Namuhla, wonke amadoda angabaza angathola ulwazi mayelana nobaba, ngenxa yokuqalwa okuhlakaniphile - ukuhlola i-DNA ekhaya. Kuyini lokhu kuhlaziywa, okudingekayo ekuziphatheni kwayo nokuthi yini ekuthembekeni komphumela owatholiwe, sizokutshela kule ngqungquthela.
Ukuhlolwa kwezilwane ekhaya
Ngesikhathi sokuqala ukuzwa mayelana nokuhlaziywa kwe-DNA emndenini ekhaya, abaningi bacabanga ukuthi kukhona uhlobo lwe-mini-laboratory noma idivayisi njengokuhlolwa kokukhulelwa. Kodwa empeleni, ukuhlola i-DNA eyenziwe ngokwenza kube yilabo abathandana nabo kubizwa kuphela ngoba ekhaya i-sampulini isetshenzisiwe, eyathunyelwa ebhokisatri. Eqinisweni, lokhu kuyisethi esikhethekile ehlanganisa izinti eziyinyumba, ama-envelope enemibala nemilayezo yevidiyo ngencazelo eningiliziwe yokuthi kufanele wenze kanjani inqubo yokuqoqa amaseli (buccal epithelium) kusuka ngaphakathi kwesikhumba. Ukuqoqwa kwempahla yezinto eziphilayo kuyenziwa ngokusolakala ukuthi ubaba nomntwana, amangqamuzana omama enza lula ukutadisha, kepha akubhekwa njengesibopho. Ngemva kokuthola i-epithelium ye-buccal, ifakwe emvilophini ekhethekile futhi ithunyelwe ebhokisithri lapho i-DNA kababa nengane iqhathaniswa ngqo.
Ukuhlaziywa kuthatha izinsuku eziningana (2-5). Imiphumela ibikwa ngqo kumakhasimende, njengoba ayinolwazi oluyimfihlo olungabonakali kubantu besithathu nezinhlangano zombuso. Ukunemba kwalolu cwaningo kungu-100%. Kumele futhi kucaciswe ukuthi ekuhlolweni kwe-DNA kwezingane ekhaya, imvume eqoshiwe yomama, ubaba nomntwana (emva kweminyaka engu-16) kuyadingeka.
Ngokungangabazeki, ukutholakala okunjalo kokuhlolwa kobuhlobo kubangele ukubuyekezwa okuphikisanayo. Ngakolunye uhlangothi, kuyithuba lokuba wonke umuntu ongabaza ukuqinisa ubudlelwane nengane, ngakolunye uhlangothi - ukungathembeki kohlelo olunjalo kungabangela isahlukaniso. Yingakho isinqumo sokudlulisa ukuhlolwa kwesibambiso kufanele silinganiswe futhi sihlangane.
