ʻO nā kumu no ka hānauʻana o nā māhoe

I kekahi mau haneli i hala aku nei, uaʻikeʻia ka hānauʻana oʻelua keiki aʻoi aku paha o ka wahine ma keʻano he mea kupanaha, akā i kēia mau lā uaʻike nā kauka i kēia ho'ākākaʻana he nui nā ho'ākāka.

ʻO nā kumu o ka hānauʻana o nā māhoe penei:

1. No ka mea, ma 10% o nā hihia, e puka mai nā pēpē ma nāʻohana i hānau muaʻia nā māhoe. Ma kēiaʻano, hiki ke ho'ākākaʻia nā mea a pau ma ka predisposition genetic, e like me ka wahine e hana mai ai he nui o nā hormones, kahi e hoʻoulu ai i ka nui o nā hua i ka manawa hoʻokahi, a ma laila e hoʻonui i ka likelika o ka hoʻonuiʻana i nā pēpē i ka manawa hoʻokahi.
2. ʻO ka hoʻopauʻiaʻana o nā lapaʻau waha i hikiʻole ai i ka'ōwiliʻana a me ka hoʻopauʻana o ka mahina i nā pūnaewele wahine ke alakaʻi pinepine i ka hoʻokuʻuʻana o nā pūnaewele i ka manawa hoʻokahi, i ka malama mua, e like me ka ho'āʻoʻana o ke kino e "hopu".
3. Hanaʻia o ka uluʻole me nā lāʻau lapaʻau e hoʻonāukiuki i ka'ōwiliʻana, hāʻawiʻia ka hopena like.
4. I ka hoʻohanaʻana i ka fertilization in vitro, ua "kanu" nuiʻia nā wāhine i kekahi manawa i mea e hoʻonui ai i nā kūlana o ka'ōpū, a hiki i ka hopena o ka hoʻomakaʻana o kēia mau embryos e ulu pono i loko o ka pūpū.
5. ʻO nā hiʻohiʻona kino o ka makuahine,ʻo ia hoʻi, ka bifurcation o ka'ōpū, hiki ke alakaʻi i ka manaʻo o nā māhoe.
6. ʻO ka makahiki o ka makuahine,ʻo ia ka makua,ʻo ia ka nui o ka hānauʻana i nā māhoe.
7. Hoʻouka hou aku, no ka mea,ʻo kēlā me kēia hāpai hou ka hopena i ka hānauʻana o nā māhoe. Inā hānau mua kahi wahine iʻelua mau keiki, a laila ua pāluaʻia kēia proba.

Eia hou,ʻo nā haʻawina e hōʻike ana i ka wā o nā kaua a me nā wā pōpilikia i ke ola, piʻi ka laulima o ka hānauʻana o nā pēpē. ʻAʻole i loaʻa i kēiaʻike he wehewehe, aʻo nā meaʻepekema wale nō ke noʻonoʻo i ka hana maʻamau o ka mālamaʻana i ka lāhui kanaka i kēiaʻano.

Hiki keʻikeʻia he mau kumu no ia i hiki ke hoʻomaopopo i ke kumu o kaʻikeʻana o nā māhoe - e likeʻole me nā kamaliʻi,ʻo kekahi manawa kekahi o nā wāhine'ē. I ka manawa hoʻokahi,ʻaʻole i hiki i kaʻikeʻepekema ke wehewehe i ke kumu i hānauʻia ai nā keiki like loa (ʻo nā māhoe maoli).

He aha nā māhoe?

No laila, ma o ka hoʻopunipuniʻana o ke ao,ʻaʻole i like nā keiki i kekahi i kekahi e like meʻelua mau lelo o ka wai. Hiki iā Gemini ke lilo i dizygotic a me monozygotic, a he likeʻole kaʻano o kēlā me kēia ma keʻano o ka hoʻomohala.

Hānauʻia nā pēpē Dizygotic i ka wā e hoʻomoʻiʻia nā hua he nui i ka manawa hoʻokahi e nā spermatozoaʻano'ē, a no laila ma waho lākou a pau loa a hiki i nāʻokoʻa likeʻole.

ʻO nā kumu o keʻano o nā monozygotic (like) he mau mea kēia: hoʻokahi sperm miki hoʻokahi sperm, akā ma hope o kekahi manawa (mai 2 a 12 mau lā) ua māheleʻia ka zygote iʻelua (a kekahi manawa) mau embryos. ʻO ia ke kumu e kū like loa ai kēia mau pēpē, ma ka genetically, ma waho, a me ka wahine. Uaʻike nā kauka i kekahiʻano hoihoi, i loko o ka mea ma mua ka hoʻomakaʻana o ka māhele o ka zygote,ʻo ka keiki ma'no o nā keiki odnoyaytsevyh.

ʻO nā māhoe Siamese a me nā kumu o ko lākou helehelena

ʻO ke kumu o ka hānauʻana o nā māhoe Siamese ma kēia mau mea: i ka manawa e hoʻohuiʻia ai hoʻokahi huahua me kahi spermatozoon a ma hope aku, ma hope o ka lā 12 ma hope o ka huiʻana) iʻelua mau'āpana, hiki i ka'ōpiopio ke loaʻa ka manawa e kaʻawale ai. I kēia hihia, pili mau kekahi i kekahi me kekahi mahele o ke kino (hiki i kēia ke poʻo maʻamau, ka'ōpū, nā lālā, a me nā maka).
