Odnoyaytsevye kanye namawele e-raznoyaytsevye

Izinsana owesifazane obeletha ngenxa yokukhulelwa okubizwa ngokuthi amawele. Izingane ezinjalo zibangela isithakazelo esiqotho phakathi kontanga ngisho nabantu abadala. Phela, amacala okukhulelwa okungafani ajwayelekile kakhulu kune-singleton. Kukhona ama-odnoyaytsevyh nama-raznoyaytsevye amawele. Zibizwa nangokuthi i-monozygotic ne-dizygotic. Izinto ezihlukahlukene zithonya ukukhulelwa kwabo. Kuphawulwe ukuthi izingane ezinjalo zesilisa zizalwa kaningi.

Umehluko phakathi kwamawele afanayo nokusabalalisa

I-Monozygotes ivela ekukhanyeni, uma i-spermatozoa eningana iveza iqanda elilodwa, elihlukanisa libe ngamaminithi amabili noma ngaphezulu. Bahlakulela ngokwehlukana, bangase babe nama-placentas ajwayelekile noma ahlukene. Izingane ezinjalo zinalokhu okulandelayo:

• ziyizo zobulili obufanayo;
• ngaphandle babheka ngokuphelele;
• baneminwe yeminwe efanayo;
• baneqembu elifanayo legazi;
• ngokuvamile zifana nokuziphatha, ubumnene;
• zihlelwe izifo ezifanayo.

Konke lokhu kuchazwa ngesethi efanayo yezakhi zofuzo. Eqinisweni, bahluke ngani ngamawele afanayo kusuka ku-raznoyaytsevyh, abane-genotype ehlukile.

Kodwa kwezinye izimo, isibuko sezici ekubukeni kungenzeka. Isibonelo, enye yezingane ingahle ihambisane kahle, kanti eyesibili isokunxele. Umqondo wesifo se-dizygotic uvela kumaqanda ngabanye ahlonywe nge-spermatozoa ehlukene. Lokhu kungenzeka uma amaqanda amaningana evuthwa ngomjikelezo owodwa emzimbeni wesifazane. Kunezizathu eziningi zalokhu. Izingane zinokubonakala okuhlukile, umlingiswa, ubumnene. Kungaba imvuthu, njengeyodwa, nobulili obuhlukile. Laba bazalwane noma odadewethu abazalwa ngosuku olufanayo. I-Odnoyaytsevye amawele azalwa kancane kancane i-raznoyaytsevyh futhi yenza cishe ingxenye yesithathu yenani.
