Chiitiko chinoshamisa che mapatya magirazi Ichokwadi icho zvinoitika kashoma pakati pe25% yezviitiko. Izwi rokuti "girazi" rinoshandiswa kureva kuti vana vanozvarwa vakafanana zvachose, semadonhwe maviri emvura.
Ndivo vana vanozvarwa varipo mapatya akafanana, kureva kuti dzakasikwa mukati mechibereko nekuda kwekusangana kwezai nembeu imwe chete. Vanoumba zygote uye iyo inopatsanurwa kuita maembryo maviri. Kuti uwane rumwe ruzivo tichaongorora kuti ndeapi mamwe maitiro avanawo.
Mirror cufflinks yakaita sei?
Sezvatatoratidza, mapatya akafanana. Iwo akafanana kana monzygotic mapatya. Vane peculiarity, kuti ivo vakasikwa nekuda kwekusangana kwezai nembeu, uyezve, gadzira zygote uye inoparadzaniswa kuita mazai maviri. Panguva imwecheteyo vane humwe hunhu hukuru, mapatya aya anokura uye vanogovana placenta imwechete uye amniotic sac.
Sei vakasiyana nedzimwe mimba dzemapatya?
Pamuviri pemapatya anogona kusiyaniswa kubva kune imwe kuenda kune imwe panguva iyo zygote inogadzira kupatsanurwa kwayo. Pane nyaya dzakasiyana:
Mapatya asina kufanana kana dizygotic
Vanonzi mapatya. Izvi zvinokonzerwa nemazamu maviri mukati medumbu, asi munyaya iyi mukadzi anodzinga mazai maviri uye ose anosanganiswa nembeu mbiri dzakasiyana. Muchiitiko ichi tiri kutaura nezvevana vaviri vakakura muchibereko chimwe chete uye vasina kugovera amniotic sac, kana placenta, uye havana genetics yakafanana. Vaviri kubva pavatatu vane pamuviri pemhando iyi.
Mapatya akafanana kana monozygotic
Ndivo vakatotsanangurwa. Apa ndipo apo zai rinenge rasanganiswa uye apo zygote inotsemuka nepakati. Pakuparadzanisa, mazai maviri anogadzirwa ane genetic load yakafanana.
- Bichorial uye diamniotic. Zygote inopatsanurwa mazuva matatu mushure mekusangana. Muchiitiko ichi, "embryos" dzakaumbwa dzinowedzerwa ne placenta yavo uye inokura mune yavo amniotic sac.
- Monochorionic uye monoamniotic. Kuparadzaniswa kwezygote kunoitwa gare gare, pakati pezuva rechinomwe neregumi nematatu rekusangana. Pano ma embryos anogovana placenta imwechete uye amniotic sac imwechete. Apa ndipo panogona kugadzirwa mapatya egirazi, kunyangwe achigadzira hunhu hwekuparadzanisa pakati pezuva repfumbamwe neregumi nembiri mushure mekusangana. Muchiitiko ichi, kupatsanurwa kwe masero akafanana, rimwe kuruboshwe uye rimwe kurudyi.
Panguva ino inogona kunge iri nyaya ye Kutsakatika Twin, apo imwe yembeu inenge isati yapedza kukura uye inotorwa naamai, nebeche kana kunyange neimwe mukoma. Ichi chiitiko chinozivikanwa kana chiitiko che ultrasound chakaitwa mumwedzi wechitanhatu wekuzvitakura uye zvakaonekwa kuti kune maviri kana kupfuura embryos. Gare gare, mune imwe inotevera ultrasound, imwe yacho inonyangarika uye imwe inoramba ichikura pasina dambudziko.
Akasarudzika maitiro egirazi cufflinks
Vana ava vanocherechedzwa nehunhu hwavo hwese pavanozvarwa. Nhengo dzakakura mumiviri yavo dzinogona kusikwa nenzira yakasiyana. Mwoyo, chiropa uye spleen zvakaiswa kubva kune imwe kuenda kune imwe kumativi akatarisana emiviri yavo. ndiko kufona "situs inversus" uye zvinoitika kashoma, nyaya imwe chete mu10.000. Kunyangwe iyo girazi mhedzisiro inogona kugadzirwa ine isingakoshi maficha akadai sebvudzi, birthmarks kana moles.
Data yakatsanangurwa zvakare kwayakaonekwa kuti vanogona kuita zvinhu zvinodzosera kumashure, mumwe anogona kuva kuruboshwe-ruoko uye mumwe-ruoko rworudyi, vanotovata nenhendeshure. Maitiro avo akatombodzidzwa, uko munhu anoratidza imwe reverse psychology kune imwe.
Kazhinji kacho rudzi urwu rwemapatya runoongororwa nevabereki pachavo vanocherechedza mamwe maitiro atotsanangurwa. Zvinofanira kucherechedzwa kuti Aya marudzi epamuviri haawanzoitiki, asi haagoneki. Muchiitiko ichi, iwe unoziva nezvenyaya.
