Aaiaoe 'ike: recessive a me ka Hoʻohaku nā'ōewe

He aha mea he'ōewe?

'ōewe - he hoakaka kaʻina o nā nucleotides dezoksiribonuklinovoyʻakika ma i ka encoded aaiaoe ike ( 'ike no ka iniiaiie' ole o ke kumuʻiʻo nā lātoma). DNA lātoma - kaulua ili. Kēlā me kēia o na kaulahao mai he mau 'nucleotide kaʻina. Ke iniiaiie 'ole o ke kumuʻiʻo, i mea ka helu a me ka kaʻina o'amino nāʻakika, Radio he kuleana kūlana ma hereditary kāna moʻolelo. E encode 'ike pono a me ka heluhelu mau, pono i ka'ōewe i hoʻomaka ai codon, hoopau wale codon a me ka naʻauao lākou codons pololei encode i ka makemake'aminoʻakika kaʻina. Codons hoolilo Kime Poʻokela nucleotides i encode he ua 'aminoʻakika. Codons UAA, UAG, UGA i ka ipu, a hana ole code for Na kekahi o na? Ueony'amino nāʻakika, ka replication kaʻina heluhelu ka wā e hoʻi i kāpiliʻia. Ka i koe, codons (i loko o ka nui o ka 61 na apana) encode'amino nāʻakika.

Līkaia no ka Hoʻohaku a me ka recessive nā'ōewe. Hoʻohaku'ōewe - he kaʻina o nā nucleotides a hāʻawi aku i ke kīnā o ka ua hiʻona (nānā 'ole o ka' ano o nā'ōewe mea i loko o ka ia mau (Ua haawiia recessive ole Hoʻohaku'ōewe)). Ke recessive'ōewe mea he nucleotide kaʻina, a ma olelo o ka phenotype hiʻona mea hiki wale nō i loko o ke alo o ka paʻa o ka ia recessive'ōewe.

Oia 'ike e wale aaiaoe ikepili i hiki ke pū i hiki mai ia hanauna aku ia hanauna aku. Eia naʻe, wale i kekahi hui malu pu ana o ka'ōewe Lolina hilinaʻi nui olelo o ka moʻolelo. Inā ka mau mea recessive a me ka Hoʻohaku'ōewe, ka mea e hōʻike phenotypically waiwai encoded Hoʻohaku. A hoike wale kā lākou 'ike i loko o hihia o ka pu ana o ka elua recessive nā'ōewe. Ia mea, i ka Hoʻohaku'ōewe suppresses recessive.

Kahi loaʻa nō nā'ōewe?

Information mea mākou e lawe aku nā'ōewe hele mai, mai nā kūpuna o kākou. Mau nā makua ole wale akā, i mau kūpuna a me nā hoahānau pili koko. Kanaka'ōewe 'ia paha ua hanaʻia ma ka huina o ka sperm a me ka hua manu, a he oiaio, ua - ka wā merging X a me Y chromosomes a mau X chromosomes. Mai ka makua kāne ke lawe 'ike i nā X a me Y chromosome, oiai, mai kona makuwahine - wale i ka X chromosome.

Ua ua ike ia ka X chromosome kekahi 'ike hou aku no laila, na wahine i oi hoʻopale i ka maʻi o kekahi ano ma mua o ke kane heluna. I kumumanaʻo, ka helu o ke keiki kāne a me nā kaikamāhine e e like, akā, ma ka hana, i nā keiki i hānau. E like me ka hopena, ma ka muli o kēia mau kūʻiʻo, aia no he o hoʻonupaikini na sexes elua. Kiekie fertility o ke kane heluna kanaka ua compensated ma ka ia'ku kiekie ae i ka likeʻole ololi, ano o na wahine.

aaiaoe 'enekinia,

Currently ua alakai nui haʻawina o ka aaiaoe mea. Ke ki ina hana like o ka hoʻokaʻawale, a me ka cloning o kanaka nā'ōewe hybridization. Keia mea - o ka nui loa ka anu u ma ka pili ana i ka wā e hiki mai. Oia noonoo i keia mea hilo i hoʻonāukiuki aku i ka puu o ka speculation a me ka 'upu'. he piha like ma hope e hiki ai na kanaka e hoʻolālā i ka waiwai a me nā hiʻona o ka kekahi hanauna, e pale aku i na mai he nui loa, a me nā loko ulu a me kā lākou mau nenoai no transplantation.
