noted that genes only determine the trend and range of height growth, and finally determine height in combination with living environment, sleep, sports activities, nutritional diet and other factors.
Therefore, parents should pay more attention to their children’s reasonable diet and moderate exercise.
Obesity
It has to be said that obesity is the easiest to inherit, because many obesity susceptibility genes are important reasons for the development of obesity.
Although we can’t change our genes, we can reduce the risk of obesity through our own efforts, such as strengthening sports, reducing the intake of high calorie food, refusing to sit for a long time, etc.
Bald Head
Baldness is a special inheritance. Usually only boys have the performance of “baldness”, while girls only have heredity and do not show obvious “baldness”.
“Baby’s IQ is inherited from mom and character from Dad”
It is clear that IQ can indeed be inherited.
Frontier Science has published a research that intelligence is the core component of cognitive ability, which has a high heritability.
However, the distribution of genes is random and complex, which can not predict who will inherit the IQ, or even ensure that the genes with high intelligence will be passed on to the next generation. Although the level of parents’ IQ can not determine the absolute value of the IQ of the next generation, it affects the potential of children’s IQ. It is not impossible to stimulate this potential and give full play to its maximum benefits under the education and cultivation of the day after tomorrow! Similarly, the role of acquired culture is even greater than that of genetic inheritance.
Beware that these diseases may be inherited
Myopia
The principle of myopia is that excessive use of eyes for a long time makes the ciliary muscle in a spasm state, so it can’t relax to its original position.
High myopia is a multifactorial and / or single gene genetic disease. Its genetic modes include autosomal dominant inheritance, autosomal recessive inheritance and sex linked recessive inheritance.
In addition to genetic reasons, excessive eye use, reading too close to books, lying down and other wrong reading posture will lead to vision loss.
There are many hazards of myopia, such as decreased visual sensitivity, strabismus, glaucoma, and lens opacity.
Therefore, parents must pay attention to their children’s eye habits, use their eyes scientifically and reduce the incidence of myopia.
Hypertension
It is self-evident that in 1994, the Chinese Journal of Medical Genetics published that hypertension is generally considered to have family background and genetic tendency. The incidence rate of hypertension is 3.1% for both parents, while the probability of hypertension for parents with healthy parents is only about 20%-45%.
There may be no symptoms in the early stage of hypertension, but it imperceptibly damages the heart, brain, kidney and other organs, eventually leading to stroke or myocardial infarction, and even death, which can be called “killing invisible”.
Therefore, we must adhere to regular physical examinations, early detection, early prevention, and early treatment.
Breast cancer
Breast cancer is a common malignant tumor in women. Epidemiological survey data show that there is a family clustering phenomenon in the incidence of breast cancer. 15%-20% of breast cancer patients have a family history of breast cancer.
Women who do not have a family history of breast cancer should also pay attention to regular breast examinations.
Depression
The prevalence of patients with affective disorder and first-degree relatives is higher than that of second-degree relatives, and the prevalence of relatives is higher than that of ordinary people.
In other words, the closer the blood relationship, the higher the prevalence of depression.
Regarding depression, full understanding and care from the outside world will reduce the incidence to a certain extent. You should also pay more attention to your own inner health, don’t give up on yourself, and discover the beauty in life with your heart.
In summary
The saying that boys are like moms and girls are like dads is not credible. To whom the child will be biased depends on the genetic factors allocated from the parents. Instead, we should be concerned about the diseases that parents may pass on to their children. Regular physical examination, timely detection and early treatment.
