Impela uzwile ukuthi amakati anemibala emithathu ngaso sonke isikhathi ayizinsikazi. Yiqiniso? Ingabe ngaso sonke isikhathi bangabesifazane?
Kulesi sihloko i-Animal Chest sichaza ukuthi kungani lokhu kwenzeka ngayo yonke imininingwane ukuze uthole ukuthi ngabe kuyisici sabesifazane yini, noma, ngokuphambene nalokho, abesilisa nabo bangaba noboya bemibala emithathu.
Qhubeka ufunde ukuthola impendulo yombuzo: ngoba amakati e-tricolor angabesifazane bese ubona ukuthi akwenzeki ngempela yini kubantu besilisa.
amakati amathathu
Ngo- amakati amathathu, eyaziwa nangokuthi i-carey, ibonakala ngokuveza iphethini eyingqayizivele yombala ejazini. Uboya bayo bunemibala ewolintshi, emnyama nomhlophe. Izilinganiso zombala ngamunye ziyahlukahluka.
Emakati kunemibala emithathu eyisisekelo, omnyama, owolintshi nomhlophe. Yonke eminye imibala ingumphumela wama-gradients nezinhlanganisela zangaphambilini.
Izakhi zofuzo zesilwane zinesibopho samaphethini ezinwele, ezinemigqa, eziqondile, noma ezinamabala, kanye nokufaniswa kombala nombala woboya.
Yini enquma umbala wezinwele?
Umbala woboya emakati wu isici esihlobene nezocansi. Lokhu kusho ukuthi imininingwane yombala wezinwele itholakala kuma-chromosomes ocansi.
Ama-Chromosomes ayizakhiwo ezitholakala ku-nucleus yamaseli futhi aqukethe zonke izinhlobo zofuzo zesilwane. Amakati anama-chromosomes angama-38: ayi-19 avela kumama kuthi ayi-19 avela kubaba. Abesilisa ocansini yilawo ma-chromosomes anquma ucansi futhi ngalinye linikezwa ngumzali.
Amakati, njengazo zonke izilwane ezincelisayo, anakho ama-chromosomes amabili ocansi: X no-Y. Umama unikeza i-X chromosome kanti ubaba anganika i-X noma i-Y.
- XX: Owesifazane
- XY: Owesilisa
Ngo- imibala emnyama neyolintshi zikwi-chromosome ye-X. Ngamanye amagama, ukuze baziveze, i-ch chromosome ye-X kufanele ibe khona.Owesilisa une-X eyodwa kuphela, ngakho-ke kuzoba mnyama kuphela noma i-orange kuphela. Abesifazane abanama-X amabili bangaba nezakhi zofuzo ezimnyama ne-orange.
Ngakolunye uhlangothi, i- Umbala omhlophe akungeni ngemvume ocansini lwesilwane. Iziveza ingakhethi ubulili. Ngalesi sizathu ikati lingaba nayo yonke imibala emithathu. Ngoba anama-chromosome amabili x kanti amhlophe nawo avele.
inhlanganisela
Ngokuya nge-chromosomal endowment etholwa yilowo nalowo, kuzovela umbala owodwa noma omunye. Okumnyama nokusawolintshi kufakwe kwi-chromosome efanayo, uma i-allele ye-X0 ikhona ikati lizoba liwolintshi uma kuyi-Xo kuzoba mnyama. Esimweni se-X0Xo, lapho olunye ufuzo lungasebenzi, lubhekene nokubukeka kwe-tricolor.
Abesifazane bangazuza ifa lenhlanganisela ezintathu:
- I-X0X0: i-orange babe
- I-X0Xo: ikati le-tricolor
- XoXo: ikati elimnyama
Abesilisa banezimbili kuphela:
- X0Y: ikati eliwolintshi
- XoY: ikati elimnyama
Okumhlophe kunqunywa yi-W gene (okumhlophe) futhi liziveza ngokuzimela. Ngakho-ke ungenza inhlanganisela neminye imibala. Kunamakati amnyama nomhlophe, awolintshi nomhlophe namakati amhlophe kuphela.
Izinhlobo zamakati e-tricolor
Ngaphakathi kwamakati e-tricolor kunezinhlobo eziningana. ziyehluka kuphela ngokulingana okumhlophe noma ngohlobo lwephethini yezinwele:
- ikati le-calico noma amakati aseSpain: Kula makati kugqame umbala omhlophe esiswini, esidladleni, esifubeni nasesilevini. Zinezimagqabhagqabha ezimnyama nezisawolintshi esikhunjeni sazo. Okumnyama kuvame ukuba mpunga. Emfanekisweni sibona ikati yalolu hlobo.
- ikati carey noma ufudu: Imibala ixutshwe ngokulingana. UMhlophe uyindlala. Imibala ivame ukuhlanjululwa ngamathoni alula. Okumnyama kubusa.
- ikati le-tabby tricolor: Kukwahlukana phakathi kwalokhu okungenhla. Iphethini ibrindle enemibala emithathu.
Ingabe akhona amakati ama-tricolor wesilisa?
Yebo. Amakati e-tricolor akhona, yize kungavamile kakhulu ukuzibona. Kungenxa ye-chromosomal anomaly. Lawa makati esikhundleni sokuba nama-chromosomes amabili ocansi (XY) anezintathu (XXY). Ngoba zinama-chromosomes amabili e-X, angabonisa okumnyama nokusawolintshi njengabesifazane.
waziwa ngo I-Klinefelter Syndrome futhi kuvame ukudala inzalo. Kuyisifo esingajwayelekile esidala inkolelo yokuthi wonke amakati e-tricolor angabesifazane. Kepha ngoba kuyinkinga, singasho ukuthi ezimweni ezijwayelekile wonke amakati e-tricolor imvamisa angabesifazane.
Qhubeka upheqa uchwepheshe wezilwane ukuthola okuningi ngamakati:
- ukunakekela kanjani ikati
- Ukushisa kwekati - izimpawu nokunakekelwa
- Yiziphi izitshalo ezinobuthi zamakati
