Heluna kanaka a me ka ana helu iaoia o ka noiʻi. I ka like o aaiaoe? O ka heluna kanaka-ana helu hana?

Kumu hoohalike o ka'āina hoʻoili o ka okoa kāna moʻolelo i loko o ka kanaka kino kaupaona i nā ka lala o ka kālaimeaola - kanaka aaiaoe?. Ua Ua pili loa aku i ka physiology, lāʻau lapaʻau, ka i hoʻolilo 'ia a me ka ua papahana e ke hoʻoponopono i nā pilikia o ka loaʻaʻana, a kakahiakaʻike, o pathologies, kena ae la ia e aberrations ma ka'ōewe wai auau o kanaka populations - chromosomal, aaiaoe a me ka genomic mutations. Heluna kanaka a me ka ana helu iaoia o kekahi o ka loa ai ke ano o ka loaʻaʻana a me ka wānana 'ana o syndromes - hereditary kanaka maʻi, hoʻopaʻa haʻawina ia, a e e hoolilo i keia' atikala.

Hiʻona o ka palapala noi iaoiaeii

Lapaʻau o aaiaoe? I loko o kona hana io i kekahi mau ano o kanaka chromosome noiʻi i hoʻomākaukauʻia, unuhi aku la ia i ka 'ikepili o ka kiko'ī sciences,' ikepili helu a me ka lapaʻau lapaau. He ole ulia i kaʻimi naʻauao muli o ka heluna kanaka aaiaoe? A me kona kānāwai i ua kālaiʻia a me ke kōkua o makemakika Ka Ikepili. Heluna-ana helu iaoia ua hoʻohana 'ole wale e hōʻike aaiaoe abnormalities, akā, no hoi, e hooholo i ke alapine (frequency) o ka hanana o nā'ōewe harboring mau kāna hana e like me ka homozygous recessive ana, a (oi, he pono ole), heterozygous i hoike i ka phenotypic palapala.

I ka manaʻo o ka heluna kanaka

E hoʻouka i ka makemakika lauana o ka puunaue ana i ho'ākāka 'hereditary kāna moʻolelo i loko o ka waiʻauʻau'ōewe, aaiaoe? Io i ka manaʻo o ke kanaka heluna. He aha kāu kiʻina hana i ka hapanui i loko o ke koi ma ke kālā no 'epekema, e noiʻi i ia? He aha nō ka ekolu loa nui:

1. Heluna-ana helu hana.

2. kuauhau.

3. Twin.

Ma lalo o ka'ōewe auau ike genotypes o nā kānaka e noho ana i loko o ka ia wahi. Kēia paha ia i ka heluna kanaka o ka aina, he mau lāhui kanaka a kanaka pūʻulu e ola lawa ma ka hoʻokaʻawale, no ka laʻana, e noho ana o ke kauhale nalowale i loko o nā mauna o Afghanistan a me kaʻohana i loko o ka Amazon nani.

Ke genotypic characterization o ka heluna kānaka komo i ka 'ia paha o nā mea a pau nā'ōewe, a mawaho hoailona o kona kanaka. Heluna kanaka a me ka ana helu iaoia o ka noiʻi noi i ka hoʻopaʻa 'ana o nā sporadic abnormalities a me ka poe i loaa he okoa moʻokūʻauhauʻano o ka hōʻike' ia nei.

Ka mua pūʻulu ia lŘlŘ like me ka hopena o situational teratogens. ʻO nā pūʻulu ka loaʻa o ka nui papa inoa o nā anomalies, a i systematically kākau i loko o ka ua ohana, lāhui kanaka, aupuni 'ē aku, no ka manawa i lawa lōʻihi o ka manawa. No ka laʻana, polydactyly, makapo, hemophilia. E hoʻopaʻa haʻawina i keʻano papa hana o ka EYI o pathological hereditary kāna moʻolelo ka ke kaōhiʻana i kēia mau maʻi populjatsionno hoʻohana ana helu hana.

Makaʻu mea e pono ai i keʻano o ka maʻi me ka aaiaoe predisposition

Medicine multifactorial ano hoao (nā aaiaoe a? Aneie) pathologies i hoike mai ai ia lakou iho i loko o ka helu ana o kekahi mau kanaka hanauna. Aaiaoe Ka Ikepili o ka hypertension, 'ano aʻu mimikō, asthma, schizophrenia a me nā maʻi a me hereditary predisposition pono ai ke ao ana o na tausani o ko lākou kūʻauhau.

Ma kēlā me kēia hihia populjatsionno ana helu aaiaoe? Mea hiki ke huai ae i ke kiʻekiʻe o ke kanaka pūʻulu reactions o ke kanawai o? Aneie aʻe (ka pāhawewe microelement haku mele 'ana o ka wai inu, aniau) a me ka hooholo ana i na mea he nui nā'ōewe ka mea, ua ho'ākāka' ia hana.

Ua kanaka maʻi pili me aaiaoe heterogeneity o ka heluna kanaka

He aha hualoaʻa haawi i kekahi mau Ikepili o keʻano lāhui hui e noho ana i loko o ka hookahi? Aneie keia? Oko ma muli o ia mau populations like abiotic aʻe ka hooiaio o ko lākou aaiaoe heterogeneity.

Lapaʻau, ka 'ohana a me ka heluna ana helu iaoia no ke ao ana i kanaka aaiaoe? Ua hōʻike ana i ka nui o ka hoike ana o ka maʻi i loko o nāʻohana mea like me kona alapine (frequency) o ka hanana i loko o ka heluna kanaka. Ka mea, i hoʻohana 'ia i loko o ke ao o aaiaoe predisposition rumatika, allergies, e like me ka lapaʻau haʻawina o ka heluna kanaka loli ana ma multifactorial maʻi: mau sclerosis, Alzheimer ka, autism.

Makemakika hoaponoia o ka hoʻoilina

Ma mua o ka noonoo i ka mau aaiaoe? O kanaka populations, ua hoʻopaʻa haʻawina konaʻimi naʻauao? Aieao i hōʻike i loko o ka palapala o ke kānāwai makemakika. Kona Mānoa, he wahi like penei: ke alapine (frequency) o genotypes e like me kekahi o na nā'ōewe hiki ke ho omaulia ka hoʻohana i ka helu kaulike o ka huinahalike huina o nā helu. Naʻe, i kēia heluna kanaka pono auanei ko lakou nui, ka mea hiki ole e aaiaoe 'Aeʻa, a ma kona ano maoli koho koa, a penei kekahi ana spontaneously.

Ana ka heluna kanaka-ana helu hana no kanaka aaiaoe? A me ka hopena o ka lapaʻau loina këia, e mea hiki ke kilokilo i ke alapine (frequency) o phenotypic olelo o ka hemahema nā'ōewe, a me ka likelihood o ka ke keiki me ka pathology.

Pehea e hoʻomaulia i ka pahiki o ka maʻi

Eia he laʻana o ka'āina hoʻoili o ka phenylketonuria - aaiaoe maʻi, a ua nānā 'ana ma luna o ke kaʻana like' ia 'aʻe' nui'aminoʻakika phenylalanine. Ma populations oʻEulopa poe kanaka'āno'ē'ōewe hanana alapine (frequency). F mea 1: 10,000 nā mea maʻi i homozygous recessive genotype ff.

E ho ohana i ka uea 'heluna-ana helu iaoia, a me ka makemakika helu, he mea hiki, e hoʻonoho i ke alapine (frequency) o'āno'ē'ōewe. Ka mea, ua like ke 0,01. A laila, i ka pahiki o kāna moʻolelo ka hoikeia i loko o ka phenotype, he 0.99. Nolaila, na nā moku halihali mokulele o ka recessive'ōewe, me ka genotype Ff, hoolilo 0,02. Ia mea, i loko o kēia heluna kanaka o ka hola 2% o ka poʻe i noho i loko o lākou genotype recessive'ōewe no phenylketonuria.

E like me kakou e ike nei, o ka heluna kanaka-ana helu hana hoʻohana e hoʻomaulia i ke alapine (frequency) panmictic heluna o nā'ōewe kuleana no ka hōʻike o hereditary pathologies.

Hiʻona o kanaka populations

Ke evolution o kanaka noho maikai ana, ho okumu i ka liluwelo taxon, hiki e na poe like me ka ulu ana o kēlā me kēia ahupuaʻa kanaka, he wā lōʻihi o ka manawa e noho ana i loko o ka 'ia like ana. Ka mea, nā 'ano like climatogeographic kiko'î, he hookahiʻaoʻao o ka waha eʻai ai, a pau pathogens.

A pau i kēia ka pilina i ka ka hoʻohuiʻana i loko o ka'ōewe wai auau o populations o ka pūʻulu o maʻamau alleles a me nā hui ma na kahua o ka hoʻonaʻauao kakahiaka o anthropogenesis i ke kumu no ka hana ana i hereditaryʻano o ka oko a kūlohelohe koho.

I ka like o aaiaoe? O ka heluna kanaka a me ka ana helu ki ina hana like manawa? Mua o nā mea a pau, e ka kanawai ma luna o na kanaka genome puʻe wale hoʻokaʻawale o pili loa ka mare,? Aneie hoʻololi iho. Ka mea, alakai aku i ka'ōewe wai auau o ka manaʻo kanaka pauhia iho la ma ka'āno'ē nā'ōewe, a kena ae la i ka mea i hanaia o ka 'inikua-aaiaoe kūkā o ke akea pukapuka ke hoʻololi i ka hōʻike aaiaoe predisposition i ka hoike ana o ka maʻi likeʻole.
