Ua manaʻo mua paha kekahi mau wahine e loaʻa i nā keikikāne a ʻoi aku paha nā kaikamahine?

Hoʻopili ʻia ke kāne o ka pēpē e nā genetics, a ua ʻike ʻia nā haʻawina e pili ana nā hemahema chromosomal i ke kāne o ke keiki hānau hou.

ʻOi aku ka manaʻo o ka hopena i nā kāne.

I loko o nā mammals, nā sperms e lawe ana i ka X chromosome e hana i nā kaikamāhine aʻo nā sperms e lawe ana i ka Y e hana i nā keikikāne. No laila, ʻo nā mākua i loaʻa nā kīnā genetic i X a i ʻole Y e hana i ka wahine ʻē.
Hōʻike nā haʻawina e hana nā makua kāne keʻokeʻo ma kahi o 105 mau keikikāne no kēlā me kēia kaikamahine 100, hana nā makua kāne ʻApelika ma kahi o 103, aʻo nā makua kāne kahiko e hoʻonui i nā kaikamahine.

Loaʻa nā hopena ʻē aʻe, no ka laʻana, ʻoi aku ka nui o nā keikikāne me ka maʻi hepa C.
ʻO ke ʻano, kokoke i nā wahine a pau e ʻoi aku ka nui o nā keikikāne - ʻo ka male kāne o 105 mau keikikāne a 100 mau kaikamahine e hoʻopilikia ʻia e ka koho hoa, e loaʻa kahi ʻano genetic.

No laila, manaʻo paha mākou i nā hopena genetic i nā wahine pū kekahi, ʻoiai nāwaliwali.
