Izobukeka kanjani ingane yakho? Lo kungaba ngumbuzo wokuqala oza engqondweni uma ukukhulelwa kwakho sekuqinisekisiwe. Kukhona, ngemuva kwakho konke, izici eziningi zofuzo ongacabanga ngazo.

Kusukela ezinweleni, amehlo, nezici zomzimba kuya ezicini zomqondo nokuningi, ukubukeka nobuntu bengane yakho kuzohlala kuyimfihlakalo njengoba bekhula esibelethweni.

Yini ngemuva kokubukeka kwengane yakho?

Ingxenye yamaseli womuntu ebhekele indlela izici ezahlukahlukene ezizuzwe ngayo ibizwa nge-DNA. Kungukuqoqwa kwazo zonke izakhi zofuzo ezixubekayo lapho kukhulelwa umntwana omusha.

I-DNA yomuntu (cabanga ngayo njengohlobo oluthile lwemali yezakhi zofuzo) ihlelwe yaba yimimo okungenzeka wake wayibona emidwebeni nasezithombeni ezibizwa ngama-chromosomes. Zifana nohlamvu X oluthambile. Umuntu ngamunye unama-46 esewonke.

Ingane yakho izothola ama-chromosomes angama-46, angama-23 kumzali ngamunye. Ipheya elilodwa ngama-chromosomes ezocansi, aziwa njenge-X no-Y. Izonquma ubulili bengane yakho.

Ukuhlanganiswa kwezakhi zofuzo ezikhona kuma-chromosomes, cishe angama-30,000 azo, ngokwesibonelo, kuzonquma:

• umbala wamehlo engane yakho
• izinwele
• ukuma komzimba
• ubukhona noma ukungabi bikho kwamadimples
• izwi elikhulu lokucula

Uqinisile ngokucabanga ukuthi izakhi zofuzo ezingama-30,000 noma ngaphezulu ziyizinto eziningi zokuxuba nokufanisa. Ukuhlanganiswa okungenakubalwa kungenzeka, yingakho kungelula ngaso sonke isikhathi ukubikezela kahle ukuthi ingane yakho izobukeka kanjani.

Noma kunjalo, ngenxa yokuthi izakhi zofuzo zisebenza kanjani, kungenzeka ukwenza izibikezelo ezinembe ngandlela-thile. Kungumdlalo omnandi wokudlala ngenkathi ulindele.

Isebenza kanjani i-genetics?

Izinwele nombala wamehlo ngamunye unqunywa iqoqo lezakhi zofuzo ezilawula ukuhlanganiswa kombala. Lokhu kungenza izinwele, amehlo, nesikhumba zikhanye noma zibe mnyama.

Qala ngama-albhamu wezithombe zomndeni kusuka kubo bobabili abazali. Lapho ungabona ukuthi imuphi umbala wezinwele ovelele, noma ngabe impandla yeqa isizukulwane, futhi uma amehlo aluhlaza okwesibhakabhaka avela ngezikhathi ezithile kubazali abanamehlo ansundu.

Ngenkathi umphumela wokugcina ungenakwenzeka ukuqagela ngokunembile, nalu olunye usizo lokuqonda ukuthi ufuzo lusebenza kanjani.

Imaphi amehlo ombala ingane yakho ezoba nawo?

Ngokuvamile kunezinguqulo ezimbili zofuzo ngalunye: eyodwa eqinile (kwizakhi zofuzo ibizwa ngokuthi iyinhloko) futhi ebuthakathaka (ebizwa ngokuthi i-recessive). Ingane yakho izuza izakhi zofuzo kubazali bobabili. Ezinye zazo zizoba namandla futhi ezinye zibe ngokweqile. Kusebenza kanjani lokho kumbala wamehlo?

Isibonelo, uma unamehlo ansundu futhi ikakhulukazi wonke umuntu emndenini wakho unamehlo ansundu, lokho kukhomba enguqulweni eqinile noma evelele yohlobo lombala wamehlo ansundu noma isethi yezakhi zofuzo. Ake sithi omunye umzali unamehlo aluhlaza okwesibhakabhaka nomndeni wakhe onabile, nawo. Ingane yakho kungenzeka ibe namehlo ansundu ngoba lowo mbala uvame ukubusa.

Izakhi zofuzo eziluhlaza okwesibhakabhaka ngeke zilahleke, noma kunjalo. Bangakhombisa umgwaqo kubazukulu bakho, uma kwenzeka kuba nenhlanganisela ethile yezakhi zofuzo ezivela kubazali.

Ngendlela efanayo, uma nobabili nomlingani wakho ninamehlo ansundu kodwa nibe nokhokho abanamehlo aluhlaza okwesibhakabhaka (hlola i-albhamu yomndeni!), Ingane yakho ingahle ibe namehlo aluhlaza okwesibhakabhaka ngoba ngamunye wenu unezakhi zofuzo eziluhlaza oziphatha kwi-DNA yakho .

Yiziphi izinwele zombala ingane yakho ezoba nazo?

Izakhi zofuzo ezinamandla noma ezivelele zinquma umbala wezinwele wengane yakho, futhi. Kunezinhlobo ezimbili ze-melanin pigment ezinweleni okuthi, kuya ngokuthi iziphi izakhi zofuzo ezinamandla, zixubeke futhi zinqume umbala wezikhiye zengane yakho.

Njengoba ingane yakho ikhula, ungaqaphela ukuthi izinwele zazo ziba mnyama. Lokho kuvamile. Ihlobene nokunye kokukhiqizwa kombala kunciphisa ijubane.

Ngokuvamile, uma unezinwele ezimnyama, kungahle kube nohlobo lwe-blond noma mnyama oluthwele. Ngakho-ke uma umlingani wakho enenhlanganisela efanayo, abantu ababili abanezinwele ezimnyama bangaba nengane emhlophe noma ebomvu. Lokho konke kuyingxenye yokudlala kofuzo okujwayelekile.

Lapho uzama ukubikezela izici ezinjengezinwele noma amehlo, kungenzeka ukuthi ubheke namathoni esikhumba. Kwesinye isikhathi umuntu uba nezinwele ezimnyama nesikhumba esikhanyayo, okuyinkomba yokuthi kunethuba lokuba nomntwana ozodlala izinwele ezinombala okhanyayo.

Ngabe ingane yakho izobukeka ifana nobaba kunomama?

Ukubheka ingane esanda kuzalwa ukubona ukuthi ibukeka kanjani kaningi kunabantu abakhomba ubaba. Ngabe lokho kusho ukuthi izingane zifana kakhulu nobaba bazo kunonina? Akunjalo Empeleni.

Incazelo ezwakalayo kunazo zonke, abacwaningi bathola, ukuthi emakhulwini eminyaka adlule, ukufana kukababa nomntwana kwakusho ukuthi ubaba omusha uzoba nesikhuthazo esikhulu sokuhlinzekela umama nengane.

I-Biology kanye ne-genetics akusebenzi kahle nemibono yokuzithoba, noma kunjalo. Ngenhlanhla, abantu manje sebazi ukuthi izingane zingabukeka njengabazali. Kepha imvamisa, bayinhlanganisela eyinkimbinkimbi yalokhu okubili, kanye nezici ezithile zomndeni ezidlulisiwe.

Futhi, uma unikezwe ukuthi izici eziningi zeqa isizukulwane noma ezimbili, kungenzeka ukuthi ubona ugogo wakho omkhulu enganeni yakho kunalokho obekulindele. Ukuba nezithombe ezisebenziseka kalula kwenza kube lula ukuletha ukuqagela kwakho eduze kwangempela.

Into eyodwa okufanele uyazi ukuthi kunezinganekwane eziningi laphaya mayelana nendlela izici ezahlukahlukene ezizuzwa ngayo. Izakhi zofuzo zizenzela okwazo, ngakho-ke ezinye izinhlanganisela zinganikeza umphumela ongalindelekile.

Isibonelo, uma wena nomlingani wakho nobabili nibadala, kunamathuba amaningi okuthi ingane yakho ikhule ibe ngumuntu omude. Umehluko wokuphakama uzobeka ingane yakho phakathi kwebanga lokuphakama. Ubulili bufaka isandla ekuphakameni, futhi.

Ngezansi

Izobukeka kanjani ingane yakho? Kungumdlalo wokuqagela onabo bonke abazali ezinzwaneni zabo kuze kufike usuku olukhulu futhi babheke inqwaba yenjabulo yabo.

Akunandaba noma ngabe ubukulindele ini enganeni yakho, uma isizelwe uzozithola uhlanya othandweni, umbala wamehlo nowezinwele yize kunjalo. Jabulela ukwehluka kwengane yakho, kokubili ngokomzimba nangokwengqondo. Kujabulele ukuqagela ukuthi izakhi zofuzo ziwakhe kanjani umndeni wakho!
