Kodi Mwana Wanga Adzakhala Ndi Mtundu Wotani? - Thanzi

Zamkati

Kuyambira tsiku lomwe mudazindikira kuti mumayembekezera, mwina mwakhala mukulota za momwe mwana wanu angawonekere. Adzakhala ndi maso anu? Mapini a mnzanu?

Nthawi yokha ndi yomwe inganene. Ndi mtundu wa tsitsi, sayansi siyowongoka kwenikweni.

Nazi zina zokhudzana ndi chibadwa choyambirira ndi zina zomwe zimatsimikizira ngati mwana wanu adzakhala blonde, brunette, redhead, kapena mthunzi wina pakati.

Mtundu wa Tsitsi Ukatsimikizika

Nayi mafunso ofulumira a pop. Zoona kapena zabodza: ​​Mtundu wa tsitsi la mwana wanu wakhazikitsidwa kuyambira pomwe mayi amatenga pakati.

Yankho: Zowona!

Umuna ukakumana ndi dzira ndikukula kukhala zygote, limapeza ma chromosomes 46. Ndiwo 23 ochokera kwa mayi ndi bambo onse. Makhalidwe onse obadwa ndi mwana wanu - utoto wa tsitsi, mtundu wa diso, kugonana, ndi zina zambiri - atsekeredwa kale kale koyambirira.


Chosangalatsanso ndichakuti mtundu uliwonse wama chromosomes omwe makolo amapatsira ana awo ndiosiyana kotheratu. Ana ena amaoneka ngati amayi awo, pomwe ena amafanana ndi abambo awo. Ena adzawoneka ngati osakanikirana, potenga mitundu ingapo yama chromosomes.

Chibadwa 101

Kodi majini amalumikizana bwanji kuti apange utoto wa tsitsi? Chibadwa chilichonse cha mwana wanu chimapangidwa ndi ma alleles. Mutha kukumbukira mawu oti "opambana" ndi "owonjezera" kuchokera mkalasi yasayansi yasekondale. Ma alleles otchuka amalumikizidwa ndi tsitsi lakuda, pomwe ma alleles owonjezera amalumikizidwa ndi mithunzi yoyera.

Pamene majini amakumana, mawu omwe amadza chifukwa chake ndi phenotype yapadera ya mwana wanu, kapena mawonekedwe amthupi. Anthu amaganiza kuti ngati kholo limodzi lili ndi tsitsi lalitali pomwe winayo ali ndi tsitsi lofiirira, mwachitsanzo, owoneka mopyapyala (blonde) atayika ndipo wamkulu (wa bulauni) apambana.

Sayansi ndiyomveka, koma malinga ndi Tech Museum of Innovation, zambiri zomwe timadziwa za utoto wa tsitsi zikadali mgululi.


Likukhalira, pali mitundu yosiyanasiyana ya bulauni. Brown-ebony ili pafupifupi yakuda. Maamondi a Brown ali kwinakwake pakati. Brown-vanila kwenikweni ndi blonde. Zambiri zomwe mungawerenge zokhudzana ndi chibadwa zimapereka utoto wa tsitsi kukhala wopambana kapena wopitilira muyeso. Koma sizophweka.

Popeza ma alleles angapo akusewera, pali kuthekera kokwanira kwa utoto wa tsitsi.

Mitundu ya nkhumba

Zingati komanso mtundu wanji wa pigment womwe uli mu tsitsi la munthu komanso momwe amagawidwira umathandizira kupanga mthunzi wonse.

Chosangalatsa ndichakuti kuchuluka kwa utoto wa tsitsi la munthu, kachulukidwe kake, ndikugawa kwake kumatha kusintha ndikusintha pakapita nthawi.

Pali mitundu iwiri yoyera yomwe imapezeka mu tsitsi la munthu:

  • Eumelanin ndi amene amachititsa matani abulauni / akuda.
  • Pheomelanin imayambitsa matani ofiira.

Tsitsi la Ana vs. Tsitsi Lalikulu

Ngati mwajambula zithunzi zanu zakale za ana, mwina mwazindikira kuti mudali ndi tsitsi lowala kapena lakuda ngati khanda. Zitha kukhala kuti zasintha muunyamata wanu komanso zaka zakusukulu, nanunso. Izi zimabwereranso ku mtundu watsitsi.


Kafukufuku wofalitsidwa ku Forensic Science Communications adalemba utoto wa ana 232 azungu, apakatikati aku Europe ku Prague. Adawulula kuti ana ambiri, anyamata ndi atsikana, anali ndi tsitsi lakuda mchaka choyamba cha moyo wawo. Kuyambira miyezi 9 mpaka zaka 2 1/2, utoto umachepa. Pambuyo pazaka zitatu, utoto wa tsitsi udayamba kukhala wakuda pang'onopang'ono mpaka zaka 5.

Izi zimangotanthauza kuti tsitsi la mwana wanu limatha kusintha mawonekedwe kangapo atabadwa asanakhazikike pamtundu wokhazikika.

Chialubino

Ana obadwa alubino sangakhale ndi khungu kapena khungu lawo, kapena khungu lawo. Matendawa amayamba chifukwa cha kusintha kwa majini. Pali mitundu yambiri ya maalubino yomwe imakhudza anthu munjira zosiyanasiyana. Ambiri amabadwa ndi tsitsi loyera kapena lowala, koma mitundu yambiri ndiyothekanso.

Vutoli limatha kuyambitsa mavuto amaso ndi kuzindikira dzuwa. Ngakhale ana ena amabadwa ndi tsitsi lowoneka bwino kwambiri, ana omwe ali ndi maalubino nthawi zambiri amakhala ndi eyelashes oyera ndi nsidze.

Chialubino ndi mkhalidwe wobadwa nawo womwe umachitika makolo onse awiri atadutsa. Ngati mukudandaula za vutoli, mungafune kulankhula ndi dokotala wanu kapena mlangizi wa majini. Mutha kugawana nawo mbiri yakuchipatala ya banja lanu ndikufunsanso mafunso ena aliwonse okhudzana ndi matendawa.

Chotengera

Chifukwa chake, mwana wanu adzakhala ndi tsitsi lotani? Yankho la funso ili silophweka. Monga zikhalidwe zonse zakuthupi, mtundu wa tsitsi la mwana wanu wakhazikika kale ndikulembedwera mu DNA yawo. Koma zimatenga nthawi kuti mukhale mthunzi weniweni womwe udzakhale.
