Kupindura mibvunzo Pamusoro peMukomana Nomwanasikana Mapatya
Mubereki mumwe nomumwe wemapatya anotarisana mubvunzo wekuti "Mapatya ako akafanana kana ehama here?" Apo mapatya ako ari mukomana nemusikana vaviri, mhinduro yacho iri nyore, asi vanhu havazvioni nguva dzose. Vakawanda vanofunga kuti kufanana nemapatya kunoreva kuti mapatya anotarisa sei kwete maitiro avanoita sei. Tarisa hupenyu hwehupenyu hunotarisana nekubatana kwepabonde kunokwanisika nemapatya akafanana uye akabatana.
Ko Mukomana / Mhandara Mapatya Angafananidzwa Here?
Mhinduro shoma ndeye. Vanogara vari hama.
Mashoko aya akafanana uye ehama haarondedzere kuti mapatya anotaridzika sei, asi chaizvoizvo anoita sei. Zvakafanana ( monozygotic ) mapatya anogara achiita zvepabonde rimwe chete nokuti anogadzira kubva kune imwe yygote (yakakodzwa mazai) ane mamiriyoni evanhu (XY) kanakadzi (XX) zvepabonde. Nokudaro, mukomana / musikana mapatya anogara ari hama kana ( dizygotic ); vanogona kungogadzira kubva mairi mazai akaparadzana anogadzirwa nemaviri maviri evanhu. Vakadzi vemapatya vanogona kunge vari vaviri vaviri, vakomana vaviri, kana mumwe wega roga.
Izvi ndizvo zvinokonzerwa nekuita zvepabonde:
- Vasikana vaviri mapatya anogona kunge akafanana kana ehama (monozygotic kana dizygotic).
- Vakomana vaviri mapatya anogona kunge akafanana kana ehama (monozygotic kana dizygotic).
- Chikamu chemukomana / musikana mapatya anogona kungove hama (dizygotic). Mukomana / madiki mapatya haagoni kufanana (monozygotic).
Yakananga Twins
Mamwe mapatya anobva kune rimwe chete rinoberekwa rinoparadzaniswa kuva maviri.
Isati yaparadzana, inenge iri mukomana kana mukadzi. Mushure mokunge waparadzana, pane vaviri kana varume vaviri. Zvose zviri zviviri zveii inobereka inogadzirwa mumubereki uye imwe neimwe inobereka rimwe remapatya.
Mamwe mapatya ane mararamiro akafanana. Hapana chinokonzera chaicho chemonozygotic twinning yakagadzirirwa; hazvisi nhaka.
Monozygotic twins dzinomiririra nechetatu chemapatya ose. Zvinogona kutarisa zvakajeka, uye zvingave zvakaoma kuvatsanangurira .
Fraternal Twins
Vakaberekwa mapatya kune vanhu vaviri vakasiyana-siyana vanowanzoita mazai sezvavanouya kubva mazai maviri akaparadzana anogadzirwa nemurume wakasiyana. Iyo yakagadzirwa egg / sperm pamwe chete inogona kunge iri mukomana kana mukadzi. Mugumisiro wacho ndewe vaviri mababa mapatya, maviri mapatya emadzimai, kana mumwe mukomana nemukadzi mumwe chete.
Maitiro ekufananidza pakati pemapatya ehama ndiwo akafanana nevana vemunin'ina vaviri (anenge 50 muzana kana vane amai nebaba vakadaro). Vanogona kutarisa zvakafanana, kana kwete, sevamwe hanzvadzi nehanzvadzi. Vakadzi vemapatya ndiyo inonyanya kufanana nemapatya, anomiririra anenge maviri kubva kune zvitatu zvemawele ose.
Dizygotic twinning inogona kuva nhaka uye inomhanya mumhuri . Uyewo, mapatya akawanda uye akawanda anokonzerwa nekuberekwa kunobatsira kurapa, zvakadai semishonga kana nzira dzakadai se-in vitro fertilization, zvinonzi dizygotic pane monozygotic.
Kunze kwekuti Twin Sex Rule
Mutemo wega wega unowedzera, hongu. Muchiitiko ichi, ivo ndevamwe vasingadikanwi, uye hazvirevi kuti munhu akawandisa angambosangana nemapatya mumamiriro ezvinhu aya. Cherechedza kuti pane zvishoma zvataurwa zviitiko zve genetic mutation mu monozygotic male twins.
Nokuda kwechimwe chikonzero, mushure mokunge zygote inoparadzaniswa, rimwe twine rinorasikirwa neY chromosome uye rinokura sechikadzi. Iyo mapatya madzimai aizova neTterer syndrome, inoratidzirwa nekuita kwenguva pfupi uye kusimba kwekuvandudzwa kwemashizha. Izvo zvisingawanzoitiki; maitiro mashoma anodarika gumi akatsigirwa. Zvichienderana nematambudziko, zvakachengeteka kufunga kuti 99,9 muzana yevose mukomana / madiki mapatya ari hama.
Mapatya Anopararira
Nepo mapatya akafanana anobva kune imwechete yei inoberekwa uye anogovana DNA yakafanana, kune mikana yakawanda yemapatya ehama. Kunze kwekuva mbeu yemhando mbiri uye mazai eza, vanogona kunge vane mazita akasiyana-siyana emagetsi.
Heano maitiro akasiyana:
- Zvizvarwa zvemababa zvinogona kubudiswa apo mazai kubva kumukadzi mumwechete anogadzirwa nemurume kubva kune varume vaviri vakasiyana. Izvi zvinogona kuitika nekusagadzikana kwepfungwa uye ne-in vitro fertilization. Muchiitiko ichi, mapatya angave ari hafu-hama.
- Mukadzi anogona kutakura mapatya ane mimba mu-vitro nemazai emubatsiri, izvo zvinogona kubva kune vakadzi vaviri vakasiyana. Kana vakabatwa nemurume kubva kumunhu mumwe chete, mababa acho angave ari hafu-hama.
- Mazai evanhu vanobva kumadzimai maviri akasiyana aigona kubatanidzwa nemurume kubva kumurume maviri akasiyana. Muchiitiko ichi, mapatya angave asina DNA yakabatanidzwa kunze kwekuti chirume chemai nevanopa mazai vaiva nehukama. Vaizove vakafanana neshato-hama.
Shoko Rinobva Kunyanya
Iwe unogona kunge uchida kupindura mibvunzo yakafanana pamusoro pemapatya ako kakawanda. Uine zvishoma zvishoma pamusoro pemapatya, iwe uchakwanisa kungogunun'una uye kuzvitakura kana kujekesa ruzivo rwehupenyu hwemapatya.
