Inenge 4 muzana yevarume nemadzimai avo vanowanzopererwa nemakumbo vane kromosome isina kukanganisa mune imwechete kana vabereki vose vanogona kudzokera mune zvekuita pamuviri, zvakare vamwe vanachiremba vanokurudzira vanaamai karyotype miedzo sechikamu chekuongorora chikonzero chacho.
Zvinetso zveChromosome zvinokonzera hafu yezvisikwa zvose zvinokanganisa . Muzviitiko zvakawanda, zvinetso zvinomuka panguva yekuumbwa kwehurosi kana mazai uye hauna nhaka kubva kuvabereki, saka izvo zvinoita kuti iwe uite pamuviri unotevera hauzovi nemugumisiro wakafanana.
Chii Chinonzi Karyotype Chiedzo?
Chiyero chekaryotype haisi kuongororwa kwakajeka kwezvose zvinokonzerwa nehutano hwehutano. Pane kudaro, muedzo unoongorora nhamba uye chimiro che chromosomes.
Masero evanhu anofanirwa kuva nemakromosomes makumi mana nematanhatu (maviri maviri), saka kuongorora karyotype kunogona kuona kusiyanisa kubva pachiverengo ichocho uye kusakanganiswa kwekromosome.
Kubva pakuona kwepamuviri, chiremba anorayira kuedza karyotype kune vanotarisira vabereki kuti vaone zvinokonzera zvinetso kana kuti mavara kubva pamuviri kuti vaone nyaya iripo mune mumwe mwana.
Parental Karyotypes uye Kuparadzaniswa Nengozi
Zvinowirirana nenyaya dzechromosome zvinosanganisa nhamba shomanana yevakaroorana vanowanzochera misoro. Chimwe chinonyanya kuitika mukati memachato aya ndechekushandura zvakakwana , zvinoreva zvikamu zvekromosomes zvakarongedzwa zvakare.
Karyotype inogonawo kuratidza mamwe maitiro ekutumira kana chirwere chinonzi chromosomal mosaicism.
Ndiani Anofanira Kuva Nematambudziko?
Vamwe, asi kwete vose, vanachiremba vanobatanidza karyotyping yevabereki sechiitiko chemuitiro kune vakaroorana avo vakave nekushaya mamiriyoni akawanda. Vamwe vanachiremba vanoshandisa kuongororwa chete kune vakaroorana vane ngozi yakawanda yekuva nemamiriro ezvinhu ane kromosome. Zvakajairika kuedza vabereki vose.
Chikonzero chakakura chinoita kuti vanachiremba vakawanda vasarayirire vabereki karyotypes nguva dzose ndechokuti kunyange kana muedzo unoona kusakanganiswa, hapana chaicho chaungaita pamusoro pacho nokuti vazhinji vakaroorana vane karyotypes vasina kukangoramba vachiedza.
IVIV Inoderedza Dambudziko Rokuroorwa?
Izvo zvinogona kurapwa muzviitiko izvi ndezvekuedza in vitro fertilization (IVF) nekutanga kugadzirisa maitiro ekuongorora mazamu. Asi kuburikidza nekushandisa kupindira hakuratidzi kuchinja maitiro ekupedzisira.
IVF inogona kukurumidzira nzira yekuve nepamuviri chaiyo, uye vamwe vanachiremba vanotsigira kushandisa iyo, asi IVF inobvumidzawo kune vakawanda vakaroorana nokuti ndeyokuti:
- invasive
- inodhura
- kazhinji isina kuvharwa nehutano inshuwarisi
Chaizvoizvo, kutsvakurudza kunoratidza kuti kuenzaniswa nevarume vakaroorana vanoshandisa IVF, vakaroorana vanoramba vachiedza pasina kupindira kune zvimwe zvakafanana (inenge inenge 68 muzana) yekupedzisira kuva nepamuviri chaiyo.
Kukosha kweKaryotype Kuedzwa
Zvichipa kuti vanachiremba vanowanzopa mazano vakaroorana vane dambudziko rekromosome rinopupurirwa kuti varambe vachiedza kuve nemimba nguva dzose, kukosha kwekuberekwa kwevabereki kwekromosome kunogona kushandiswa. Kunyange zvakadaro, vanachiremba vazhinji uye vanotarisira vabereki vanofarira kuva nemashoko akawanda sezvingagona.
Kana iwe uine muedzo uye ukawana migumisiro isingaenzaniswi, mutungamiri wenhengo dzinogona kukubatsira kuti uzive kwaunofanira kubva pano. Kune rumwe rutivi, kana mhinduro yacho yakazara, iwe uchaziva kuti hapana chirwere chechiromosome chakazivikanwa chinokonzera matambudziko ako ekuzvitakura kunobudirira.
