What are the main types of genetic selection

Genetic selection is mainly the following:

(a) improve the success rate of selection

The core of scientific selection is prediction, there is no prediction, there is no selection. Because individuals with athletic talent, is not a lifetime down to show obvious sports advantages, is with the individual growth and development process, and in sports training and other environmental conditions *** with the role of the gradual performance, until a certain age and training level, in order to create a brilliant athletic performance. Therefore, in the early selection, only through the pre-selected for a comprehensive and accurate prediction, to judge the best possible future performance, in order to decide the selection of the object of the trade-offs. Genetic selection is based on the heritability, relevance, specificity of the traits that make up the human body's athletic ability and their stages of expression in the process of individual growth and development, and in accordance with the specific innate qualities required for different sports to select sports seedlings, so as to make the prediction more scientific, to improve the success rate of the selection of materials, and to reduce the elimination rate.

(2) Improve the efficiency of selection

Soviet scholar H.H. Bulgakova (1978) has written an article on the complexity of finding sports geniuses, in a million children and teenagers of the same age and gender, in order to select an individual with ideal height, speed and agility. What's more, modern competitive sports have higher requirements for athletes' physical, intellectual and psychological qualities, which makes the selection process even more difficult and complex.

Particularly with the modern competitive sports performance age in advance, and cultivate a good athlete still have to go through about 8 to 10 years of systematic training, which requires more scientific selection. As we all know, the younger the age of the selection of the more difficult, because individuals with athletic talent must reach a certain age in order to reveal the unique athletic talent. If selection tests are conducted one by one among millions of children, it is bound to take a lot of time and consume a lot of manpower and material resources, thus making it impossible to realize efficient selection. On the contrary, if in accordance with the principles of human genetics for selection, the focus of selection to those children born of parents with strong athletic ability, can accordingly narrow the scope of selection, improve the efficiency of selection to achieve time and effort, which has been proved by many domestic and foreign champions of the world its feasibility.

(C) mining sports potential, eliminate genetic hazards

As children and teenagers growth and development of the climax of the beginning of the time of the early and late show obvious individual differences, only by intuition and experience in the selection of materials, often those who are early to start the development of the type of individuals selected for the sports team, and some of the athletic talent of the normal development of the type of development or delayed development of the type of children rejected the door, burying their sports talent. The athletic talent of these children is buried. Our scholars Liu Xianwu, Zeng Fanhui and other research shows that the early start of development type of the lowest rate of success (4%); normal start of development type of the highest rate of success (90%), especially the normal start of the development of the extended type of success rate of up to 65%, such as China's Zhu Jianhua, Liu Yunpeng, Liu Haixing, Lin Zhiming and so on are of this type. If the selection of genetic factors, give full consideration to the selection of the family's athletic ability, it can be children have not yet revealed the potential of the sport to dig out, and then improve the selection of the success rate.
