Indlela Hybridological

Njengokuba kufanele wakubona abaninzi, imfuza na ukumkanikazi Sciences. Eneneni, imiba enxulumene nale ngenzululwazi, yenye yezinto ezibalulekileyo, njengoko linokumisela, njengoko bathi, umgangatho wenzala ezelwe. Genetics Ihlala indinceda ekucombululeni iingxaki ezifana ukufuna unyango ezintsha kwezifo.

Enye indlela eya kusebenza yemfuza na indlela Hybridological. Oku akuthethi ukuba omnye, njengendlela ukufunda yofuzo. umongo wayo oku: ukuba kukho sreschivanie iintlobo ezimbini, inzala yabo iya ilifa isethi iimpawu, eziya kumiselwa kweejini. Loo ndlela yaziwa njenge ndlela Hybridological Mendel. Yena lowo wokuqala abo bayiwelayo iintlobo ezahlukeneyo ertyisi, leyo hlukile enye kwenye kwezinye iinkalo. Umzekelo, ukuba kukho umahluko kubukhulu iimbewu, imilo, umbala, kwaye isiqu ukuphakama njalo njalo. Mendel olwenziwe imisebenzi emininzi yokunqumla eziphilayo ezahlukeneyo waphawula indlela obonakala ngayo yonke imiqondiso izizukulwana yokuqala, yesibini nabanye hybrids. Izazinzulu msebenzi baye baqhuba iintlobo ezininzi ertyisi, ngoko waba nako ukumisa ezinye iipateni enxulumene umlinganiselo ubuninzi izityalo hybrid, kwaye zikholisa ukuba ezinye iimpawu eyahlukahlukeneyo sokuqala.

indlela Hybridological lungahlulwa-hlulwa zibe iintlobo eziliqela. Elula kwezi ukuba ezinye, njengokuba umnqamlezo monohybrid. Oku kuphela iiyantlukwano ezimbalwa phakathi iifom lobuzali, njengoko umthetho, oko ngokoqobo isibini kweempawu.

Ukuba unike imizekelo ezithile, ibizwa ngokuba yokunqumla phakathi kwiintlobo kunye imbewu i-ertyisi eziluhlaza ebengezelayo. Emva yemifuniselo, Mendel weza izigqibo eziye ngabanye postulates ngayo imizila yemfuza. Okokuqala, sithetha malunga ulawulo enxulumene ngokufanayo isizukulwana lokuqala gqith. Okwesibini, kufuneka ukuba athi malunga isizukulwana yesibini komthetho cleavage gqith. Kwaye, okwesithathu, kufuneka uqaphele hypothesis of ukusulungeka gametes.

Ukuba sithethe isizukulwana yokuqala ngokufanayo kolawulo, kuyimfuneko kuthi ukuba ithetha ukufana besizukulwana sokuqala kunye nabazali kuzo zonke ngezizathu.

Apha umntu uyakwazi ukubona ukukhonya ngokupheleleyo iimpawu ngumzali omnye ngaphezu nezinye iimpawu.

indlela Hybridological nga zizakujongwa njengo ityala okhethekileyo uhlalutyo yemfuza. Yena ngokuqhelekileyo lwandulelwe ebizwa ngokuba yi- indlela lokuzala. Kuyimfuneko ukuba ukhethe okanye ukwenza izinto ekrwada, nto leyo iza kuthi ke nayo kufundwa. Mendel kulo mzekelo basebenza iimbewu ertyisi ukuba self-ukuhlakanipha.

Yinto akukho mfihlakalo ukuba kwezinye iimeko, inkqubo leyo ekuthiwa indlela Hybridological ngqo ayinakusetyenziswa. Oku kusebenza ilifa iimpawu ebantwini. Inyaniso kukuba kulo mzekelo lungenakucwangciselwa kweenkomo kunye nevzmozhno ukunika parameters ezifana nokuchuma, kwakunye nexesha ukufikisa. Ngenxa yesi sizathu, izakhi zisetyenziswa kunye nezinye iindlela.

Umzekelo, iindlela cytogenetic. ukufunda ababandakanyekayo cytogenetics zesayensi zazo. It akukhethi into ezifana uhlalutyo Hybridological, kodwa sele ukufunda yenethiwekhi olubonakalayo yolwazi yemfuza. Asinto nto kodwa mitotic, meiotic kunye zofuzo polytene kunye mitochondria kunye plastids. Ngoko ke, iindlela cytological, kuqala kwiinto zonke, ibandakanya isifundo zofuzo.

Ukuze wenze oku, sebenzisa ndlela zilandelayo zophando: indlela microscopy ukukhanya, kwakunye neendlela ezininzi mikrospicheskih iimvavanyo, eziqhutywa ngoncedo kwezinye izixhobo ze-elektroniki.
