There is a saying, "Genetic advantage is greater than acquired effort", which shows the importance of genes. After all, to understand human heredity, we need to understand the relationship between genes and DNA.
Since 1953, when Alfred Hershey and Martha Chase proved DNA, human beings have understood that the carrier of genetic information is DNA, and genes are important units to measure heredity. The proof of DNA has also virtually broken many human conjectures, and with this research, it is of great significance for human beings to explore many diseases.
In everyone's concept, good genes can be inherited and bad genes can be inherited, and this is the characteristic brought by genes.
And we have also seen a lot of "ugly genes" from celebrities, no matter how beautiful the wife is, it can't be saved.
A gene is an important unit in the molecular chain of DNA. To put it simply, it is a double helix structure composed of two polynucleic acids, of which there are hundreds of thousands to millions. Let's describe the DNA molecule as a bus, and the section from one station to another is the gene.
Scientists believe that there are about 50,000 to 100,000 genes in a DNA molecule. Therefore, for us humans, the strength of genes can almost determine our facial features, characteristics, etc.
Genetic inheritance is very complex, and it is related to people's speech, thoughts, feelings, and actions, which almost encompass our daily behavior. Of course, what everyone is most concerned about is the power of the inheritance of "ugly genes".
Many people find such a strange phenomenon that ugliness is easier to inherit than beauty, why is this?
Let's take the big star Jackie Chan as an example, Jackie Chan has a very obvious feature, such as a big nose, which is related to the nickname "Big Nose" that everyone gave him when Jackie Chan joined the "Seven Little Blessings".
When he was young, Jackie Chan had many girlfriends, and his wife Lin Fengjiao was one of them, this is a typical temperament beauty, and Jackie Chan has a son.
In addition, Jackie Chan and beauty pageant champion Wu Qili also gave birth to a daughter, who is nothing more than his illegitimate daughter. Even if they were not born to the same mother, they all inherited Jackie Chan's big nose, which is the peculiarity of genetic inheritance.
Of course, there is not only one example of the big star Jackie Chan, but there are still many examples in the star circle. And this gene inheritance law is related.
The author has read a book called Romantic Genes, and you can listen to the historical causes of the genetic inheritance of ancient ancestors. It shows that humans came out of the African savannah, and also analyzes the causes of genetic diseases in different regions.
You will find out how human beings measure the earth with their feet, and how to have a romantic encounter with genes, language, and culture in the process, and build human history and culture.
Since ancient times, there has been a saying, "The parents who suffer from the body do not dare to destroy the beginning of filial piety," and we love our own body, which is to honor our parents.
Everyone is unique, even if there are imperfections, we have to accept that we are different fireworks.
Children will inherit the genes of their biological parents, and acquired factors only account for a part, and we will now analyze them from height, appearance, weight, IQ, etc.
First of all, looking at height, it was found that one of the parents was 3% shorter than their peers, and the height of the child would also be lower.
There is a basis for this, genetics has found that 35% of height is genetically determined, and 30% is determined by the environment. Of course, it is very important for parents to give their children enough nutrition to improve their body's immunity.
In terms of appearance, eye size, hairstyle, and color are the ones with the highest genetic probability. For example, if one parent has big eyes, the probability of the child having big eyes is 50%-100%.
*This can be seen from different races, and children born to blacks and whites are more likely to inherit blacks.
Looking at weight again, in addition to the fact that appearance is more affected by genetics, the impact on weight is also obvious. Generally speaking, both parents are obese, and the probability of children being obese is also very high. A survey showed that only 3% of obese people succeed in trying to ** within 5 years. Therefore, it is not exercise and diet that are not the direct causes of obesity.
Now let's talk about IQ, from the perspective of human development, the environment, education, and acquired efforts are all indispensable. This is related to the fact that the acquired environment is 10% higher than the genetic inheritance.
In short, the influence of genes exists, but I am not absolute, and we still have to work hard to change it.
The "ugly gene" is a powerful problem, we need to have a clear understanding, no matter how beautiful it is, the wisdom and experience of the gene will not be passed on to you. Any time you work hard, you can determine the important criteria of your life. In fact, the field of genetic exploration will bring great advantages to the characters, especially the medical side is crucial.
