Asayansi apeza kuti mwana amatengera nzeru za ndani.
- Ndiwe anzeru ndani? - abwenzi amafunsa mwana wanga mwachikondi pamene iye, pa zisanu ndi theka, amawauza tebulo kuchulukitsa ndi zisanu ndi zinayi.
Inde, panthawi imeneyi ine ndi mwamuna wanga tikumwetulira mosangalala. Koma tsopano ndadziwa choonadi. Koma ine sindidzamuuza mwamuna wake. Ndikukuuzani. Mwana amatengera nzeru kuchokera kwa mayi yekha. Bambo ali ndi udindo pa makhalidwe ena - khalidwe lalikulu, mwachitsanzo. Zatsimikiziridwa ndi Asayansi!
Maphunzirowa adachitidwa ndi akatswiri ochokera ku Germany (University of Ulm) ndi Scotland (Social Council for Medical Research and Public Health Glasgow). Ndipo kuti mumvetsetse malingaliro awo, muyenera kukumbukira gawo la majini kuchokera ku biology yakusukulu.
Choncho, tikudziwa kuti khalidwe, maonekedwe, komanso maganizo a mwana, zimapanga majini a makolo ake. Ndipo X chromosome imayang'anira jini yanzeru.
“Akazi ali ndi ma chromosome aŵiri a X, ndiko kuti, ali ndi kuthekera koŵirikiza kaŵiri kwa kupatsira khanda za nzeru zawo,” asayansi akutsimikizira motero. - Pa nthawi imodzimodziyo, ngati majini a "luntha" amafalitsidwa nthawi imodzi kuchokera kwa makolo onse awiri, ndiye kuti abambo amawongolera. Jini la mayi ndilokha limagwira ntchito.
Koma tiyeni tisiye chibadwa. Palinso umboni winanso. Mwachitsanzo, anthu a ku Scotland anachita kafukufuku wamkulu. Kuyambira m’chaka cha 1994, nthaŵi zonse afunsa achinyamata 12 azaka zapakati pa 686 ndi 14. Zinthu zambiri zinaganiziridwa: kuyambira khungu mpaka maphunziro. Ndipo anapeza kuti njira yotsimikizirika yodziŵira mmene IQ ya mwana idzakhala ndiyo kuyesa luntha la amayi awo.
“M’chenicheni, izo zimasiyana ndi iwo kokha ndi avareji ya mfundo 15,” akulongosola mwachidule asayansiwo.
Nali kafukufuku wina, nthawi ino wochokera ku Minnesota. Ndani amakhala ndi nthawi yochuluka ndi mwanayo? Ndani amamuyimbira nyimbo, kusewera naye masewera ophunzitsa, kumuphunzitsa zinthu zosiyanasiyana? Ndizofanana.
Akatswiri amaumirira kuti: kukhudzidwa kwamtima kwa mwana ndi mayi kumakhudzananso mwachindunji ndi nzeru. Komanso, ana oterowo amalimbikira kwambiri kuthetsa mavuto ndipo amayankha mosavuta akalephera.
Kawirikawiri, mosasamala kanthu kuti akatswiri a majini ndi akatswiri a chikhalidwe cha anthu anayesa bwanji, sanapeze "zotsatira" za munthu m'madera a ubongo omwe ali ndi nzeru, kulingalira, chinenero ndi kukonzekera. Koma akufulumira kutsimikizira abambo: udindo wawo ndiwofunikanso kwambiri. Koma m'madera ena. Amuna majini zimakhudza limbic dongosolo, amene, malinga ndi asayansi, kwenikweni udindo kupulumuka: amalamulira kupuma, chimbudzi. Amalamuliranso malingaliro, njala, nkhanza ndi machitidwe ogonana.
Kawirikawiri, kukula kwa nzeru kumadalira cholowa ndi 40-60 peresenti. Ndiyeno - chikoka cha chilengedwe, makhalidwe munthu ndi analeredwa. Choncho samalirani ana anu ndipo ena onse adzatsatira.
