Chii chinonzi monozygotic twins? Iwe unogona kunge wakanzwa izwi iri rinoshandiswa kurondedzera mapatya, asi hauzive kuti rinorevei. Izwi rinowanzozivikanwa uye rinowanzoshandiswa pamhando iyi yemapatya " zvakafanana " mapatya. Nemhaka yenzira iyo monozygotic twins dzinoumba, dzinowanzoita zvakafanana uye dzine zvimwe zvakafanana. Ndizvo nokuti monozygotic mapatya anowanikwa kubva kune imwe isina kubereka inoparadzanisa kuumba mazai maviri anoumba kuva vana vaviri.
Nemhaka yokuti vanhu vaviri vanobva kune imwe chete, vanogovana zvakafanana mazita evanhu uye vanogona kuratidza kufanana kunoshamisa. Nokudaro, vanoonekwa se "zvakafanana."
Izwi rokuti monozygotic rinotsanangurwa zviri nani kune rudzi urwu rwemapatya panzvimbo pekuvatsanangurira zvakafanana. Kunyange zvazvo monozygotic mapatya akafanana zvikuru nenzira dzakawanda, haasi clones. Kunyange zvazvo vanogona kutarisa zvakafanana, vane unhu hwakafanana, uye vanakidzwa nezvinhu zvakafanana, ivo vaviri vanhu vakasiyana. Izwi rokuti monozygotic rinonyatsotsanangura mavambo avo. Mono = imwe, zygote = yai yakabereka. Idzo mapatya akazovapo kubva kune imwe isina kubereka.
Monozygotic Twins Anoitwa Sei?
Ngatitarisei kuti izvi zvinoitika sei. Somugumisiro wepabonde kana in vitro, unhu humwe hunoita huri rimwechete (oocyte). Sezvo iyoi yakabereka (zygote) inofamba ichienda kuchibereko, masero anoparadzanisa ndokubatanidza kuva blastocyst.
Uye mune monozygotic mapatya, nokuda kwezvikonzero izvo zvisinganzwisisi zvachose, blastocyst inoparadzaniswa zvikamu zviviri zvakasiyana zvachose uye inoita seviri yakasiyana embryos. Izvozvo zvinoguma nei? Twins!
Hapana sarudzo yakagamuchirwa nesayenzi yekuti sei ichi chinoitika kana chinokonzera. Monozygotic twins inowanzoramba isina chakavanzika.
Havana kutungamirirwa nehumwe humwe humwe hunoita kuti twinning, zvakadai semhuri yemhuri , makore ekuberekwa, kana kurapa kwekubereka. Mutengo wemonozygotic twinning unoramba wakafanana mumarudzi ose uye vanhu vakawanda.
Monozygotic twins inomiririra shoma shoma yemapatya. IUnited States yakanyora inenge 132,000 mapatya maviri muna 2013, inomiririra 33.7 kubva pamakabhiyoni ose ekuzvarwa. Asi chete 3 kana 4 kubva pa1 000 ndivo monozygotic mapatya.
Unogona Sei Kuudza Kana Mapatya ari Monozygotic?
Dzimwe nguva, zvinokwanisika kusarudza zygosity panguva yekuzvitakura . Zvichienderana nezvenguva yekuparadzana, mamwe mapapiro emonozygotic anokura neavo, akagovera placenta uye akabatanidzwa mune imwe chorion kana amnion. Zviratidzo izvi, zvinoratidzwa pa ultrasound, zvinogona kuziva monozygotic mapatya. Asi kazhinji, hazvizivikanwi. Kunyangwe mushure mokuberekwa, zvingasave zvisingakwanisi kugadzira zygosity pasina kuvimbiswa neDNA test.
Heano dzimwe nzira dzaunogona kuziva kana mapatya ari monozygotic:
- Kana ivo vari mukomana nemusikana - ivo vangave vasina Monozygotic
- Kana ivo vane marudzi akasiyana-siyana - haasi Monozygotic
- Kana pane imwe placenta - ndeye PROBABLY monozygotic
- Kana pane malascenta maviri - anogona kunge ari POSSIBLY monozygotic
- Kana pane monochorionic - inenge inenge yakakodzera Monozygotic
- Kana ivo vari monoamniotic - ivo VANOFANIRA monozygotic
- Kana vakatarisa zvakafanana - ndivo POSSIBLY monozygotic
- Kana kuongorora kweDNA kunoratidzira zviratidzo zvakabatana - zvinonzi ZVAKANAKA monozygotic
- Kana kuongorora kweDNA kuchiratidza kusiyana kwezviratidzo - havasi MONI monozygoticMonozygotic mapatya anogara ari mumwechete wepabonde. Dzinotangira kune imwe yygote, yeuka? Apo inoparadzaniswa, ma-chromosomes ega ega aripo mumabiri maviri. Zvechokwadi, pane zvakajairika zvikuru
Monozygotic twins anogara ari mumwechete wepabonde. Dzinotangira kune imwe yygote, yeuka?
Apo inoparadzaniswa, ma-chromosomes ega ega aripo mumabiri maviri. Zvechokwadi, kune zvidimbu zvisingawanzoitiki. Izvo zvisingashamisi, kuti hazviiti kuti iwe uchazombosangana navo. Saka, zvakachengeteka kufungidzira kuti rimwe ramapatya ari mukomana nemusikana haasi monozygotic. Monozygotic twins inogona kuva vasikana vaviri kana vakomana vaviri.
Saizvozvowo, monozygotic twins dzinoshandisa imwe DNA yavo yose. Maitiro avo ekufananidza anotsanangura kuti nei vachiwanzoita sevanonyanya kufanana uye kazhinji vane zvido zvakafanana uye maitiro. Dhiyabhorosi yeDNA inofananidza mazita ezve genetic uye inogona kusimbisa kuti mapatya ari monozygotic. Zvisinei, mazamu haatauri zvinhu zvose nezvemunhu, uye kune nzira dzakawanda dzinofanana nemapatya dzakasiyana kubva kune mumwe. Maitiro ezvakatipoteredza, epigenetic divergences, uye zviitiko zvehupenyu zvinogadzirisa zvakasiyana zvinoita kuti vave vanhu vakasiyana.
