Kusunungura maawa anopfuura mwedzi pamwedzi inonzi genetic
Vanhu vane ruzivo rwakawanda nezvemhuri kana mazita ekugadzirisa mazai semapatya semapatya chinhu chinonakidza.
Kana iwe unenge uchifungidzira kuti genetic link, iwe uri chikamu chakanaka, asi hukama huri hwakaoma. Kune rimwe, mazamu anogona kuita nharo mukana wako wekuva nemapatya ehama (anonzi dizygotic twins) asi kwete maana maviri akafanana (monozygotic twins). Chechipiri, zvakakosha kunzwisisa kuti pangava nezvimwe zvinhu kunze kwemagetsi zvinowedzera mukana wevakadzi wekuva nemapatya.
Pane "Twin Gene" Here?
Maererano nekutsvakurudza kwemafuro, mukana wekuva nemapatya emukomana inenge kakapetwa kaviri kune vakadzi vane amai kana hanzvadzi vane mababa mapatya. Iyi yakawedzerwa mukana inokonzerwa nejeni rinokurudzira kuderedza-dzimwe nguva rinonzi "jini remaviri."
Kunyanya kufungidzira ndiko kuedza kusunungura maawa anopfuura maawa panguva yekuvhima, izvo zvinowedzera mukana wekutora dizygotic (kana mukoma) mapatya. Saka, mumhuri umo vakadzi vane tsika yokurwara, genetics inogona kutsanangura zvakakwana kuwedzera kwemababa ehama .
Zvisinei, sezvo vakadzi chete vanovhura, kuwirirana kunoshanda chete kumativi edzimai emhuri. Apo vanhu vanogona kutakura jenji uye vanoipfuudza kuvanasikana vavo, nhoroondo yemhuri yemapatya haina kuita kuti vave zvakare zvakare kuti vave nemapatya pachavo. Asi, kana baba vachipfuura "mazaini mapatya" kumwanasikana wavo, iye zvino angave akave nemikana yakakwirira kudarika yekugara kune mababa mapatya.
Unoita Mapatya Enda Kumarudzi Here?
Kana baba vako vaiva mapatya asi iwe usiri iwe, iwe unowanzova nemapatya here? Izvozvo zvinowanzosaziva kuti mababa anosvetuka chizvarwa mumhuri. Icho zvachose chisina uchapupu, kunze kwezvakaitika, kuti mapatya anowanzoitika kune dzimwe dzose chizvarwa. Zvisinei, kana iwe uchitarisa simba rekuberekwa kwemazamu, izvi zvinogona kuonekwa mumhuri zvichienderana nekuti vana vavo vaiva vanakomana kana vanasikana.
- Chizvarwa 1: Ambuya
Ambuya vane geni rekunyengedza. Iye naShekuru vane hama dzepatya twese, Rob naBob. - Chizvarwa 2: Rob & Bob
Kunyange zvazvo vanakomana vaAgogo vanga kutakura geni rekutsvaira, havaiti. Havazovi nemapatya (kunze kwezvimwe zvinhu). Zvisinei, mumwe nomumwe ane mwanasikana. - Chizvarwa 3: Molly & Polly
Molly naPolly, vanun'una, vanowana nhaka yehupenyu hwekutsvaira kubva kumadzibaba avo. Mumwe nomumwe ane mapepa maviri.
Iwe unogona kuona kuti muenzaniso uyu unoita kuti zvionekwe sei kuti mapatya anosvetuka chizvarwa mumhuri. Muenzaniso wacho unofungidzirwa kana muzukuru weiyo hyperovulation gene ari murume kana mukadzi.
Pane Kubatanidza Pakati Pakafanana Maviri neGenetics?
Kunyange zvazvo dzidziso uye tsvakurudzo dzakawanda, hakuna hutano hwakagadziriswa pakati pe genetics uye monozygotic (yakafanana) twinning. Masayendisiti haana kunyatsojekesa chikonzero chakajeka chemonozygotic twinning, iyo inowanikwa apo mazai anogadzirwa anowedzera ndokutanga kuva maviri (kana kupfuura) embryos.
Panguva ino, monozygotic twinning inoratidzika sechiitiko chisina kuitika, saka vabereki vose vane mukana wakaenzana wekubata mapatya akafanana.
Kana Ndiine Maviri Mumhuri Yangu, Ndichava Nemapatya?
Hapana nzira yekufanotaura kuti ndiani ndiani uye ndiani asingazovi nemapatya.
Izvozvo zvichiti, kana uchitora mikana yako, funga izvi:
Ndeapi mapatya ari mumhuri? Yeuka, monozygotic (yakafanana) mapatya haashamisi mumhuri-inongoerekana yavapo. Iwe unogona kunge usingazivi kana zvikuru-zvikuru vako zvaive zvakafanana kana kwete uye kazhinji hapana nzira yekuziva zvechokwadi pasina DNA kuongororwa. Izvo zvichitaurirwa, mapatya anowirirana zvakafanana zvakanyanya kuve akaenzana kudarika ukama. Uyewo, rangarira kuti mukomana / madiki mapatya anogara ari hama (dizygotic).
Ima mapatya ari mugumisiro wekubatsira kubereka here? Mumakore gumi apfuura, nhamba huru yemapatya uye yakawanda inoberekwa inonzi inobereka mishonga inobereka kusanganisira zvinodhaka uye in vitro fertilization.
Semuenzaniso, kuberekwa kwechirwere chechirwere chinonzi Clomid chinogona kukurudzira kusunungurwa kwamaawa anopfuura maawa panguva yekuvhenekera. Izvi zvinogona kutungamirira kumapatya emadzimai kana mazai maviri akabatanidzwa.
Ndeupi rutivi rwemhuri rwaiva nemapatya? Kana mapatya aripo kumativi omurume wako / shamwari, haingakanganisi mikana yako yekuve nemapatya . Yeuka, ruzivo rwehuwandu hwemhuka hunongova chikonzero cheamai. Kana amai vako (kana mbuya vako kana vanamume) vaiva kana vaine mapatya ehama, iwe ungave uine jeni. Asi nhoroondo yemhuri yemurume wako haitombotauri pamusoro pevana vako, kunze kwekuda kweramangwana iwe unogona kunge una vana vazukuru-kana iwe une mwanasikana anowana nhaka yehuwandu hwemajini.
Shoko Rinobva Kunyanya
Yeuka, nhoroondo yemhuri yemapatya ndiyo imwe chete yezvikonzero zvakawanda zvinokanganisa vana vakaberekerwa . Nguva yemadzimai, rudzi, kuyerwa, kudya, uye nhoroondo yekubereka zvose zvinobatsira pakuita twinning uye inogona kuva nemasimba anopfuura simba remhuri.
