Njengoba izinyoni sokukhwelana? Izici kwesimiso sokuzala

Class Birds - lena legatsha ehlukile isilwane ezithuthukayo. Zenzeka kusukela ezihuquzelayo. Nokho, Izilwane yaleli qembu, bakwazi ukuzivumelanisa indiza.

Ngaphambi kokuvala yombuzo kanjani izinyoni kokuzalela, cabanga biology yabo.

isici Jikelele ekilasini

Izici ezithuthukisiwe lenhlangano izici ezilandelayo.

1. Amazinga aphezulu sezinzwa ukuthuthukiswa kohlelo, futhi ngenxa yalokho ezihlukahlukene enkulu embodiments yokuziphatha oluhambelana.
2. I njalo lokushisa komzimba okusezingeni eliphezulu, okuyinto ngenxa umzimba olunzulu.
3. Kuqhathaniswa amakilasi ongaphansi futhi subtypes kwezilwane, izinyoni babe neliphelele kunalelo ukukhiqizwa kabusha indlela, okuholela ukunikeza amaqanda ukuchamisela, futhi siyinzalo.
4. Ukutholakala kwezitho indiza eguquguqukayo kanye ngesikhathi esifanayo, ikhono qhubeka ubuso bezwe, futhi ezinye izinhlobo zawo - ikhono ukubhukuda bese ukuhambisa ngokusebenzisa phezu kwamanzi.

Okungenhla izici ekilasini avumele lezi zilwane chithi saka emhlabeni wonke.

Wabona isitho sowesilisa

Testes - pair of emizimbeni emabhontjisi emise, okuyinto okungadingeki phezu phezulu izinso. Basuke okwesikhashana kusukela mesentery. Inani testes kuyahlukahluka unyaka wonke. Phakathi nenkathi yokuzalela, lezi zindikimba bayanda. Ngakho, Finch, isibonelo, bangase ukwandisa futhi emuva 1125, futhi ngezinye izikhathi Starling 1500.

Ukuze ingaphakathi testes enamathiselwe ezihlobene encane. Dedani kuzo vas efferens, edlulisela kuhambisana ureter futhi uthululela phakathi cloaca. Kukhona izinhlobo eziningi zezinyoni ngubani vas efferens yakha encane ukunwetshwa - Bubbles imbewu okuyizindawo uhlobo kwesigubhu ngoba isidoda.

isitho Copulatory abuzange zonke izinhlobo. Isebenze umthondo e izinyoni kuyinto diverticulum we cloaca. Kuyinto ekhona izintshe, tinamou, ihansi. Ngo bustards, storks nezindwandwe copulatory isitho kuyinto esingesihle.

Iphendula umbuzo ukukhwelana inyoni, kuyafaneleka ukuthi ezinhlotsheni eziningi zezinto eziphilayo kokukhulelwa kwenzeka ngezithukuthuku indlela abaseduze lo ukuzwakalisa of kwabesifazane nabesilisa, lapho owesilisa ejaculates isidoda.

izitho zangasese Female

Ikakhulukazi ukuthuthukiswa kwesimiso sokuzala abesifazane izinyoni ukuthi kakhulu quin ezinhlotsheni eziningi zezinto eziphilayo, ie Siqukethe esibelethweni kwesokunxele bese oviduct kwesokunxele. esibelethweni Right eba izinyoni ezimbalwa kuphela: loon, izikhova, inkukhu, abelusi, zopholi, ezinye inyamazane. Kodwa ngisho evuthiwe yensimbi kuleli cala akuvamile isebenza. Kuqondane ukuthi iqanda wavuthwa e esibelethweni esifanele okukhiphayo kusukela oviduct ngakwesokunxele.

Isizathu salokhu asymmetry ukuthi nensikazi amaqanda emikhulu nge igobolondo kanzima, okuyinto ukuhambisa kule oviduct isikhathi eside - amahora angaba ngu-2.

Esibelethweni limelela luyimbudumbudu umzimba ezimise ngendlela engavamile. Itholakala phambi izinso. Ubukhulu we esibelethweni incike ukuvuthwa amaqanda nokuba kuwo.

Oviduct - kuba tube eside ukuthi zikhula Iqanda uhamba. Ixhumeke at komunye umkhawulo kuya cloaca kanye nezinye - ne ingaphakathi lomzimba.

Oviduct siqukethe neminye iminyango eminingana. Umsuka nezindlala ocebile ekhethekile secrete amaprotheni. Kule ngxenye iqanda imayelana 6 amahora imbozwe ungqimba wokuqala zokuzivikela. Ingxenye yesibili kucashile, kuyahlanganiswa ne amaqanda amagobolondo podskorlupovymi. Front Landelayo we oviduct - kwesibeletho. It iqanda amahora angu-20. Kukhona akhiwa calcareous igobolondo futhi eba nezakhi zombala ezenza ezihlukahlukene okuyinto bangcolisé. division Kugcine - sangasese egg wakhe ungena cloaca, bese - ngaphandle.

Zonke ukudlula amaqanda kusukela oviduct we inkukhu amahora angaba ngu-24, ijuba - amahora 41.

ikakhulukazi zizalela

Naphezu jikelele zizalela scheme, kuzo zonke izinhlobo zezinyoni ngabanye.

Ukutadisha umbuzo ukukhwelana ekhaya inyoni, ezifana inkukhu isibonelo, kuyafaneleka ukukhumbula ukuthi bangakwazi amaqanda ngaphandle besilisa. Lokhu kusho ukuthi iqanda aphumayo kuyinto unfertilized.

testes besilisa ziqale ukusebenza, sikhule ngobukhulu - abesilisa zilungele ukuze sithele. Kukhona ukudluliselwa zofuzo ukuze owesifazane, okuyinto ngemva kwenkathi ethile aqale amaqanda. Isibalo sabo akufani e zinhlobo ezahlukene zezinyoni.

I kabusha izinyoni isifika zonyaka ezahlukene. Biology of zinhlobo wehlukile kakhulu. Uma uhlobo oluthile lwento ephilayo esekulungele ukuzalela ngasekuqaleni kwentwasahlobo, elinye - kuphela phakathi ehlobo. Izinyoni ezithile ngaphandle kokuzivivinya futhi isidleke endaweni efanayo, kodwa abanye bevela emazweni akude nje kwenkathi lokushutheka futhi zizalela.

Ukuze siyiqonde kangcono indlela izinyoni sokukhwelana uhlobo oluthile, kubalulekile ukuba sihlole izici ngamunye kohlelo ngokocansi nabameleli bayo.
