Kodominirovanie - keia mea he hana ano o ka AaOIeIOUIeXAOAaIN ma waena o alleles

No ka maopopo i ua kodominirovanie ma aaiaoe?, Ke kālailai i ka hiki ke ano o ka AaOIeIOUIeXAOAaIN ma waena o alleles. E like me ke kuhiakau gametes maemae hou Gregor Mendel, i ke kahua o ka gametes i loko o ka mea misses e kekahi o na alleles elua o kēlā me kēia makua meaola kuleana no ka moʻolelo. Pela, ma ka maʻamau diploid gamete hanaʻia, ke kau o ka alleles. Eia, huina domination ke hoike mai ai ia ia iho i loko o ka AaOIeIOUIeXAOAaIN ka wā Hoʻohaku uhi recessive, kāpili dominance a me ka kodominirovanie.

kāpili dominance

Ma keia hihia i ka Hoʻohaku allele mea,ʻaʻole loa suppresses recessive, i ka hopena o ka hou waena hiʻona. A hoohalike kaulana mea kāpili dominance pua kala like 'ole o kekahi mau pua e like me cosmos. Ina he mea heʻulaʻula pua homozygous genotype (AA) (akaka laina) a me keʻokeʻo pua (Aa), ka mea maemae laina. Ia laua i hele hōʻike pua me a pink 'ia nā pōpō - laʻana kodominirovaniya. Lākou genotype Aa i ka palapala, akā, i Hoʻohaku a recessive alleleʻikeʻia. By i kela kapa huli ma waena o - a pink waihoʻoluʻu.

Kodominirovanie

Kekahiʻano o ka'ōewe 'aoʻao - kodominirovanie. O kŰia mea i 'ano like me ka mea kāpili dominance, akā, no ka mea, hoʻokahi nui like. Kodominirovanie -'ōewe AaOIeIOUIeXAOAaIN ma i ku pono ana i na hoailona i hoʻomaka ai ka poʻe, akā, e hui pu ole ai me ka mai ole paka i ka palapala hiʻona.

I ka wa e holo i ke keʻokeʻo pua me kaʻulaʻula petunias ke huli ulaula, a pink, keʻokeʻo aʻelua-waihoʻoluʻu. Flower me kaʻulaʻula, a keʻokeʻo ka hahau ana o ka hopena o ke kaʻina hana e like me kodominirovanie. He ka loa, he pono ole mamuli o ia ka AaOIeIOUIeXAOAaIN.

Kodominirovanie ano o nā mea kanu.

AaOIeIOUIeXAOAaIN nonallelic nā'ōewe

Ua ua olelo mai ia wale ka allelic nā'ōewe pili manaÿo e like me ka piha dominance, kāpili dominance a me ka kodominirovanie. Ano he kumu hoʻohālike, a ho okolohua lehulehu ua hookupaa iho la ia ia ma ka hihia o ka ole-allelic nā'ōewe haawiia i nāʻano o nā hana kūleʻa - alu like 'ana, epistasis, complementarity pīlali. Lakou i mea hoike o ka pīlali, ma mua kāpili dominance, o ka'āina hoʻoili o kekahi kanaka o ka ili waihoʻoluʻu.

Kodominirovanie i kānaka

Kekahi poe noonoo ole akā, hahau hoʻohālike kodominirovaniya - hooilina o ke koko pūʻulu. E like me oe i ike, he mea eha koko pūʻulu. Ka mua hui G (I) ua hoike ia ma ke alo o nā genotype homozygous recessive nā'ōewe O. A lua o ka pūʻulu (II) kānāwai, a me ka genotype AB ole AA. Ke phenotype pela, e hoike wale A Hoʻohaku'ōewe, a pau loa suppresses he recessive'ōewe. A like kulana home 'ole e ia no ke kolu o ke koko pae B (III), a ua hanaʻia me ka genotype BB a he VO. Hoʻohaku'ōewe i loko o ka recessive'ōewe suppresses O, a hoike mai ai ia ia iho e like me ka hopena o ka piha dominance. Akā, mea, e hiki mai ka wā i kela kapa me ka homozygous genotypes AA, a BB? A me ka'ōewe A a me B'ōewe i Hoʻohaku, no laila, i kekahi o ia mau mea hiki ole loa uhi i ka 'ē aʻe, a e hoike ana ia lakou iho. Ma keia hihia, me ka 100% pahiki e hā o ke koko pae - AB paa kodominirovanie. Kēia ka hana i loko o ka i kela kapa heterozygous Ao, a bo, ma kekahi hopena mea hiki:

P: AOhVO;

F1: Ao (II), AB (IV), VO (III), PA (I).

Ia mea ke kumu i ke keiki i ka koko pae hiki ole ia i ka hookahi koko pae ana o na makua. Ke kumu hōʻike i kodominirovanie ua hoikea mai oia, i wale i loko o ka waihoʻoluʻu o ka mea kanu.

Kodominorovanie a mutation

Ua Ua stipulated i ka hōʻike o nā kailaʻae - keia mea,ʻaʻole mau kodominirovanie. Kēia proves pohihihi keia aaiaoe hiʻona i kānaka a me kekahi mau holoholona - heterochromia (waihoʻoluʻu OOAaAeAa iris). Heterochromia Ua piha, no kekahi laʻana, ka wāʻeleʻele maka i kekahi a me kekahi uliuli, a me ka helehelena, no ka mea hoike i ka wa a ka mea uliuli iwi i ke oho Hoʻohana. Heterochromia, hoʻowahāwahā i ka nohoaliʻi analogy me ka waihoʻoluʻu a pau pena, he kumu hoohalike i kodominirovaniya a genomic mutations. Kue o ka ili pigmentation - kekahi kodominirovanie mea aaiaoe? Nei. Kodominirovanie ma keia hihia i hookahuli ai me ka maʻi.

Kodominirovanie ka mua kānāwai Mendel

Kodominirovaniya kŰia a kāpili dominance, ma mua kilohi, paipai i ka mua kānāwai o Mendel ma ka uniformity o hybrids ua i hana. me peas, i ka mea e mālama i kekahi kodominirovanie a hapa dominance, a wale piha dominance Gregor Mendel i loko o kona mau ho okolohua hana. Ma na wahi he poʻe'ē he hoailona, a me ka mea i ka wā hoʻokahi 'ia o ka hiki ole, ke mau hua'ōlelo ua loa pono. Ma hope o aneane he kenekulia, ia mea, i hoʻokolokolo kodominirovanie, a kāpili dominance, i hoololiia ke kānāwai mua, e hoakaka ana i ka lua o ka hanauna o hybrids hou, ma ke kumu o'ālike homozygotes ma ka aoao o ka mua o ka hanauna hybrids me ke alo o na hoailona a me. Eia kahi mea akaka Hoʻohaku i loko o ka hihia o ka piha dominance a hui hoailona - ma ka hihia o ke kāpili dominance.

Hiki nō ke hoʻohana i ke kumu hoohalike o ka'āina hoʻoili o ka koko pūʻulu e ÷ ike i ka pololei hoʻokō ana o ke kānāwai mua o Mendel:

P: AA BB ×;

F1: AB, AB, AB, AB.

Ka hopena o ka holo laina elua e e heterozygous maʻemaʻe specimen, ma a ka poʻe'ē he phenotype hoike hoailona, e like me ia lŘlŘ kodominirovanie. Ua hoʻopili like me ka hoololi.
