Kodi mapasa achifumu amatanthawuza - chinsinsi cha chirengedwe, kapena mphatso ya tsoka kwa makolo osankhidwa? Kodi zingakhale zovuta kwambiri? Inde, awiri ofanana kunja, koma pa nthawi yomweyo kugonana kosagwirizana - mwana wamkazi ndi mwana wamng'ono - ichi ndi chimwemwe chenicheni. Koma pa nthawi yomweyi - udindo waukulu, ndipo ngati muwonjezera chiopsezo cha mitundu yosiyana siyana, zingakhale zabwino kuti awiri awiriwa azikumana chimodzi mwa chikwi.

Malingana ndi chiwerengero, ana awiri amapasa ali mnyamata ndi mtsikana - chinthu chosavuta kwambiri kuti atatha kuphunzira za mimba yambiri, amayi ambiri ndi abambo, komanso madokotala, ndipo musaganize kuti mapasa achifumu angabadwe . Ndipotu, ana osabereka, kaŵirikaŵiri amakhala chifukwa cha umuna wa mazira awiri, ndiwo mapasa, koma osati mapasa. Ngakhale zili choncho, nkhani ndizochitika pomwe panthawi yomweyo kuwala kunkaonekera mbale ndi mlongo, mofanana ndi madontho awiri a madzi.

Momwemonso ndi mapasa, kapena mapasa omwewo, mwana wamwamuna ndi mtsikana wobadwira ali ndi pafupifupi ofanana ndi majini? Tiyeni tiyesere kuzilingalira.

Kodi mnyamata ndi mtsikana yemweyo angakhale mapasa?

Ndizosatheka kukana mfundo imeneyi, ndipo pang'ono pang'onopang'ono yatulutsa ndi sayansi ya kubadwa kodabwitsa kwa mapasa osagonana. Inde, zingakhale, ngakhale zovuta kwambiri.

Tonsefe timadziwa kuchokera ku maphunziro a thupi kuti mapasa amachokera ku zygote imodzi ndipo amakhala ndi chromosome yomweyo. Koma pali zifukwa zingapo komanso zosawerengeka zomwe amapasa amaonekera: mnyamata ndi mtsikana. Tiyeni tione ngati n'zotheka:

4. Ngati dzira (dzira lokha ndi thupi lake) ndilopangidwa ndi maselo awiri. Zikatero, makanda amabadwa athanzi, opanda ma gene anomalies.

Kodi mungakonde bwanji mapasa a mnyamata ndi mtsikana?

Ntchito yopanga monozygotic heterozygous mapasa ndi yovuta kwambiri ndipo sinaphunzire bwino. Choncho, ngati kuti makolo sakufuna kubereka mapasa a mwanayo ndi mtsikanayo, nkovuta kuthetsa kapena kusokoneza njirayi pasadakhale. Ngakhale kuti sayansi siimaima, ndipo pamodzi ndi kukhazikitsa kwakukulu kwa IVF, amayi amtsogolo ndi abambo ali ndi chiyembekezo m'tsogolomu kuti athetsere chikhalidwe cha ana ndi chidziwitso chawo.
