By’olina okumanya ku bika by’abalongo

Ennaku zino okuzaala abalongo kusingako katono okusinga edda. Mpozzi olina abalongo mu maka go oba mu mikwano gyo. Bw’okizuula nti olina abalongo, owulira essanyu lingi ate ng’oyagala okumanya okutono. Kumpi buli muntu amanyi ku balongo abafaanagana n’abalongo ab’obwasseruganda bokka. Naye mu butuufu waliwo ebisingawo emabega w’ebika bino ebibiri. Okay, ka twogere ku nsi ey’ekitalo ey’abalongo mu ngeri ennyangu.

Engeri enkulu ebbiri ez’okufunyisa abalongo olubuto

Waliwo engeri bbiri enkulu abalongo gye bayinza okufumbirwamu olubuto. Abasawo bino babiyita ``Dizygotic'' ne ``Monozygotic''. Mu nnimi z’abantu aba bulijjo, bano balongo abalabika mu ngeri ey’enjawulo ate abalongo abalabika mu ngeri y’emu.

• Fraternal/Dizygotic twins: Kino kibaawo ng’amagi abiri gafulumye okuva mu nkwaso za maama mu kiseera kye kimu ne gazaalibwa ensigo bbiri ez’enjawulo okuva ku taata. Mu ngeri endala, kiringa endowooza bbiri ezibeerawo mu kiseera kye kimu.
• Identical/Monozygotic twins: Kino kye kiseera eggi erimu, erizaaliddwa ensigo emu, bwe lyawukana mu bibiri mu wiiki ezisooka ng’efunye olubuto . Kino kiri bwe kityo kubanga abalongo bombi balabika nga bafaanagana kubanga embuto emu eyawukana mu bibiri.

Mu kiseera kino, obujjanjabi bw’okuzaala naddala tekinologiya nga IVF oluusi busobola okuvaako abalongo abaawukana katono ku nkola zino ez’ekinnansi. Abasawo bino babiyita "atypical twinning." Bino bitono nnyo.

Bano abalongo abafaanagana be baani? (Amalongo agayitibwa Monozygotic Twins) .

Bano be "identical twins" ffenna be tumanyi. Nga kimu kya kusatu ku balongo bonna mu nsi be ba kika kino.

Nga bwe nnagambye emabegako, abaana bano batondebwa olw’okuzaala eggi erimu ensigo emu, olwo embuto n’eyawukana mu bibiri. N’olwekyo, amawulire gaabwe ag’obuzaale, kwe kugamba, `DNA` yaabwe, gafaanagana 100% . Eno y’ensonga lwaki balabika era bawulira kye kimu.

Oluusi abalongo bano basobola okugabana ensawo y’omu lubuto y’emu mu lubuto. Kino kitegerekeka mu kiseera embuto we yayawukana. Ekirala ekyewuunyisa nti abalongo abamu abafaanagana balinga "ebifaananyi eby'endabirwamu." Kwe kugamba, ekiri ku ludda olwa ddyo olw’omwana omu kye kimu n’ekyo ku ludda olwa kkono olw’omwana omulala. Ng’ekyokulabirako, omu bw’aba wa mukono ogwa ddyo, omulala ayinza okuba ow’omukono ogwa kkono. Mu butuufu, lwaki embuto efumbiddwa eyawukana mu bibiri, kikyali kyama eri eddagala.

Ate abalongo abalabika mu ngeri ey’enjawulo? (Amabaale agakola dizygotic) .

Kino kye kika ky’abalongo ekisinga okubeerawo. Ebitundu nga bibiri ku bisatu eby’abalongo bonna ba kika kino. Era tubayita "Fraternal twins ".

Wano amagi abiri ag’enjawulo we gazaalibwa ensigo bbiri ez’enjawulo. N’olwekyo, abaana bano balina ebitundu 50% byokka ku mawulire g’obuzaale (DNA) ge gamu. Mu butuufu, balinga baganda babiri aba bulijjo abazaalibwa mu biseera eby’enjawulo .

Olw’ensonga eno,

• Tebalina kulabika kye kimu.
• Tebalina na kuba na kikula kimu. Kwe kugamba, bwe wabaawo abalongo abawala n'omulenzi , mazima ddala ba ``Dizygotic`` twins.
• Zirina enseke ez’enjawulo n’ensawo z’omu lubuto ez’enjawulo mu nnabaana.

Omanya otya mu bukakafu oba abalongo bafaanagana oba ba njawulo?

Kino kizibu abazadde bangi kye balina.

• Abalongo bo bwe baba bawala na mulenzi , tewali buzibu. Mazima ddala ba `` Dizygous`` oba abalongo ab'enjawulo.
• Naye bombi bwe baba ba kikula kimu , kwe kugamba, bombi balenzi oba bawala, emboozi eba nzibu katono.

Okukebera amaloboozi aga ‘Ultrasound’ ng’oli lubuto naddala oluvannyuma lwa wiiki 14, kisobola okuwa abasawo endowooza ku nnabaana y’omwana. Naye si bituufu 100%.

Oluusi, abalongo bwe bazaalibwa, batunuulira enseke ne bagamba nti, "Bano balongo bafaanagana," naye abalongo bwe bakula, batandika okulabika mu ngeri ey'enjawulo. Era kiyinza okuba eky’enjawulo. Kale, bwoba oyagala okumanya mu butuufu, ekisinga obulungi kwe kukeberebwa `DNA`.

Ebika by’amabaale ebitali bimu nnyo ebyewuunyisa okuwulira

Oboolyawo bino tobiwulirangako na kubanga bitono nnyo nnyo.

• Semi-identical twins `(Sesquizygotic)`: Kino kibaawo ng’eggi erimu lifumbiddwa ensigo bbiri. Kino tekitera kubaawo nnyo, kubanga mu budde obwabulijjo tewali nkwaso ezikoleddwa mu ngeri eno ziwangaala. Abaana bano basobola okuba nga wakati wa 50% ne 100% ku DNA yaabwe efaanagana. Ekyewuunyisa nti ebika by’abalongo bino nabyo bisobola okuba eby’ekikula eky’enjawulo.
• Vanishing Twin Syndrome: Mu butuufu kino si kika kya balongo, wabula kintu ekibaawo ng’oli lubuto. Abalongo babiri bwe bafuna embuto, omu ku lubuto alekera awo okukula n’ayingira mu mubiri gwa maama oba mu lubuto omulala.
• Fetus-in-fetu: Kino kitegeeza "fetus mu lubuto." Eno embeera ya parasitic twin. Omwana w’amabaale omulala atakula asangibwa munda mu mubiri gw’omwana omulamu obulungi. Kino nakyo tekitera kubaawo nnyo.
• Superfetation ne Superfecundation: Bino nabyo bitera nnyo okubeerawo. `Superfetation` kwe kubeerawo kw'olubuto olulala ng'omukazi yafuna dda olubuto. `Superfecundation` kwe kuzaala amagi abiri agafulumizibwa mu kiseera kye kimu eky’okuzaala ensigo okuva mu basajja babiri ab’enjawulo. Bingi ebikyazuulibwa mu bya ssaayansi ku bino.

Tofaayo ku bika bino ebitali bimu. Kubanga emikisa gya bino okubaawo mitono nnyo. Ebiseera ebisinga, tusanga abalongo ab’ebika ebikulu ebibiri bye twayogeddeko emabegako.
