Wati wambonzwa mapatya akaiswa sa dizygotic kana multizygotic? Icho chinogona kutaridzika sechimwe rudzi rwechirwere chinoshamisa, asi dizygotic ndiyo chaiyo izwi rezvesayenzi kurondedzera chimwe chinhu chaunogona kunge wakambonzwa ... mapatya ehama . Zygosity inzira yekutsanangura kuti mapatya anotanga sei.
Dizygotic Twins Inoita sei?
Dizygotic twins inoumba kubva mazai maviri akasiyana akabatanidzwa nemaviri maviri evanhu.
(Di = 2, zygotic = zygote) Muzviitiko zvakawanda, mukadzi anongobudisa zhi rimwe chete, kana ovum, kubva kumapundu ake maawa panguva yehuvhu. Asi dzimwe nguva, nokuda kwezvikonzero zvakasiyana-siyana, mazai akawanda anobudiswa mumhepo. Kana kuita zvepabonde kana kuisa insemination zvichiitika uye mazai akabatanidzwa, zvizhinji zvinogona kuguma. Dizygotic twins dzinowanikwa apo mazai maviri anogadzirwa nemaviri emumvuri, kuisa mukati mechibereko, uye kukura kuva mabiko maviri. Izwi rokuti multizygotic rinogonawo kurondedzera mapatya maviri, pamwe chete nedzimwe dzakawanda, dzakadai sezvikamu zvitatu, zvitanhatu, quintuplets kana kupfuura. Iyo inongoparadzanisa zvipembenene zvakabva kune zygotes zvakasiyana, zvinopesana nemafuta e monozygotic anogadzirwa kubva kune imwe isina kubereka inoparadzaniswa.
Chii chinokonzera mapatya eDezygotic?
Kusiyana nemamonictic monozygotic, izvo zvisinganzwisisiki, kune zvikonzero zvakawanda zve dizygotic twinning. Pakupedzisira, ivo vose vanogona kuteverwa kune chimwe chinhu chinokonzera mukadzi kushaya hyperovulate, kana kusunungura kupfuura rimwe boka mairi.
Vamwe vakadzi vane shungu dzokuita kudaro nguva dzose, zvichida nekuda kwechimiro chemazwi . Vamwe vanogona kuita izvi nekuda kwehutachiona hunoitika. Zvichida vari kuyamwa , vari kutora mishonga yekuberekwa , kana kuti vakangorega kutora mapiritsi ekuberekwa. Vakadzi vakwegura vanogona kuratidzira sezvo miviri yavo inotungamirira kumwedzi.
Kune zvimwe zvakawanda zvinotsanangurwa, kusanganisira kudya, rudzi, kuneta uye mhuri yezvakaitika.
Unogona Sei Kuudza Kana Mapatya Ari Dizygotic?
Iwe unogona kufunga kuti iwe unogona kuziva kana mapatya ari dizygotic zvichienderana nekutarisa kwavanoita. Zvinowanzofungidzirwa kuti zvakafanana (monozygotic) mapatya anotarisa zvakafanana apo hama (dizygotic) mapatya hazviiti. Zvisinei, izvo hazvisi chokwadi zvachose, sezvo pane zvisizvo pamativi maviri. Monozygotic mamwe mapatya anotarisa zvakajeka akafanana, asi mamwe haataridzi zvakafanana. Saizvozvowo, dzimwe dizygotic twins dzine simba rakafanana, asi vamwe havasi.
Dizygotic twins dzinobatanidza maitiro ehumwechete ehumwe humwe humwe hama, sezvavanowana hafu yeDNA yavo kubva kuna amai vavo nehafu kubva kuna baba vavo. Kazhinji, ivo vanenge makumi mashanu munhu ane maitiro akafanana. Kungofanana nedzimwe mhuri dzinoratidza hutsika hunoonekwa, mamwe mazino ane mazamu anozove akafanana. Wati wambonzwa vanhu vachiti, "Anotarisa sezvakaita hanzvadzi yake panguva iyoyo!"? Dizygotic twins ndeyechizvarwa chakafanana nehanzvadzi; vanogona kufananidzwa kurutivi-ne-kurutivi panguva imwechete panguva, apo singleton vana vomumba vanofanira kuvimba nemifananidzo kana zvirangariro zvekufananidzwa kwezera rimwechete.
Kune dzimwe nzira dzekusimbisa kuti chokwadi kana mapatya ari dizygotic.
- Kana ivo vari mukomana nemusikana - ivo VAKAFANIRA dizygotic (nechisarudzo chisingawanzoitiki)
- Kana vane zviratidzo zvakasiyana-siyana zveropa - ivo VAKAFANIRA dizygotic
- Kana pane imwe placenta - ndeye PROBABLY NOT dizygotic
- Kana pane malascenta maviri - anogona KUVA dizygotic, asi anogona kunge ari monozygotic
- Kana pane monochorionic - havasi dizygotic
- Kana iine monoamniotic - iyo INOFANIRA HERE dizygotic
- Kana vakatarisa zvakafanana - VANOGONA kuva dizygotic
- Kana kuongorora kweDNA kuchiratidzira kusiyana kwezvikwangwani - ivo VANOFANIRA kuti dizygotic
- Kana kuongorora kweDNA kunoratidzika zvakakosha zvakakosha - havasi dizygotic
Dizygotic twins anogona kuva vakomana, vasikana kana mumwe wega roga.
Vose mukomana / madiki mapatya ane dizygotic mapatya, ane zvisizvo zvisingawanzoitiki. Izvo zvisingashamisi kuti munhu akawandisa haafaniri kuonana navo.
Zvingave zvichibvira kuziva kana mapatya ari dizygotic panguva yekuzvitakura, asi dzimwe nguva haigoni kuvimbiswa kusvikira vaberekwa. Vanhu vazhinji-kusanganisira vanachiremba-vanofungidzira kuti mapatya ari dizygotic kana ari muzvikwama zvakasiyana uye ane mapapiro maviri akasiyana, zvisinei, izvo hazvisi nguva dzose. Dzimwe nguva, kuburikidza ne ultrasound kana kumwe kuedzwa, zvinyorwa zvinogona kubatsira kuona zygosity, zvakadai sepabonde yakasiyana kana kuti neropa rakasiyana. Asi kazhinji, pakusina kwekusiyanisa kwakadaro, kuongororwa kweDNA ndiyo nzira yakarurama kwazvo yekuvimbisa kuti mapatya ane dizygotic.
