Vana vedu vese vakasiyana uye vakasiyana. Dzimwe nguva kusiyana uku kunobva mumajini avo, kureva, kubva pakuzvarwa. Nhasi tichataura nezvechirwere chinokonzerwa nekuchinja kwemajini kwakadaro, asi chisinganyanyo kutaurwa nezvacho munharaunda. Kureva kuti, masero emukomana ane chromosome yeY yakawedzerwa, kana kuti mukurapa, XYY syndrome. Usatya paunonzwa izvi, ngatinzwisise zvese nezvazvo zviri nyore.
Sei izvi zvichiitika? Chii chinokonzera chirwere cheXYY?
Zvichitaurwa zviri nyore, sero rega rega mumuviri wedu rine chimwe chinhu chinonzi machromosome . Funga nezvawo semabhuku emirairo anovaka miviri yedu. Kazhinji, rimwe nerimwe remasero edu rine mabhuku aya emirairo, kana kuti machromosome makumi mana nematanhatu. Tinoawana muzvikamu makumi maviri nematatu. Tinowana rimwe kubva pazvikamu zviviri, rimwe kubva kuna amai vedu uye rimwe kubva kuna baba vedu.
Pamapeya aya makumi maviri nematatu, mapeya ekutanga makumi maviri nemaviri ndiwo anosarudza humwe hunhu hwemuviri wedu. Peya rechi23 ndiro rinosarudza bonde redu. Kana ari musikana, mapeya aya ndiXX, uye kana ari mukomana, ndiXY.
Heino maitiro anoita chirwere cheXYY. Kana mwana abatwa nepamuviri, pane chikanganiso chidiki chinoitika pakuumbwa kwembeu yababa, zvichiita kuti imwe chromosome yeY iwedzere kumbeu iyoyo. Izvi zvinonzi nondisjunction musainzi yezvekurapa. Zvadaro, sero rega rega mumuviri wemwana wechirume anoberekwa kubva kumbeu iyoyo rine musanganiswa wechromosome yeXYY panzvimbo peXY yakajairika.
Chinhu chakakosha ndechekuti izvi hazvisi mhosva yaamai kana baba . Zvakare, hazvisi zvenhaka. Kureva kuti, baba vane chirwere cheXYY havazopfuuri chirwere ichi kumwanakomana wavo.
Ndezvipi zviratidzo zvemuviri wemwana ane chirwere cheXYY?
Iri idambudziko guru kune vanhu vazhinji. Asi chokwadi ndechekuti, havasi vakomana vese vane XYY syndrome vanoratidza kusiyana kwakakosha kwemuviri. Dzimwe nguva, hapana kana chimwe chinhu chakakosha chinoonekwa.
Rudzi rwemuviri wedu ndiwo murayiro unoumba miviri yedu. Maumbirwo aya emajini, pamwe chete nenzvimbo yatinogara, ndizvo zvinosarudza hunhu hwedu hwekunze (phenotype) hwakadai sehurefu, huremu, uye chitarisiko.
Zvisinei, pane zvimwe zviratidzo zvemuviri zvinogona kusanganiswa nechirwere ichi. Asi yeuka kuti hazvisi zvese zviratidzo izvi zvinoshanda kune wese munhu.
| Hunhu hwemuviri | Tsananguro iri nyore |

Sezvambotaurwa, kureba kupfuura avhareji ndicho chinhu chinonyanya kuonekwa pakati pevanhu ava. Tsvagiridzo yakawana kuti vanhu ava vane kopi yeimwe jini reSHOX pamachromosomes edu ebonde, izvo zvinokonzera kukura kwemapfupa nekukurumidza, kunyanya mumakumbo.
Varume vazhinji vane chirwere cheXYY vane kukura kwepabonde kwakajairika uye mazinga e testosterone , saka vanokwanisa kubereka vana. Zvisinei, varume vashoma vanogona kusangana nematambudziko ekubereka.
Ndezvipi zviratidzo zvine chekuita nechirwere ichi?
Chirwere cheXYY chinogona kusanganiswa nezvimwe zvirwere uye matambudziko ekudzidza. Zvisinei, hunhu hwezviratidzo izvi hunosiyana zvikuru kubva kumunhu kusvika kumunhu. Kunyange hazvo vamwe vangazviona zvishoma, vamwe vangangobatwa zvakanyanya.

Heino chimwe chinhu chatinofanira kuyeuka tese: Kuremara kwepfungwa .Kuremara kwepfungwa hakusi chinhu chinowanzoitika muXYY syndrome. Hungwaru hwevana ava hunowanzova pakati pehuwandu hwakajairika.
Chirwere cheXYY chinoonekwa sei?
Dambudziko iri rinogona kuonekwa kuburikidza nekuongororwa kwakaitwa mwana asati aberekwa, kureva panguva yekuzvitakura , pamwe nekuongororwa kwakaitwa pazera ripi zvaro mushure mekuzvarwa.
- Munguva yekuzvitakura: Chirwere ichi chinogona kuonekwa kuburikidza nekuongororwa kwemajini kwakakosha kwakadai seAmniocentesis kana Chorionic Villus Sampling kunoitwa paamai vane pamuviri.
- Mushure mekuzvarwa: Kuongororwa kwekaryotype kunowanzoitwa. Uku kuongororwa kweropa kuri nyore. Kunogona kuona nemazvo huwandu hwemachromosomes ari mumasero edu uye kurongeka kwawo.
Kana chirwere ichi chaonekwa, kana mwana wako akanonoka kutaura kana kuti akanonoka kufambisa nhengo dzemuviri, mishonga yakakosha uye rutsigiro rwedzidzo zvinogona kubatsira. Taura nachiremba wako nezveizvi uye, kana zvichidikanwa, mutumire kuna chiremba wevana, nyanzvi yezvemajini, kana nyanzvi yekukura.
Kutaura zvazviri, varume vazhinji vane XYY syndrome pasi rose vanorarama hupenyu hwavo hwese vasingazive. Izvi zvinokonzerwa nekuti havana zviratidzo zvinoonekwa.
Mharidzo Yekuenda Nayo Kumba
- XYY syndrome chirwere chinokonzerwa nemajini chinoitika zvisina tsarukano. Hachikonzerwi nemhosva yemubereki kana kuti chinogara nhaka kubva kuchizvarwa kuenda kune chimwe.
- Vakomana nevakuru vazhinji vanorarama hupenyu hwakanaka, hwakajairika vasina zviratidzo kana zviratidzo zvishoma.
- Chinhu chinonyanya kuzivikanwa ndechekuti munhu akareba kupfuura avhareji.
- Dambudziko iri hariwanzo kukonzera kushaya pfungwa.
- Kana mwana aine matambudziko akadai sekunonoka kutaura kana kukura kwemuviri wake, kuzivikanwa nekukurumidza uye kurapwa kwakakodzera pamwe nerutsigiro zvinogona kuita mutsauko mukuru. Taura nachiremba wako nezvechero zvinomunetsa.
