The dangers of mixed race

There are many mixed-race children in life. Mixed-race children are children born from parents who are not from the same country or from people with different blood relations in their ancestors. If mixed-race children are born well, they will be very beautiful. If they are not born well, they may look very ugly. Some people say that there are too many factors in the blood of mixed-race children. So what are the dangers of mixed-race children?

From a biological point of view, first of all, mixed-race children have too many dominant genes. These dominant genes include not only excellent genes, but also disease genes. Therefore, the probability of disease dominance is much higher than that of purebreds.

Secondly, since they inherit both paternal and maternal disease genes, they have more disease genes than purebreds, but most of them are hidden, but they do exist. It won’t show in the first generation of mixed-bloods, but it will show in the second, third, and other generations.

In fact, the above also reflects from the side that the genotype and phenotype of mixed-bloods are more discrete than those of pure-bloods. The good mixed-bloods are very good, and the bad mixed-bloods are even worse!

Then why are all hybrid rices of excellent quality? In fact, the good hybrid rices are better and the bad hybrid rices are worse. It’s just that hybrid rice has been artificially selected, and the average and worse ones have been discarded, which is why it performs better as a group. This is the essence of hybridization.

But it’s different with humans, because the average half-breeds and worse half-breeds cannot be eliminated, because you can’t kill them.

So the first generation of mixed-race children are not so bad because they have complementary advantages. But after the second generation, the complementary advantages gradually disappear, the harm of gene dispersion begins to manifest, and the probability of complications is much higher than that of purebreds.

Raising a mixed-race child is like gambling, you win for a while but lose for the rest of your life. In addition, most people now have only one or two children, so the single-line inheritance cannot afford the risk of dispersion! Once it occurs, it basically means that the inheritance will be broken.

Although individuals or families cannot afford this risk, society and groups can.

Because society itself has the function of selection and elimination, society has multiple options. Eliminating the bad ones will have no impact on society, because the good ones will fill the gap and gain more room for development.

In biology, several concepts need to be clarified:

1. The harm of inbreeding is relative to normal reproduction, not to hybrid reproduction. Hybrid breeding and inbreeding each have their own advantages and disadvantages, and the two cannot be compared. But from the perspective of evolutionary results, hybridization can acquire new genetic diversity, while inbreeding is to stabilize excellent genotypes. The failed products they produce need to be eliminated, otherwise they will be meaningless and insolvent.

2. Beauty is not completely equal to health, because beauty is largely influenced by aesthetics, and aesthetics is influenced by economy, culture and military. People like you only if you are strong, but if you are not strong, it is not necessarily because of bad genes, it is more likely a problem of opportunity and time.
