Mhlawumbi ukuba intombi enyulu yazala, okanye Yintoni parthenogenesis

Ngokuqinisekileyo ngamnye uyazi ibali izibhalo. UMariya, ukuba onyuliweyo nguThixo, liqaphele ukukhanya umntwana Nasono akhulelwe. nokuba ngenene kwenzeka okanye nje ziziphumo ngqondweni zasendle ababhali xesha, namhlanje kunzima ukutsho. Kodwa ke makwazeke, ukuzalwa enyulu kwihlabathi lethu - Kuyinto eqhelekileyo. Yintoni parthenogenesis yaye yintoni umongo wayo?

umhlaba omangalisayo

Mhlawumbi omnye mkhulu amiswa indalo yethu kunganxulunyaniswa ncam imvelaphi yobomi. Apho ndivela khona ngubani ngumdali yonke into - imfihlelo ngasemva amatywina ayo asixhenxe. Kodwa ubani uMdali wethu, ukuba ngokugqibeleleyo wanyamekela, ukuze ubomi emhlabeni blue eye ezingomanga up. iintlobo ezahlukeneyo ukuba ahlale emhlabeni, nako ngokutsha ngokwalo iindlela ezininzi ezahlukeneyo, maxa wambi engalindelekanga kakhulu.

parthenogenesis

Yintoni parthenogenesis? Le obhinqileyo uyakwazi ukunika ubomi kwisizukulwana esitsha ngaphandle naye a ngesondo - into eyindoda. Oku akuthethi ukuba amaduna akuyomfuneko konke konke, bona, Kakade ke, kubalulekile. Parthenogenesis ayikho indlela yokuzala maqanda, njengokuba ezinye izityalo (amagqabi, umzekelo). Kodwa ukuba kuyenzeka ukuba imazi ngesizathu esithile ayikwazanga ukufumana yokwahlulwa ukusukelwa kunye ukuchumisa lwenzeke, kusesemini nako ukuvelisa inzala yinxalenye ozelwe ngaphandle inxaxheba yakhe. Le khono inika elingama elukhuni kuhle kakhulu. Xa inani ukuwa, elilithokazi ngexesha elifutshane ungenza ngenxa labemi aqhubeke nogqatso. Lowo ngumongo parthenogenesis.

Enye inkalo ebalulekileyo yale yokuzalela - nokulawula umlinganiselo amadoda kunye nabasetyhini. Ngoko ke, umzekelo, iinyosi bavela unfertilized amaqanda drones (amadoda), kunye ayaqhama - abantu abasebenza, zonke ezo abafazi.

iintlobo parthenogenesis

Yintoni parthenogenesis nendlela oko kunokuthi kwenzeke ngezo okanye ezinye izilwanyana? Olunye uhlobo, loo nto ithathwa indlela yokuza- engundoqo (esisinyanzelo). Kuba nezinye iintlobo, oko Zijika, oko kukuthi ngamaxesha kubonakala imbewu amaqanda unfertilized, kodwa ngakumbi ngoncedo eyindoda. indlela olukhethekayo okanye ezizodwa yokuzala ivumela kuthetha ukuphila kwiimeko ezininzi ezinzima zobomi, ezifana na uhlobo parthenogenesis kubo. La macala ngaphandle kunoko, ngenxa yokuba ngokuqhelekileyo ezi zilwanyana anamathele ukuzala ulala.

Parthenogenesis emfuyweni

Yintoni parthenogenesis? Le yinkqubo apho iqanda umzali, ukuba unfertilized, uqala ukuphuhlisa, ukuze ajike abe ngumntu omdala ophilayo yokuba yinxalenye. Parthenogenesis zisenokwahluka kakhulu kwiintlobo ezahlukeneyo. Ngoko ke, umzekelo, yokuzala parthenogenesis iinyosi yohlukile kakhulu kwezinye izinambuzane ukuzala, umzekelo, iimbovane.

Ukwazi ukuba parthenogenesis yaye kwenzeka njani, baphenjelelwa kakhulu uphuhliso inzululwazi wanika yokukhawulezisa ukuvela imikhwa ezithile kolu shishino. Umzekelo, oosonzululwazi bafumanisa ukuba le parthenogenesis le silkworm iqala emva ukubekwa kumaqondo obushushu ezithile. Oku olukhawulezisiweyo kakhulu inkqubo lokuba zikhe ezi zinambuzane.

, Yintoni na le nto parthenogenesis, yaziwa kakuhle ukuba iinyosi kunye nabavelisi isilika ezingenamqolo abaninzi basebenzisa kuyo ngale ndlela. Nasono Kwakhe Ekukhawulweni kudla eyenziwa ezinye iintlobo amacilikishe, intlanzi, inkqubo eqhelekileyo kubameli zehlabathi izityalo, kukho nkqu ikarikuni parthenogenetic.

Abameli inzululwazi abasebenza kwi sifundo sale nzima ethile. kwenziwe amalinge abaninzi baye ukuqalisa parthenogenesis izilwanyana ezinegazi elishushu. Imizekelo lead ngelishwa akunakwenzeka, kuba abanye ukukhula iseli kunye nophuhliso iimbumba zenzeke, kodwa ngaphambi kokuba Inqanaba lokugqibela, zange ifike. Inzala ngakwicala iyeza nako ngokuba kakhulu. ukuba uvavanyo luqhutyiwe, emva koko ke oko kwazeka ukuba uninzi izibini abangakwaziyo nomntwana, ngenkoliseko nobuganga ukuzalwa enyulu enjalo. Ngubani na owaziyo, mhlawumbi ekugqibeleni ikhuselo imfihlelo izakuvula. Kwaye ummangaliso iya kuzaliseka - parthenogenesis anganika ubomi kunye usana yabantu.
