Seshiri zvisangane? Features dzokubereka nadzo

Kirasi Birds - iri yoga bazi zvishoma nezvishoma mhuka. Neakatanga kubva nezvinokambaira. Zvisinei, mhuka boka iri, vakakwanisa kuchinja kuti kutiza.

Asati atendeuka kuti mubvunzo sei kuberekesana shiri, funga nezvezvinhu zvipenyu yavo.

General cho mukirasi

Advanced zviri musangano anotevera zvimwe.

1. High kwevari tsinga kukura, uye somugumisiro guru siyana embodiments ose adaptive maitiro.
2. The chenguva refu muviri tembiricha, iyo imhaka ndichibvunza muviri.
3. Tichienzanisa omurume zvidzidzo uye subtypes zvemhuka, shiri dzine kubereka zvakawanda akakwana mashandiro, zvichiguma zvokudya hatching mazai, uye vana.
4. Kuwanikwa nhengo kuti adaptive ndege uye panguva imwecheteyo, kukwanisa kufamba pamusoro pemvura yacho, uye mune mamwe marudzi - kukwanisa kushambira uye kutama nomumvura pamusoro.

The pamusoro kirasi zvinhu kubvumira mhuka idzi kupararira munyika yose.

Nhengo yomunhurume

Testes - peya miviri bhinzi serin'i, izvo dzinongoda pamusoro neitsvo. Vari yakaturikwa kubva mesentery. The kukosha testes kunosiyana-siyana gore rose. Munguva rutoto mwaka, mitumbi izvi zvawanzwa. Saka, Finch Somuenzaniso, vanogona kuwedzera zvakare muna 1125, uye dzimwe Starling 1500 nguva.

Nokuti mukati menyika testes zvakabatanidzwa diki zvinoshandiswa. Abve kwavari vas efferens, kuratidza akaererana ureter uye mainozonodira cloaca. Kune eshiri uyo vas efferens vanoumba duku kuwedzera - mbeu matema iyo semusimboti mhando dura kuti dzisingaoneki.

Copulatory nhengo asina zvose zvipenyu. Nhengo yemukomana mune shiri iri diverticulum pamusoro cloaca. Hazvina ndiripo mhou, tinamou, hanzi. In bustards, shuramurove uye herons copulatory nhengo iri wokugaya.

Pakupindura sei kuti zvisangane shiri, zvinokosha kuziva kuti dzakawanda zvipenyu muchangosangana ndepana tichiregeredza dzepedyo nzira iri pokubuda napo kuti navarandakadzi, kana mukono ejaculates urume.

Female sikarudzi

Kunyanya kukura dzokubereka nadzo kuti vakadzi vari shiri ndechokuti zvinoshamisa asymmetric dzakawanda marudzi, kureva Inoitwa ovary kuruboshwe uye oviduct kuruboshwe. ovary Right ikabuda shiri mishomanana: loons, mazizi, huku, vafudzi, remaparrot, vamwe nyama. Asi kunyange zvakanaka dzakabudirira simbi iyi kazhinji anoshanda. It saka zvinoitika kuti zai yakura zvakarurama ovary ndiyo goho kubva oviduct kuruboshwe.

Chikonzero asymmetry ichi ndechokuti munhukadzi shiri mazai makuru ane goko rakaoma, izvo kufamba ari oviduct kwenguva refu - anenge 2 maawa.

Ovary inomiririra granular irregularly kuumbwa muviri. Riri pamberi itsvo. Kukura ovary kunoenderana kukura pakati mazai ari mariri.

Oviduct - chinhu refu chubhu kuti akakura zai unotii. Hwakabatana pamugumo kusvika cloaca uye mumwe - nomuviri mhango.

Oviduct ine madhipatimendi anoverengeka. Origin akapfuma chaiwo mumasero kuti secrete puroteni. Muchikamu chino zai iri maawa anenge 6 uye rinosanganisira wokutanga runodzivirira. Chikamu chechipiri zvakawanda pachena, zviri akafukidza zai anoshongwa podskorlupovymi. Next Front of oviduct - muchibereko chemusikana. It Zai maawa anenge 20. Kune akaumba calcareous goko uye pigments siyana izvo hwave huchiitirwa. Last weboka - the nyinyo kuti zai ake anopinda cloaca, uye ipapo - kunze.

All ndima mazai kubva oviduct yehuku ndiyo maawa anenge 24, kubva hangaiwa - maawa 41.

kunyanya ruminant

Pasinei zvinonyatsorehwa maberekero zano, ose mhando nomumwe shiri.

Kudzidza mubvunzo sei kuti zvisangane shiri musha, zvakadai somunhu huku Somuenzaniso, zvinokosha kuyeuka kuti vanogona mazai pasina murume. Izvi zvinoreva kuti ichibviswa zai iri unfertilized.

varume testes vanotanga kushanda, kukura kukura - varume vari kugadzirira muchangosangana. Pane kuchinjwa majini zvokunyama kuti mukadzi, iyo pashure imwe nguva kutanga mazai. nhamba yavo haisi chete akasiyana eshiri.

The kubereka shiri inoitika nemwaka siyana. Biology of kwemarudzi siyana chaizvo. Kana mumwe mhando takagadzirira dzinoberekera mangwanani yechirimo, imwe - chete pakati chirimo. Vamwe shiri dziri ndakagara uye dendere panzvimbo, asi vamwe vanosvika vachibva kunyika kure chete nokuda kwenguva nesting uye maberekero.

Kuti tinzwisise zviri nani sei shiri zvisangane imwe mhando, zvinokosha kuongorora nomumwe zvechadenga pabonde ezvinhu vamiririri vayo.
