Intermarriage between inbreeds
According to media reports: The Hanjiang County People's Court publicly pronounced a judgment on a 13-year marriage invalidity case, the reason is because the relationship between the man and the woman in the marriage is a cousin, to put it simply, the state explicitly prohibits the marriage of close relatives, why is the marriage between close relatives prohibited, what harm it will cause, and listen to the universe in detail.
As we all know, there are billions of beings on the earth, and these lives reproduce and pass on from generation to generation in a limited time, and the same is true of human beings. However, humans and other creatures are more special, because human genes have functions that many organisms do not have.
The role of DNA
What we call genes, is DNA, it is also known as DNA, it is a macromolecular polymer composed of RNA and proteins, everything in the human body comes from the role of genes, its impact on you is definitely not a little bit, such as your temper, personality, hobbies and eating habits, daily routines, are controlled by genes.
It is worth mentioning that even our bodies are controlled by genes inside the body. When you will grow tall, when you will get sick, when you will die, all because of the role of genes, and genes are hereditary, which means that genes can create countless offspring.
Inheritance of chromosomes
Genes are hereditary, which is why children and their parents look very similar, humans have 23 pairs of chromosomes, 46 individual chromosomes, and you inherit half of the chromosomes of your father and mother, which is why sometimes children look like fathers, but their temper and hobbies follow their mothers.
Principles of Paternity Testing
In the same way, genes in the process of inheritance, will produce genetic mutations, creating genes at different points, and because of this, under the action of genes, human scientists have created paternity tests. The role of personal identification is to extract secretions containing fragments of father and child DNA, which can be blood, sweat and other components.
Then through big data, the two sets of genes are digitally analyzed, and then the genes of the two are paired, and the gene fragments of the two cannot be completely matched, but the number of point errors in the fragments cannot exceed 3, once exceeded, it means that the two are not related by blood, such as 1-2, which means that it is absolutely the biological father and son, because the error of 1-2 originates from the mutation of the gene.
It is the gene that has the role of mutation, and every time it is passed on, the gene will mutate, and this mutation will not make the mutilated parts of the DNA fragment paired, and in doing so, the mutilated gene fragments cannot be activated.
The mutilated gene is activated
But if close relatives marry, there is a high probability that this wrong birth will be activated. Scientists call it the autosomal recessive inheritance of genes, as we said earlier, in the process of inheritance of genes, genetic mutations will occur, and the role of gene mutations is to combine the best causes and give up the worst genes.
When the two inbreeds intermarry, because the body of both of them contains genetic fragments from both relatives, this fragment is likely to be activated after combination, and this fragment of disability will largely trigger congenital diseases.
What is intermarriage between inbreeds
Intermarriage refers to the blood relationship between immediate relatives within three generations or within three generations, because in this range, autosomal recessive inheritance can easily be activated, which is why after intermarriage, the children born after intermarriage are either suffering from congenital diseases or premature death.
Imagine if a team of couples did that, that's it. But if all of humanity did this, the consequences would be catastrophic, because intermarriage kills genetic mutations and cannot create more and better genes.
Inheritance and genetic mutations
Let's take a simple example, A and B have intermarriage, then their offspring, can only inherit the genes of A and B, if A and B do not have inbreeding, then their offspring may be C and D, and then C and D and then marry other people, can create E and F, so that under the inheritance of genes, gene mutations will pass on high-quality genes, damaged or mutilated genes are buried in the long river of history.
This article summarizes
However, the damaged gene is not unable to activate, only need to find the same type of gene fragments, once the two are combined, can immediately activate the mutilated gene, and the activation condition is: inbreeding intermarriage. That's why the 13-year marriage was invalidated by the court.
