This problem itself is put in a lot of trap, after I differentiate carefully, the look answers you.
Above all, the gene of top athlete is very powerful for certain, as an Everyman, how do you drill again also do not run to cross Boerte, the gene that the reason is a family is very more too much than you.
Next, athletic gene of the black is very powerful also, their limb compares someone else generally longer, suit ran more. Their also compare someone else with tendon longer, fit bouncing project more, wait a moment etc.
The 3rd, if close two afore-mentioned issues, ask " the gene of black athlete has many powerful " , the answer is to do not have so powerful, when because become you,talking about a black, those who talk about is " phyletic " , this is a collective feature, those who look is average; But when you talk about top athlete, those who talk about is to seldom count an unusually lucky person, this is an individual feature, those who look is special case, both have substaintial distinction.
Specific for, group feature basically is curve of form of a bell, the major person in the group is in intermediate position, the person that is located in the connate different report on tail of bell form curve be in the minority, the professional arises from inside latter. The photograph of bell form curve of black group and other group is compared, its average has difference, the black on whole is so betterer than the athletic gene of someone else, but if see the tail of bell form curve only, each crowds are about the same, if be good at from the word that the good young plant that has athletic talent chooses to try to foster over there the tail, each crowds should OK education goes fine athlete.
A particular case cites below: A person can walk after all much faster, depend on greatly his muscle type. Skeletal flesh of the mankind can be divided roughly for fast flesh and slow flesh these two kinds, former erupt force is powerful but not abiding, latter is antipodal. The outbreak of skeletal flesh force still depends on α - complementary actin - 3 (ACTN3) type, this kind of albumen among fiber of consist in fast flesh, there is two to plant in human group main inferior model, code by R gene and X gene place respectively. The albumen that R gene codes erupts force is more powerful, x gene is relatively a few poorer. From theoretic tell, the person that has RR genotype erupts force is the most powerful, XX is the poorest, RX uprights at both between.
Published in 2001 " human element genetics " a paper on the magazine shows, the X of ACTN3 gene inferior model the occurrence frequency between East Asia person is about 52% , the white man is 42% , african is 16% . That is to say, the proportion that RR genotype holds among East Asia person is only 25% , european be 36% , african is as high as 60% . If random ground chooses a child to go,drill dash, in other condition same situation falls, of African child become a useful person rate should compare East Asia child one times taller much.
Actual condition should compare this difference bigger, the regnant force that black player gets on in dash project is clearly, the reason depends on, it is African likewise, different area is having completely different genotype. At present majority dash ace comes from West Africa, belong to Bantu (Bantu) unborn. In fact, is player of the first blame West Africa that runs into 9 seconds area the Fulanji that comes from Namibia? Fred Li Kesi (Frankie Fredericks) , time was 1991. End so far, the whole world enters the person that ancestral home is not West Africa among 98 athletes of 9 seconds club to have 6 only, among them a Su Bingtian that is China.
Why is difference such big? From ACTN3 gene distributing to see among them reason not hard. The X of ACTN3 gene inferior model the frequency between West Africa Bantu is only 1% , that is to say, almost the latent capacity that all Bantu offspring are RR genotype! Want to know, player of a dash should see his genotype not only, function of lungs of the type of build or figure that sees him even, heart and skeletal intensity wait a lot of index a moment. The Bantu that comes from West Africa wants other condition only pretty good can drill dash, because he is of RR genotype for certain almost. Jamaica teems with dash ace, a very big reason depends on this is the central america insularity that receives African slave the earliest, and inchoate African slave comes from West Africa mostly.
Can see from this case, the black runs quickly, main reason is the proportion that good genotype has among group of West Africa black very tall, select material is easy. But specific to the individual, su Bingtian also can be RR for certain almost model person, choose in this respect and top Black people the hand is same. Say so, if think education gives an East Asia player that runs quickly, should analyse genotype first before select material, winkle is located in the person on tail of bell form curve, such person scale is inferior among East Asia crowd, but if be carried carefully or can winkle and black tip player are about the same of good young plant of the condition.
