- Izilwane zeHermaphrodite: ezinye izibonelo
IHermaphroditism isu eliphawuleka kakhulu lokuzala ngoba likhona kuma-vertebrate ambalwa. Ukuba umcimbi ongavamile, kuhlwanyela ukungabaza okuningi okuzungezile. Ukusiza ukuxazulula lokhu kungabaza, kule ndatshana yezilwane iPerito uzoqonda ukuthi kungani ezinye izinhlobo zezilwane zikwenze lokhu kuziphatha. Uzobona nezibonelo ze izilwane hermaphrodite.
Into yokuqala okufanele uyicabangele lapho ukhuluma ngamasu ahlukene okuzala ukuthi ukukhulelwa ngamehlo yilokho okudingwa yizo zonke izinto eziphilayo. THE ukuzikhulisa ngokwakho kuyinsiza onayo ama-hermaphrodites, kepha akuyona inhloso yabo.
Yiziphi izilwane ezi-hermaphrodite?
Ukuchaza kangcono ukukhiqizwa kwezilwane ze-hermaphrodite, kufanele ube nemibandela ethile ecace bha:
- Owesilisa: unamageyimu wesilisa;
- Owesifazane: unamageyimu wabesifazane;
- UHermaphrodite: inamageyimu wabesifazane nabesilisa;
- Ama-Gametes: amangqamuzana okuzala athwala imininingwane yezofuzo: isidoda namaqanda;
- ukukhulelwa okuphambene: abantu ababili (owesilisa oyedwa nowesifazane oyedwa) bashintshanisa ama-gametes abo ngemininingwane yofuzo;
- ukuzikhulisa ngokwakho: yena lowo muntu uvundisa ama-gametes akhe abesifazane ngabadlali bakhe bamageyimu.
Umehluko ekukhiqizweni kwezilwane ezi-hermaphrodite
Ngo- ukukhulelwa okuphambene, kukhona I ukuhlukahluka okukhulu kofuzo, ngoba ihlanganisa imininingwane yofuzo yezilwane ezimbili. Ukuzikhulela ngokwakho kubangela ama-gametes amabili nge imininingwane efanayo yofuzo hlanganisa ndawonye, kuphumele kumuntu ofanayo. Ngale nhlanganisela, akunakwenzeka ukuthi kuthuthukiswe izakhi zofuzo futhi inzalo ivame ukuba buthakathaka. Lelisu lokuzala livame ukusetshenziswa ngamaqembu ezilwane ezine-locomotion ehamba kancane, lapho kunzima khona ukuthola abanye abantu bohlobo olufanayo. Masenze isimo sibe sesimweni esithile ngesibonelo sesilwane esine-hermaphrodite:
- Isibungu somhlaba, esihamba ngokungaboni phakathi kwezingqimba ze-humus. Uma kufika isikhathi sokuzala kabusha, akatholi omunye umuntu wohlobo lwakhe noma kuphi. Futhi lapho ekugcineni ethola eyodwa, uthola ukuthi kungubulili obufanayo, ngakho-ke ngeke bakwazi ukuzala kabusha. Ukugwema le nkinga, izikelemu zenze ikhono lokuthwala bobulili bobabili ngaphakathi. Ngakho-ke lapho izikelemu ezimbili zihlangana, zombili izikelemu zikhuleliswa. Uma isibungu singakwazi ukuthola omunye umuntu empilweni yaso yonke, singakwazi ukuzimela ukuze siqinisekise ukuthi lezi zinhlobo ziyaphila.
Ngiyethemba ukuthi, ngalesi sibonelo, ungakuqonda lokho o yizilwane ezi-hermaphrodite nokuthi leli yithuluzi lokuphinda kabili kanjani amathuba wokufakwa kokukhulelwa okuhlukile hhayi ithuluzi lokuzivundisa.
Ukukhiqizwa kabusha kwezilwane ze-hermaphrodite
Ngezansi, sizokukhombisa uhlu lwezilwane ze-hermaphrodite, ezinezibonelo ezimbalwa zokuqonda kangcono lolu hlobo lokuzala:
izibungu zomhlaba
Banobulili bobabili ngasikhathi sinye ngakho-ke, phakathi nempilo yabo, bathuthukisa zombili izinhlelo zokuzala. Lapho iminyundu emibili ikhwelana, yomibili ivundiswa bese ifaka isikhwama samaqanda.
izingulube
Njengezikelemu zomhlaba, kunjalo hermaphrodites unomphela.
ECameroon
Imvamisa iba ngabesilisa ngeminyaka emincane kanti nabesifazane uma sebekhulile.
Ama-oysters, ama-scallops, amanye ama-bivalve molluscs
Futhi unayo ukushintshanaezocansi futhi, njengamanje, i-Institute of Aquaculture e-University of Santiago de Compostela icwaninga ngezinto ezenza ushintsho kwezocansi. Isithombe sikhombisa i-scallop lapho ungabona khona i-gonad. I-gonad "isikhwama" esiqukethe ama-gametes. Kulokhu, uhhafu uwolintshi kanti uhhafu umhlophe, futhi lo mehluko wemibala uhambelana nokwehlukaniswa ngokocansi, kuyahlukahluka kumzuzu ngamunye wokuphila komzimba, lokhu ngesinye isibonelo sesilwane esine-hermaphrodite.
I-Starfish
Esinye sezilwane ezaziwa kakhulu nge-hermaphrodite emhlabeni. Imvamisa kuthuthukiswa ubulili besilisa ezigabeni zobusha futhi shintsha ube ngowesifazane lapho usuvuthiwe. Bangaba nakho ukukhiqizwa kabusha kwe-asexual, okwenzeka lapho olunye lwezingalo zalo luphukile luphethe ingxenye yesikhungo senkanyezi. Kulokhu, inkanyezi elahlekelwe yingalo izoyivuselela futhi ingalo izovuselela wonke umzimba. Lokhu kuphakamisa abantu ababili abafanayo.
Isibungu
isimo sakho se amagciwane angaphakathi kwenza kube nzima ukuzala nomunye umzimba. Ngalesi sizathu, ama-tapeworms ajwayele ukusebenzisa ukuzikhulelisa. Kepha lapho benethuba, bakhetha ukuwela umquba.
Inhlanzi
Kulinganiselwa ukuthi cishe 2% wezinhlobo zezinhlanzi ngama-hermaphrodites, kodwa njengoba iningi lihlala ezingxenyeni ezijule kakhulu zolwandle, ukuzifunda kunzima kakhulu. Emifuleni yasePanama engasogwini, sinesimo esikhethekile se-hermaphroditism. O I-Serranus tortugarum, inhlanzi enabobulili bobabili yakhiwa ngasikhathi sinye futhi eshintsha ubulili nomlingani kuze kube izikhathi ezingama-20 ngosuku.
Kukhona elinye icala le-hermaphroditism ezinye izinhlanzi ezinalo, ukuguqulwa kocansi ngezizathu zomphakathi. Lokhu kwenzeka ezinhlanzini ezihlala emakoloni, ezakhiwa owesilisa omkhulu kakhulu neqembu labesifazane. Lapho owesilisa efa, owesifazane omkhulu uthatha indima yesilisa evelele futhi kuguqulwa ubulili kuye. lezi zinhlanzi ezincane ezinye izibonelo ezilwaneni hermaphrodite:
- Ukugoqa okuhlanzayo (Labroides dimidiatus);
- Clown fish (Amphiprion ocellaris);
- Ibha yokuphatha eluhlaza okwesibhakabhaka (Thalassoma bifasciatum).
Lokhu kuziphatha kwenzeka futhi ezinhlanzini ze-guppy noma ze-potbellied, ezivame kakhulu kuma-aquariums.
amaxoxo
Ezinye izinhlobo zamaxoxo, njenge Ixoxo lesihlahla sase-Afrika(Xenopus laevis), zingabantu besilisa ngesikhathi sezingane futhi baba ngabesifazane lapho sebekhulile.
Imithi yokubulala ukhula esuselwa e-Atrazine yenza amaselesele ashintshe ubulili ngokushesha. Ucwaningo olwenziwe e-University of Berkeley, eCalifornia, luthole ukuthi lapho abesilisa bevezwa ukugxila okuphansi kwalesi sakhi, ama-75% abo ahlanzwe ngamakhemikhali bese i-10% idlulela ngqo kwabesifazane.
