THE kubereka kosinthasintha, yemwenso amadziwika kuti zachiwerewere, ndi njira yachilendo m'zinyama ndipo imakhala ndi kusinthana kozungulira ndi kubereka komwe kumatsatiridwa ndi kuzungulira kwina. Pali nyama zomwe zimaberekana koma, panthawi inayake m'moyo wawo, zimatha kuberekana, ngakhale sizitanthauza kuti zimasinthasintha mtundu wina ndi zina.
Kusintha kwachilengedwe kumachitika kwambiri muzomera, koma nyama zina zimachitanso izi. Chifukwa chake, m'nkhaniyi ya PeritoAnimal, tifufuza za mtundu uwu wobereka ndikupereka zina zitsanzo za kubereka pa kusinthana kwa mibadwo ya nyama amene amachita.
Kodi mibadwo yosinthira imakhala ndi chiyani?
Kubereka mwa kusinthana kwa mibadwo kapena heterogony ndi mtundu wa kuswana kofala kwambiri muzomera zosavuta zopanda maluwa. Izi zomera ndi bryophytes ndi ferns. Munjira yoberekayi, kubereka komanso kubereka. Pankhani ya zomera, izi zikutanthauza kuti adzakhala ndi gawo la sporophyte ndi gawo lina lotchedwa gametophyte.
Nthawi ya sporophyte siteji, chomeracho chimatulutsa ma spores omwe amapatsa mbewu zazikulu kukula kofanana ndi koyambirira. Pa gawo la gametophyte, chomeracho chimapanga magemu achimuna ndi achikazi omwe, akaphatikizana ndi ma gameti ena ochokera kuzomera zina, zimatulutsa anthu atsopano okhala ndi mitundu yosiyanasiyana yamajini.
Ubwino wosintha kubadwanso kwatsopano
Kubereka mwa kusinthana kwa mibadwo amapeza zabwino zakugonana komanso kuberekana. Pamene chamoyo chimabereka kudzera munjira yogonana, chimapangitsa ana ake kukhala ndi mitundu yolemera kwambiri yamitundu, yomwe imathandizira kusintha kwa mitunduyo. Kumbali inayi, pamene chamoyo chimachulukitsa asexually, chiwerengero cha anthu atsopano omwe amawonekera chimakhala chachikulu kwambiri munthawi yochepa.
Chifukwa chake, chomeracho kapena chinyama chomwe chimabereka mwa mibadwo yosinthasintha chidzakwaniritsa mbadwo wolemera komanso wokhala ndi manambala ambiri, pamodzi kuwonjezera mwayi wanu wopulumuka.
Zitsanzo za mibadwo yosinthana ya nyama
Kusinthanitsa kwachilengedwe kwa nyama zopanda mafupa monga tizilombo mwina ndiye chitsanzo chofala kwambiri komanso chochuluka, koma kuswana kwa jellyfish kumatsatiranso njirayi.
Kenako, tiwonetsa fayilo ya mitundu ya nyama zomwe zimasinthana kubadwanso mwatsopano:
Kubalana njuchi ndi nyerere
Kubereketsa njuchi kapena nyerere kumachitika mwa kusinthana kwa mibadwo. Nyama izi, kutengera mphindi yofunikira komwe amapezeka, adzaberekanso kudzera muzochita zogonana kapena zogonana. onse amakhala mu chisangalalo kapena gulu lenileni, lokonzedwa m'ma castes, lirilonse lomwe limagwira gawo lapadera komanso lofunikira. Zonse nyerere ndi njuchi zimakhala ndi mfumukazi yomwe imakwanira kamodzi pamoyo wawo, kutangotsala pang'ono kuti mng'oma watsopano kapena nyerere zisunge umuna mkati mwa thupi lake m'chiwalo chotchedwa spermtheca. Ana ake onse aakazi adzakhala zotsatira za mgwirizano wa mazira a mfumukazi ndi umuna wosungidwa, koma nthawi ina, anthu akadzakula (pafupifupi chaka chimodzi ngati njuchi ndi zaka zinayi ngati nyerere), mfumukazi idzaikira mazira osakwaniritsidwa. M'malo mwake, pali mitundu yodziwika ya nyerere momwe mulibe amuna, ndipo kuberekana ndi 100% kofanana.
Anthu aku Crustaceans omwe amaberekanso njira zina zoberekera
Inu mitundu yama crustaceans Daphnia khalani ndi njira zosinthira zina. M'nthawi yachilimwe ndi chilimwe, nyengo ikakhala yabwino, daphnia imaberekanso zachiwerewere, zomwe zimangopangitsa azimayi omwe amakula m'matupi awo kutsatira njira ya ovoviviparous. Nthawi yozizira ikayamba kapena pakagwa chilala, akazi amatulutsa amuna adamchinesei (mtundu wa kubereka kwa asexual). Chiwerengero cha amuna mu daphnia sichidzakhala chachikulu kuposa chachikazi. Mu mitundu yambiri, ma morpholoji achimuna samadziwika chifukwa sichinawonekerepo.
Kutulutsa nsomba za jellyfish
Kubereketsa nsomba zam'madzi, kutengera mtundu ndi gawo komwe amapezeka, zidzachitikanso pakusinthana kwamibadwo. Akakhala polyp, adzapanga gulu lalikulu lomwe limaberekanso, ndikupanga tizilombo tambiri. Nthawi ina, tizilombo tating'onoting'ono timatulutsa nsomba zazing'ono zopanda moyo zomwe, zikafika pofika msinkhu, zidzatulutsa masewera aakazi ndi abambo, akugonana.
Kuswana tizilombo mwa kusintha mibadwo
Pomaliza, nsabwe za m'masamba Phylloxera vitifoliae, imabereka ana m'nyengo yozizira, ndikupanga mazira omwe amatulutsa zazikazi nthawi yachilimwe. Zazimayi zimaberekana ndi parthenogenesis mpaka kutentha kutsikanso.
Ngati mukufuna kuwerenga zina zambiri zofanana ndi Kusintha kwa mibadwo ya nyama, tikukulimbikitsani kuti mulowe mu gawo lathu la Curiosities la nyama.
