Akekho ozophikisana nekhono lomfazi lokukhulelwa ngenxa yocansi lobulili, kungakhathaliseki ukuthi kwenzekani lokhu. Kodwa-ke, kunemigomo eyaziwa kakhulu engasiza ekuqedeni iphupho labo emibhangqwaneni engakaze ikhule ngokukhulelwe. Enye ye "tricks" engakwazi ukwandisa amathuba akho noma ukusebenzela ukukhulelwa okusheshayo yizikhundla ezikhethekile ezenzweni zobulili. Mayelana nabo, kanye nezinye izinkolelo zokukhiqiza inzalo, funda ngezansi.
Yini?
Ngakho-ke, uma umbhangqwana ophilile othanda ukuba nezingane futhi ongenayo ukuphambuka, akhulelwe , abantu baqala ukucabanga ngalokho abakwenzayo okungalungile, kufaka phakathi nendawo lapho kubalulekile ukukhulelwa ingane.
Ukuze sithole leli qiniso elilula, kumelwe sikhumbule izifundo zesikole emlandweni wemvelo noma nge-physics, ethi yonke into, kuhlanganise nomuntu, ilalela imithetho yokukhangwa. Futhi lokhu kusho ukuthi sizokhuluma ngendlela elula, eqondile, okufanele senziwe ukuze sisize:
- Ilungu langena ngokujulile ngangokunokwenzeka, lifinyelele eduze ngangokunokwenzeka esibelethweni.
- I-sperm ngesikhathi sokujula futhi emva kwalokho kufanele "uhlale" emzimbeni isikhathi eside ngangokunokwenzeka, ukuze i-spermatozoa ifinyelele i-ovum.
Ngokusobala, izimo ezinhle kakhulu zokukhulelwa kumele zisetshenziswe ekuxazululeni imisebenzi evezwayo.
Okokuqala, okwesikhashana udinga ukuhlehlisa ukuhleleka okuqondile, ubulili endaweni ehlezi futhi ubeka nomlingani "ovela phezulu". Konke lokhu kuphuthuma ukugeleza kwesidoda esivela esiswini.
Okwesibili, kumele siyeke ukusebenzisa amakhemikhali okwenza i-spermatozoa ibe yilapho, noma iwabulale.
Yebo, futhi, okwesithathu, kumele sithole izimo ezinhle kakhulu zokukhulelwa kwengane. Futhi azikho eziningi zazo.
Ukuthutha
- Isikhundla se-knee-elbow - ngomzamo wokuthola inzalo, ubuyele emuva ezweni lesilwane, elibhekana nalo msebenzi ngaphandle kobunzima obukhethekile. Owesifazane uguqa, ephakamisa isikhumba, futhi le ndoda itholakala ngemuva. I-positi inikeza ithuba lokungenwa okuphezulu, i-pelvis ephakanyisiwe ayivumeli isidoda ukuba siphume.
- Ukumiswa kwezithunywa zevangeli - ubulili obuvamile ngaphandle kokudlula, kodwa ngomphumela. Lesi yisikhathi esihle kakhulu sokuhlolwa sokukhulelwe. Umlingani ulele ngemuva kwakhe, futhi lo muntu uphezulu. Kulula ukufeza kokubili ukujula kokungena, nokulondolozeka okuthembekile kwesidoda esiswini. Ngemuva kocansi, abesifazane batuswa ukuba babeke imithwalo ngaphansi kwamathambo okwesikhashana. Futhi abanye bayeluleka ngisho nokuba babe ngumuthi we-birch, kodwa musa ukwenza i-algorithm yokukhulelwa kwezingane ngaphandle kocansi.
Kuphi?
Yebo, uthanda ucansi echibini, ibhuku lokugeza, ukugeza, njll. Kodwa njengoba usuhambe kakade ekuhleleni kokukhulelwa, zilungiselele ukuthi ubulili emvelweni wamanzi yiyona engcono kakhulu ekuqaleni kokukhulelwa.
Masikhumbule ukuvuthwa komhlaba kanye neminye imithetho yeplanethi yethu. Uzovumela kanjani ukuba i-spermatozoa ifinyelele iqanda, uma, uxolisa ngokoqobo, bahlanza nje ngamanzi?
Ubulili obuhle kakhulu bokukhulelwa yizo ezolile, ezilinganiswa ngokobulili ezimweni ezihlelekile. Ngandlela-thile, ngokungafani nenkolelo evamile mayelana nokulutha kwabantu besilisa ngokuya ocansini ngokweqile, empeleni, bazizwa beqiniseka kakhulu embhede womkhaya ophansi. Futhi ukucindezeleka nanoma yikuphi ukungezwani yizitha ezimbi kunazo zonke zesilisa.
Nini?
Isikhathi esihle kakhulu sokukhulelwe siyihora ezingama-24 ngaphambi kokuvuthwa kanye namahora angu-24.
Ngempela "iStakhanovites" yangempela sithi ithuba lakho lokukhulelwa liyokwandisa nakakhulu ekuzigwemeni. Ochwepheshe balolu cala bancoma ubulili obuvamile njalo ngenyanga njalo, bese ubaleka ngokocansi amasonto amabili. Leli thuluzi lithandwa kakhulu emibhangqwaneni efuna ukukhulelwa umfana.
Iqiniso liwukuthi emva kwamasonto amabili ukuzithiba, amadoda afinyelela phezulu kokuqukethwe kwama-chromosomes angama-Y kumuntu. Futhi "Y" yi-chromosomes yabafana abazayo.
