Labemi kunye nendlela zamanani uphando. Ukuba isifundo yemfuzo indlela labantu-manani?

Iipateni yelifa uphawu ahlukeneyo emzimbeni womntu uphonononga yesebe eziphilayo - imizila yemfuza zabantu. It ngokusondeleyo ukuya amalungu, amayeza, okusingqongileyo kwaye yenzelwe ukusombulula iingxaki ucupho kunye isifo yokuqala ezimbi, zibangelwa aberrations kwi lezakhi kwamanani abantu - chromosomal, iimfuzo zofuzo lofuzo. Labemi kunye indlela manani yenye ndlela engqiniweyo ucupho kunye noqikelelo olumalunga syndromes - ngezifo ilifa, ukufunda yaye iya malinikelwe kulo nqaku.

Iimpawu ze indlela yesicelo

Genetics Medical umsebenzi wayo bathelela iintlobo ezahlukeneyo zabantu izixhobo zophando chromosome, zokuzoba idatha Sciences ngqo, amanani kunye namayeza clinical. Ngoko ke akukho ngozi isiseko theoretical component yemfuza lwabemi kunye nemithetho yayo laliqulunqwe ngoncedo uhlalutyo zezibalo. Labemi-manani ndlela isetyenziswa kuphela ukukhangela ukungaqheleki yemfuza, kodwa ukufumanisa amaza kukuvela yemfuza ukufukama ezi ukuphazamiseka njengomqathango homozygous sofuzo, kwaye (common kakhulu), heterozygous hayi masibonise ifomu phenotypic.

Ingcamango labantu

Ukufaka iipateni zemathematika yokubuyekezwa uphawu ezithile njengelifa lezakhi, imfuza wabhenela ingqikelelo inani labemi abangabantu. Ziziphi iindlela izinto ezifunwa kakhulu kwinzululwazi mihla ukufunda ngayo? Ziziphi izinto ezintathu ezibalulekileyo:

1. Abemi-manani indlela.

2. Nohlanga.

3. Twin.

Phantsi lezakhi ukuqonda genotypes yabo bonke abantu abahlala kwindawo ethile. Lo isenokuba abemi kwilizwe liphela, uhlanga okanye iqela labantu ohlala ngokwaneleyo zodwa, umzekelo, abahlali lali yalahleka kwiintaba Afghanistan okanye isizwe ehlathini Amazon.

Le abalinganiswa genotypic yabantu engena isethi yonke genes and iimpawu zangaphandle abantu bayo. Labemi kunye nendlela manani uphando isicelo ekufundweni zombini ukungaqheleki manqapha kunye nabo uhlobo ecacileyo ngokwemilibo yoboniso.

Iqela lokuqala kwenzeka ngenxa yokuba isimo teratogens. Elinye iqela iquka uluhlu olubanzi mgceni, leyo ibhalwe ngendlela ngendlela ethile entsatsheni, uhlanga, ubuzwe, ixesha ngokwaneleyo elide. Umzekelo, polydactyly, ubumfama, kubazali bakhe. Ukufunda indlela yokosulela uphawu zophendlo lwezifo zamafa ukulawula ezi zifo populjatsionno kusetyenziswa indlela manani.

Imiba echaphazela imbonakalo sezifo yofuzo

Medicine nature multifactorial kwaba (zombini yemfuza nokusingqongileyo) ezimbi ukuba azibonakalisa eziliqela izizukulwana ezininzi zabantu. Uhlalutyo Genetic nomfutho, uhlobo I seswekile, isifuba, ngesifo kunye nezinye izifo kunye ukuthambekela amafa kufuna isifundo amawaka ukuzalwa.

Izakhi manani Kwimeko nganye populjatsionno indlela uyakwazi ukubona umgangatho ngayo abantu iqela isiphumo imiba yokusingqongileyo (radiation microelement ukwakhiwa okusela amanzi, kwemozulu) kwaye ubone ukuba ichaziwe zingaphi yemfuza.

Ngaba yezifo ezinxulumene ukungafani genetic labantu

Yintoni iziphumo inika ucazululo lokuthelekisa amaqela ahlukeneyo ngokobuhlanga abahlala iimeko ezifanayo esingqongileyo? Ziyahluka njengempendulo abantu ezo zinto ezifanayo abiotic bubungqina ukungafani yazo yemfuza.

Lwezonyango, usapho kunye abemi indlela manani ukuba isifundo yemfuza zabantu zibonise ukuba umgangatho ngokubonakala sifo iintsapho ifaniswe frequency yayo ingenzeka abakhoyo. Zisetyenziswa ekufundeni rheumatism yemfuza ukuthambekela, aleji, ngokunjalo nezifundo kwezonyango loluntu lichaphazeleke zizifo multifactorial: sclerosis,-Alzheimer, Autism.

ukugwetyelwa Mathematical belifa

Phambi kokuba kuqwalaselwe yemfuzo ethile kwamanani abantu, sifunda sikhokelo theoretical component thaca ngokohlobo umthetho zezibalo. umongo wayo ngolu hlobo lulandelayo: Le rhoqo genotypes ngokwendlela nayiphi na zofuzo kungabalelwa ngokusebenzisa i equation kubalwa sikwere amanani amabini. Noko ke, le labemi kufuneka zibe nkulu ngokwaneleyo, akangekhe yemfuza isikhephe zivunywa imikhosi kunye ukusukelwa kwenzeka ngokuzenzekelayo.

Ukusebenzisa indlela abemi-manani lokufundisisa yemfuza oluntu kunye neziphumo kuqwalaselwe zonyango, kunokwenzeka ukuba ukuqikelela amaza yokuvakalisa phenotypic ngezakhi njengesonakeleyo, kunye nokwenzeka ukuba umntwana ngezifo.

Indlela yokubala amathuba izifo

Nanku umzekelo ilifa phenylketonuria - izifo yemfuza, nto leyo esekelwe phezu ukwabelana ukungathobeli acid kubalulekile acid phenylalanine. Xa inane abemi baseYurophu ezingaqhelekanga gene livela frequency f ngu-1: 10,000 izigulane homozygous sofuzo kweejini ff.

Usebenzisa eceliwe labemi-manani, kunye izibalo, kunokwenzeka ukucwangcisa amaza sofuzo engaqhelekanga. Kuyinto ilingana 0,01. Ke amathuba phawu kuchazwe phenotype, ngu 0,99. Ngenxa yoko ke, babethwele sofuzo, Ngokuba kweejini Ff, kwenza 0,02. Oko kukuthi, kule abemi malunga nama-2% abantu abaye baphila kweejini gene lwabo sofuzo ukuba phenylketonuria.

Njengoko sibona, indlela abemi-manani ukubala amaza zofuzo abemi panmictic onoxanduva amazwi ezimbi zamafa.

Iimpawu kwamanani abantu

Kwemvelo lasisiseko senkcubeko yoluntu, ekusekeni taxon zebhayoloji, angamelwa njengoko uphuhliso loluntu ngamnye, ixesha elide ezihlala kwiimeko bume efanayo. Ziquka climatogeographic iparameters efanayo, ngendlela enye ngokutya, kwamagciwane eqhelekileyo.

Konke oku negalelo liluhlanganise lezakhi kwemiphakathi amaqela alleles eziqhelekileyo kunye izibini kwi zigaba zokuqala anthropogenesis yaba isiseko isenzo kweendidi ilifa yokwahluka zivunywa.

Ukuba isifundo yemfuzo labemi kunye neendlela manani ngoku? Okokuqala, ukuba umphumo zofuzo abantu kunyanzeleka Ukuqhela kwemitshato ezinxulumene ngokusondeleyo, ukuhla komgangatho wemo engqongileyo. Baya kwakhokelela lezakhi yabantu sisindwa izakhi ezingaqhelekanga Wasazisa nokudalwa thethwano lwezonyango-genetic kothungelwano olubanzi eyenzelwe ukuchonga yofuzo ukuya ngokubonakala zizifo ezahlukahlukeneyo.
