Yintoni inhlanganisela yemfuza, kunzima kakhulu ukuthetha. Abantu bazama ukuqikelela, kodwa imvelo kunye nezofuzo zenza nje umsebenzi wazo. Kwakhelwe ukuhlanganiswa kweempawu zobomi zomntwana, ezinamandla (eziphambili) kunye nezifo zegesi ezibuthathaka (ezithintekayo) zithatha inxaxheba. Iimpawu ezinamandla zofuzo ziquka iinwele ezimnyama, kwakunye neentambo ezibukhali; Amehlo amdaka, eluhlaza okanye eluhlaza obomvu; isikhumba somnyama; ukuguqa emadodeni; i-Rh inqobo; Ii-II, III kunye ne-IV kunye nezinye iimpawu. Ziquka neempumlo ezinkulu, impumlo kunye neempundu, izindlebe ezinkulu, imilomo ekhuphayo, iphambili ephezulu, iqhosha elinamandla kunye nezinye iimpawu ezibonakalayo "ezivelele". Iimpawu zobuthakathaka ezibuthathaka ziquka iinwele ezimvu, ezikhanyayo, eziqhelekileyo; grey, amehlo aluhlaza; isikhumba; ukuguqa kwintombi; i-Rh ingxaki; I-blood type kunye nezinye iimpawu. Iigulo eziphezulu kunye nezigwenxa eziphambili zikwaxanduva lokulungiselela izifo ezithile.
Ngoko, umntwana ufumana isethi yamagciwane aphezulu. Ngokomzekelo, umntwana unokuba nombala omnyama womnweba, amehlo omama omdaka, iinwele zika-ugogo ezinqamlekileyo kunye nomntakwabo "onenkani". Uluhlu lwelifa lezakhi zofuzo lubonakala njani? Umntu ngamnye unemizimba yesibini - evela kumama, nakwabawo. Ngokomzekelo, indoda nomfazi banamabala omdaka, kodwa elowo kubo unesifo esinoxanduva lombala welanga oluhlaza okomntu ozuze kubazali. Kwi-75% yamatyala eli qela liza kuba nomntwana onamabala omdaka, kwaye ngama-25% - amehlo anesibhakabhaka. Kodwa ngamanye amaxesha, abazali abajongene nokukhanya bazalwe ngabantwana abanamabono amnyama, kuba abazali babenomdla obunobangela obumnyama bamehlo, owadluliselwa kuwo, ngokubhekisele kubazali babo, kodwa akazange abonakale njengowona ophezulu. Ngamanye amazwi, kunzima ngakumbi kwaye kunzima kunzima kunokuba nje umzabalazo weengqungquthela eziphathekayo kunye nezigulane.
Idatha yangaphandle yomntu yiphumo lokuxuba amajethi amaninzi, ngoko umphumo awukwazi ukuhlala uqikelelwe. Masinike omnye umzekelo ngombala weenwele. Ngokomzekelo, indoda inomdla ophezulu wokunyuka kweenwele ezimnyama, kwaye umfazi unomdla wokugqithisa kweenwele ezimhlophe. Umntwana wabo, mhlawumbi, uya kuba nomthunzi omnyama wobunwele. Yaye xa lo mntwana ekhula, abantwana bakhe banokuba neenwele ze-blonde. Kutheni oku kwenzeka? Ukusuka kubazali, lo mntwana wathola iigeni ezimbini - i-gene ephezulu kakhulu yobunwele obumnyama (obonakalisa yona) kunye nomzimba ogqithisileyo weenwele ezimhlophe. Lo mzimba ogqithiseleyo ungasebenzisana neengqungquthela eziphathekayo zomlingani ekukhulelweni komntwana kwaye uzuze kule "mfazwe". Ngaloo ndlela, umntu unokufumana iijeni kwiidlozi ezikude, umzekelo, ukusuka kumakhulu-makhulu, onokumangaliswa kubazali.
Ngamanye amaxesha umfuziselo ofanayo ungenza imisebenzi emininzi kwangoko. Umzekelo, ukuba umbala wamehlo kukho iindiza ezininzi ezidibeneyo ngeendlela ezahlukeneyo. Kodwa ezinye iinkqubo zilandelwa. Ngokomzekelo, abazali abanamehlo abamnyama abayi kuba nabantwana abanamehlo aluhlaza. Kodwa abantwana abanamabala abomdaka bazalwa ngokugqithiseleyo ngee-brown (ngeentlobo ezahlukeneyo zee-shade) abazali, kodwa i-eyed blue-eye iyakwazi ukuzalwa. Kwabazali abanamehlo aluhlaza okwesibhakabhaka okanye abomvu, mhlawumbi, kuya kuba nabantwana abanamabala aluhlaza okwesibhakabhaka okanye abantwana abanamakhono.
Kunzima ukuqikelela ukukhula komntwana kunye nobukhulu benyawo. Ezinye iziganeko kule nto okanye ukuba ukukhula kulandelwa, kodwa apha konke akuxhomekanga kuphela kwi-genetics. Enyanisweni, abazali abaphezulu banomntwana ngaphezu komyinge. Kodwa kuninzi kuxhomekeke kwindlela umama ozayo ayeza kudla ngayo ngexesha lokukhulelwa, ukuba umntwana wasondliwa njani, zeziphi izifo ayenayo, njalo njalo. Ukuba umntwana njengomntwana uphelelwa kakuhle, ulala, aqhubeke kakhulu, angena kwizemidlalo, ngoko unako onke amathuba okufikelela kwizinga eliphezulu lokukhula. Kwakhona, ngamanye amaxesha kubonakala ukuba izibonakaliso zobuso zidluliselwa ngokwasemzimbeni kubantwana abavela kubazali, ukubonakalisa ubuso.
Iimpawu zobuntu, ububele, nazo, zitshintshiselwa ngokwezityalo, kodwa kunzima ukuqikelela. Kodwa uhlobo lomntwana alukho kuphela i-genetics, luyimfundo, imeko, indawo kwindawo yoluntu. Abantwana nabo bafumana iimpawu ezithile xa bethetha nabazali babo, ngoko abazali kufuneka baqaphele kwaye baqaphele - babonise iimpawu ezilungileyo, babonise abantwana umzekelo ofanelekileyo wokuziphatha.
Kwaye ke, inqanaba lobunkokheli, ubunzima beengqondo, ukuthambekela kwezesayensi ezahlukahlukeneyo, ukuphishekela izinto, izinto zokuzilibazisa, nazo, zidluliselwa kwi-genetically (mhlawumbi - ukuya ku-60%), umzekelo, ukunyaniseka kumculo, ukudanisa, ezemidlalo, izibalo, ukudweba njalonjalo. Ukongezelela, kwanekhenkce, iphunga kunye nezinto ezikhethiweyo zemibala zizuze njengefa, umzekelo, uthando olushushu okanye oluhle nolunjalo.
Kukho uluvo lokuba amakhwenkwe afana nomama, kunye namantombazana anjengebawo. Oku kuyinyaniso, kodwa inxenye kuphela. Enyanisweni, abafana bahlala bebukeka kakhulu njengomama wabo, kuba bazuze kwi-X-chromosome yakhe, equle inani elikhulu leengcambu ezijongene nokubonakala, kwaye upapa ufumana i-Y-chromosome. Amantombazana athola i-X ye-chromosome efanayo kunye noyise nonina, ngoko ke banokufana nabo bobabini, kunye nomnye umzali.
Ubulili bomntwana ongakazalwa luxhomekeke ngokupheleleyo kumntu. Iiseli zesini zesini zinezi-X-chromosomes kuphela, oko kuthetha ukuba nayiphi na i-ovule ngexesha lokukhulelwa, ngokulandelanayo, iqukethe i-X-chromosomes kuphela. Kwaye iiseli zesini zesini ziqukethe ii-chromosomes ze-X kunye ne-Y. I-Y-i-chromosomes inoxanduva lokulala ngesondo lomntwana. Ngaloo ndlela, ukuba i-X i-chromosome yowesifazane idibana ne-X ye-chromosome, intombazana iza kuzalwa. Yaye ukuba i-X i-chromosome yowesibini idibana ne-Y chromosome yindoda, kuza kuzalwa umntwana.
Enyanisweni, akunakucingela ukuba yintoni isondo ngomntwana, kunye nombala oya kuba nawo kunye neenwele. Into ebalulekileyo kukuba umntwana abe nempilo kwaye uyavuya, kunye nabazali bakhe! Ngoku uyazi ukuba kubaluleke kangakanani ukuveliswa komzimba, abazali, ukuba umntwana uya kuba yintoni, kuxhomekeke kubufa bakho! Musa ukulibala ukukhokela indlela efanelekileyo yokuphila!
