Damaicho Dog (detail introduction)
We know that in general, it is not advocated that close relatives get married, because children born in close relatives get more likely to suffer from dementia and deformity. But the dogs are different, but the dog's close relatives can bring a lot of benefits. So what are the specific benefits of dogs and get married? Let's find out together.
First, the genetic innocence that controls the excellent character is an important way for eugenics. According to genetic laws, the marriage of close relatives is easy to pure in both the genetic or pathogenic genes. While generating bad offspring, it also produces a purely synthesis of excellent character descendants. In the survey of close relatives, it is not difficult to draw this conclusion. The descendants of bad presences are eliminated through natural selection, and the uncomfortable people are eliminated. The choice of this generation can get excellent offspring. This has to be a way of eugenics. In real life, why are there many offspring that produce bad priorities? The main reason is that artificially restricts the marriage of close relatives, so that many bad genes are hidden in the offspring, and they are not eliminated in natural choices. There are more genes than excellent traits. On the contrary, in the natural environment, most of the plants have self -pollination, and their adverse individuals are eliminated in the transmission generation. Therefore, the probability of plants in the self -flower pollination and passing generation is better than Humanity can even ignore it.
Second, the genetic innocence of excellent traits can produce a new natural person's excellent individual that is preserved in natural selection. Natural reproduction isolation, that is, close relatives breeding. The new excellent genes in the breeding process can be preserved purely; at the same time, the excellent mutant genes produced by close relatives make genes pure synthesis, and then through geographical isolation, a new natural population may be formed. So as to speed up the evolution of natural people and make natural persons evolve to the first level. At present, why do human species have no other types of animals? And there are many species in the animal world without the plant world? The main reason is that human restrictions on the marriage of close relatives, so that the genes and mutations in the human species in the human breeds are hidden without expressing it. New traits cannot produce new individuals. Therefore, there are many types of human species without other animals. People and animals can walk, leave the original growing place to live in another place, and plants can only grow in place. Therefore, human and animals are not as easy to form reproductive and geographical isolation as plants, and people and animals are not as easy to produce new populations as plants. Therefore, there are many types of people and animals.
Third, close relative breeding makes the gene pure convergence. Through the natural selection of the balance of the earth's ecosystem, through close relative reproduction, the genetic pure convergence of the same level of genes produces the disproportionate individual, which is eliminated due to the failure to adapt to the environment. Excellent individuals adapt to the environment and save it. Therefore, the overall number of natural population population will not suddenly increase, so that the ecosystem uses this natural adjustment method to maintain the ecological balance of the system. Therefore, through the natural selection of close relatives, the balance of the earth's ecosystem can be achieved.
