El vacheche ziso ruvara mushure mokunge achangoberekwa angave asina chokwadi. Vana vazhinji veCaucasian vanozvarwa vaine ruvara rwebhuruu, asi ine tsananguro, sezvo melamine iri chikamu che chinhu chikuru chekugadzira ruvara urwu. Kusvikira mukomana kana musikana asvika mwedzi 12 kana 18 yezera, ruvara rwemaziso harugoni kuzivikanwa.
Kuti uzive ruvara chairwo unogona kutevedzera mamwe nhungamiro yakavakirwa pa karukureta inofananidzira kururama muchikamu. Asi ichava fungidziro bedzi, sezvo zivo yakadaro ichigona kuwanwa kupfurikidza nokurega nguva ichipfuura. Haufaniri kuvimba naye ruvara rweziso kana azvarwa asi nekufamba kwemwedzi anenge achiratidza ruvara rwaachagara.
Unofanira kumirira kwenguva yakareba sei kuti uzive ruvara rweziso remwana?
Zvese zvinoenderana neiyo melamine, chinhu chiripo pakuzvarwa uye icho ichagadzirisa tonality yeganda, maziso uye kunyange bvudzi. Saka unofanira kumirira gore uye kunyange imwe nguva yakati wandei pkuziva data chaiyo. Pane zviitiko umo melamine inogona kuita kusvika pamakore matatu. Muzviitiko zvakawanda, ruvara rweziso rwatosviba nemwedzi mitanhatu kusvika misere yezera uye naizvozvo richava ruvara rwaanonamatira.
Ruvara rweziso runogona kuverengwa here?
Inogona kuverengwa, asi chete ichava data yakarurama inogona kukundikana. Iko hakuna kuverengera chaiko, sezvo kwave kune zvisingawanzo zviitiko apo vabereki vaive nemeso ebrown uye vaine mwana ane maziso ebhuruu. Kana kunyange vabereki vane maziso ebrown vane mwana ane maziso ebrown. Asi izvi zvinogona kuitika chete kana zvimwe vabereki vane recessive gene, sezvo paine hama ine jini iri uye rinoita kuti rigarwe nhaka kuvazukuru.
Kubva pano iwe unogona kugadzira chaiyo Calculator, asi sezvatakaongorora, zvichangove zvekupa fungidziro. Kana vabereki vaine maziso ebrown zvingava zvine musoro kuita vana vane maziso ebrown. Zvakafanana zvinoenda kuvabereki vane maziso ebhuruu sezvo vanogona kuva nevana vane maziso ebhuruu. Asi chii chinoitika kana vabereki vaine musiyano weruvara?
- Kana mumwe wevabereki ane maziso ebrown uye mamwe maziso ebhuruu, mukana mumwe chete 50% mukana kuva nemaziso eblue kana brown. Imwe yemikana inogona kunge iri yegirini maziso.
- Kana mumwe wevabereki aine maziso egirini uye mamwe mashava, mukana uchava 30% maziso egirini, mumwe mukana unoratidza a 50% brown uye 12% yebhuruu.
- Kana mumwe mubereki ane maziso ebhuruu uye imwe girini, tine mukana we 50% yebhuruu uye imwe 50% yegirini.
- For the maziso ebrown muvabereki vese kunewo chikamu chezana. Mukana unoratidza a 75% kuti mwana ane maziso ebrown, 18% girini uye 6% yebhuruu.
Zvikamu zvinoverengeka zvinofanirwa kuve nuanced. Iyi mhando yekarukureta inongova data yekupa chiratidzo chemavara, sezvo chake chiri dzidza mhoteredzo yemhuri kuti ienderane nemativi akasiyana-siyana. Kakawanda ruvara runogona kutipa zvinopfuura kumwe kushamisika, kunyanya kana vana vane maziso ebhuruu.
Ruvara rwebhuruu ruvara rwakanaka, asi izvo zvinoenderana nezvinoda. Tinofanira kuratidza yechipiri nuance, iyo brown ichagara ichinyanya kutonga kupfuura yebhuruu. Kuti upe iyo chaiyo uye yakachena ruvara, mavara maviri makuru anofanira kuenderana uye izvo zvinogona kukanganisa kugumisa bhuruu rechokwadi. Rudzi urwu runoda simba remakromosomes 15 ne19, sezvo iri ruvara rusina simba, mikana yacho inodzikiswa.
