Pehea hana aaiaoe oko

Mutations 'ia i loko o ke kino, e alakai ana i ke kahua o kekahi mau abnormalities. Ke kaumaha ma muli ma i keena, a ma ka kahua me ka mea ana, i ka aaiaoe mea oko a hiki i hoʻomaka ai, a laila, pū i hiki ia loli, i ukali ia e hereditary keena. Loli i malalo iho i kekahi mau hiʻona o ke kino, ke kaumaha ma muli o ka genotype. Ka mea, e hoomau ana no kekahi mau hanauna, a ma kekahi mau hihia he mea i hoʻomāhuahua o ia deviations.

Aaiaoe oko a hiki e hoike i kekahi loli 'i mea nui kupono e koke hōʻike iā lākou. Albinism meaola mea he laʻana o mutations a aaiaoe loliʻaneʻi hiki e wahi i ka nele o ka hulu melemele, a me kona mau pepeiao, ma Style a me nā like hiʻona. Ke kanu like kŰia kekahi hana - i ke ku ei ka nui like 'ole o ka petals a kanu kiʻekiʻe, nā ahuwale abnormalities. A pau keia mea heʻilihune o mutations, a me loko o ka manaʻo o ka ili loli i loko o ka meaola.

maomeka o ka ho okumu

Ma kekahi pūʻulu o nā kanaka i coexist loko i kekahi kōā o ka manawa, i hana i kekahi noho'na makaainana i ulu mutation. Ka mea, i hui ma huikau ma luna o ka muli o nei hereditary kāna moʻolelo. I ka nui o ka haiahū kūmau, ka mea i oi aku ka likelihood o ka muli o nā loli hou i hou deviate mai ke kūmau.

Mutations hana ana i ke kahua o ke keena. I ka anu u gamete kuʻi nukeliu'ōewe recombination i, i mea no ka papa kuhikuhiE kumu o ka variability. Ke kumu paha e ka chromosome a huikau ka hoʻohui pū i meiosis a me ka fertilization. No ka mea, o na hoikeana i keia kakahiaka nui ke kahua me ua hanaʻia e aaiaoe oko a.

Naʻe, i ka mutation hana ole spontaneously paha accidentally i hoʻomaka ai, ka mea, e ku pono ana i ka aoao o kekahi mau aʻe. Mutagen i e ka pāhawewe waiū, liluwelo a mea hoʻomaʻi hopena Nine Inch.

Inā ka halepaahao ma i ka mutation ana, i hoopaa mai ai i ke akamai, e paʻi, e hoʻoneʻe 'ia paha i aaiaoe oko a ua hana. Loli hiki e'ōewe, genomic paha chromosomal ke kaumaha ma muli kahi e hōʻike.

Mutations ma evolution

Aaiaoe oko a ma ka evolution i ka na hiohiona ia ma luna o ke kino. Kona waiwai nui kūpono nui, a me ka mea mua manawa keia kŰia a me kona maomeka hoomaka e e? Anoee ma ka 18th kenekulia.

Charles Darwin mai la i na meaola mea malalo iho o ke kanaka oko a. Kona papa kuhikuhiE ano kapa aku la ia i ka ulia, ka hoahanau rarity a me ka 'ole-directional ma ka ano. Kēia me ka nui loa complicates ho'āʻo e wńnana i ke kaʻina hana 'ole kekahi wānana.

Eia naʻe, i alakaʻi i ka mutation a hiki i ke kahua o kekahi me ke koe o aaiaoe oko, i ke kahua o kekahi genotypes. Naʻe, i loko o ke ano o ia i kekahi kuleana pili iʻano nui hanaʻia combinative variability - ma ka moe nā'ōlelo lŘlŘ recombination o chromosomes. Kēia EUIAaIN ka hoʻokaulike o nā'ōewe a me kā lākou mau hana kūleʻa ma ka genotype, akā, na nā'ōewe lakou iho mai mai hoʻololi i, nolaila, aohe mea nana e abnormality.

Mau keʻano o ka hanaʻana kōkua i maopopo maikaʻi pehea aaiaoe oko a me nā loli. Mai ka wahi o ka Hawaii o ka evolution e nui kanakaʻokoʻa. I ka wa e hele mai i ka hoike ana o hereditary loli, ka mea lawe i ka helu ole wale i ke alo o'āno'ē nā'ōewe, akā, me ko lakou hui pu ana, a me nā nā'ōewe pili ana i ka genotype, ma ka hou, i, ma kekahi aoao a me kekahi, he aha ka mea i ka? Aneie rula, a me ka pololei? Acaeoey o ka meaola.

Ma ka kekahi lima, ia mea pono pololei EYI o aaiaoe mea mai kekahi hanauna aku i kekahi, akā, ma ka 'ē aʻe lima, mālama o ka' ike i loko o na na nā'ōewe hiki e loa nā palapala i ka meaola.
