Dalmatian Dog (confirmed introduction)
We understand that under normal circumstances, it is not recommended to match the first blood relatives, because the offspring born from the first blood marriage will be The chances of children suffering from dullness and abnormality are much higher. But dogs are different. Dogs can bring a lot of benefits if they grow up as direct relatives. So what exactly are the advantages of matching a dog with a close relative? Let’s take a closer look.
1. Homozygous genes that control good traits are the key to eugenics. According to the genetic sequence, when direct relatives match, both genes for good traits and disease-causing genes are likely to be homozygous. While bad offspring are produced, homozygous offspring with good traits are also produced. This conclusion is not uncommon in the investigation of direct kinship matching. The offspring with undesirable traits are naturally adopted, and the unfit ones are eliminated, while only the offspring with good traits that suit the environment remain. In this way, the selection from generation to generation can obtain excellent offspring. This has to be a eugenic path. In real life, why are there so many descendants with undesirable traits? The main reason is that artificial control of direct-blood matching causes many genes for undesirable traits to be hidden in the offspring, instead of being removed through natural selection. There are more genes than genes for good traits. On the contrary, plants generally self-pollinate in the natural environment, and some of their undesirable traits are eliminated in the process of breeding. Therefore, the probability of plants producing offspring with undesirable traits during self-pollination and breeding is higher than that of humans. It's so small that it can even be ignored.
2. Gene homozygosity for good traits can produce new natural human populations and good individuals preserved in natural selection. Carry out natural reproductive separation, that is, direct biological growth. During the growth process, new excellent genes are homozygous and retained; at the same time, the excellent mutation genes produced are manifested through the growth of direct relatives, making the genes homozygous, and then through geographical separation, it is possible to produce new natural human populations. Then it accelerates the evolutionary process of natural people and enables natural people to evolve to a higher level. At present, why are human populations not as diverse as other animals? And the animal kingdom is not as diverse as the animal kingdom? The main reason is that artificial control of first-blood mating hides the original genes and evolutionary genes in the human population, and New traits cannot be expressed, that is, new individuals cannot be produced. Therefore, the human population is not as diverse as other animals. People and animals can walk and live in other places away from their original place of growth, but animals can only grow locally. Therefore, it is not as easy for humans and animals to undergo reproductive separation and geographical separation as for animals, and it is not as easy for humans and animals to produce new populations as for animals.Therefore, forming varieties of humans and animals is not complicated.
3. The growth of direct relatives makes genes homozygous. Through natural adoption, the stability of the earth's ecological system is protected. After the growth of direct relatives, alleles are homozygous. Individual undesirable traits that occur are not consistent with the situation and are eliminated. Remove. Excellent individuals survive in accordance with the environment. Therefore, the overall number of natural human populations will not suddenly increase, allowing the ecosystem to adopt this natural arrangement to maintain the ecological stability of the system. Therefore, direct biological growth can achieve the stability of the earth's ecological system through natural adoption.
