Ubomi obubini buvela njani?
Iimbini zi-mono- ne-dizygotic. Iyokuqala njengamaconsi amabini amanzi afana kunye kunye nokuphuhlisa xa ukwahlula iqanda elinye, utyalwa ngumntu ofanayo. Zobabini iintsholongwane zitholakala kwisitya esisodwa esisodwa kunye neeplascent enye. Lawa mawele aphela ngesini esifanayo, kwaye amaninzi amakhwenkwe.
Amawele e-Dizygotic, okanye amawele, avela ngokuchumisa amaqanda amabini nge-spermatozoa. Ngaphezu koko, ukukhulelwa akusoloko kusenzeka ngosuku olunye kwaye elinye lamamawele lingaba luninzi lweentsuku kunomnye. Iiseli ze-Egg zinokuba zivela kwi-ovary enye okanye zivela ezimbini. Ukukhulelwa okunjalo kubonakala kunqabile kwaye kwenzeka kuphela kwi-2% yamatyala. Ukukhulelwa ukusuka ekukhulelweni kwaye kuze kube yilapho ukuzalwa kweso sibini kudla ngokuxhamla iingxaki ezininzi.
Akuyena wonke umntu owaziyo, kodwa ekubeni lolu hlobo lophando lubonakala, njenge-ultrasound, kwakunokwenzeka ukufumanisa ukuba ukukhulelwa okuphindwe kabini kudla ngokuphindaphindiweyo kunokuzalwa okufanayo . Okokuthi, umfazi ukhulelwa ezimbini iintsana, kodwa kwinqanaba lokuqala lophuhliso (ngokuqhelekileyo kwi-trimester yokuqala) enye yezi zibini ziyeka ukukhula kwaye kuphela umntwana omnye ozelweyo.
Oku kunokumiselwa xa uviwo luqhutywa kwiiveki ezi-5-8 nangemva kwexesha kwakhona. I-ultrasound yokuqala ibonakalisa ngokucacileyo amaqanda amabini e-fetal, kwaye enye, okanye iyanyamalala ngokupheleleyo, okanye iyayeka ukuphuhliswa. Ukuphuhliswa komntwana wesibini ukususela ekukhulelweni kwaze kwaba sekuzalweni kwenzeka ngokubhekiselele kwimeko yokukhulelwa omnye.
Iingxaki zokukhulelwa ezininzi
Iintlanzi, okanye iwele ze-dizygotic ezine-blister ezahlukeneyo ze-fetal kunye ne-placenta, azixhomekeke kwenye kunye kwaye aziphazamisi nophuhliso. Kodwa, ngokwenene, umama, obenomdla ophindwe kabini, unzima kabini kunzima xa ukhulelwe. I-Toxicosis, ukukhukhumeza, ukugqithisa ngokweqile, isifo kunye neengxaki zesibindi kunqobile loo mfazi okhulelweyo kabini ngokuphindaphindiweyo, kwaye ubomi bokusulelwa kumama ukuya ekuzalweni kweintsana kunzima, kwaye ngamanye amaxesha kunomngcipheko kwimpilo kamama.
Kwimeko efanayo ukulinda umama wamawele angama-monozygotic. Kodwa apha, ngaphezu kweengxaki zokuthwala, ubunzima buvela ngokuphuhliswa kwesinye sezibini. Njengomthetho, umahluko phakathi kwesantya phakathi kwabancinci kufinyelela kwisikhilomitha esinye nesiqingatha, xa umntwana omncinci egqithisa emva kwazo zonke izikhombisi ukusuka kumdala.
Oku kubangelwa ukuba iintsana ezisuka kwelinye i-placenta zondla, kwaye lowo uthatha ubuninzi bezondlo kakhulu. Ukongezelela, kukho umxholo wento ebizwa ngokuba ngumnikelo, xa elinye lamawele liqala ukondla kwaye likhule ngexabiso lentlawulo yesibini.
