Tirayn Ontogenetic. Sababaha iyo qiimaha

Sidee si ay u noolaadaan qaar ka mid ah noocyada taagta daran ee xaaladaha deegaanka daran? Waayo, badbaadada ee hiddo ay dhafan farsamo ee la qabsashada, taas oo ah, ka beddeli guryaha ku hoos tallaabo oo ka mid ah ciidamada dabiiciga ah, sida heerkulka, dabaysha, qorraxda.

Barnaamijku wuxuu hidde go'aamiso formation of balanbaalis ka kalluunka chrysalis iyo qof weyn oo ka horumarinta ukunta yar. Inta lagu guda jiro this horumarinta dheer oo dhan qoomiyadda iyo arrimo exogenous saamayn doonto phenotype shakhsiga.

Tani waxay ku kala duwan horumarineed. Tusaale ahaan waxa ka mid ah waa dhamaadka lahayn ee dabiiciga ah. Waxa xiiso leh in la fahmo sida diyaarin qabsashada.

Tirayn bayoolaji. noocyada tirayn

The sayniska rasmiga ah, waxaa jira wax sida kala duwan sida. Waxaa go'aamisa sida inta kale ee dadka waaweyn u shaqeeyo iyo waxa calaamadaha u bartaan doonaa in koorsada ee ay horumarka. Tirayn guud ahaan - waa awood u leh inay helaan oraganizma guryaha cusub.

Kala saaro tirayn hidaha iyo firka ahayn. Nongenetic ma saamayn dhismeedka hiddo. Isbedelada dhacaan oo keliya gudahood falcelinta caadiga ah. Taasi waa, phenotype ku kala duwan yihiin sida ugu badan waxay u saamaxdaa genotype ah. tirayn Non-hidda waa habeynta iyo koritaanka. ee la soo dhaafay A kala duwan waxaa kaloo loo yaqaan tirayn epigenetic.

tirayn ontogenetic

wejiyada jirka la xirrira Individual. Intii ay socotey kasta kara waxyaabo kala duwan deegaanka uu deegaanka saameeyeen. Ka dib oo dhan, wax kasta oo nool si ay u xuubsiiban in go'doomin ma karo. Oo sabab u ah saamaynta arrimo kala duwan u shaqeeyo keensataa sifooyinka cusub.

tirayn Ontogenetic waxa uu ku yaalaa isgoyska of tirayn hidaha iyo firka ahayn. Kala duwan waxa ay sidoo kale waxaa loo yaqaan tirayn epigenetic. Maxaad sidaa? Noocan ah kala duwanaansho waa ka dadka kale ee in calaamadaha cusub u muuqanno oo sabab u ah barnaamijyada hidaha soo jireenka ah, iyo waqti isku mid ah oo kala duwan ay sabab u tahay sifooyinka exogenous. Anigoo aan lahayn barnaamijyada sida, nooca ayaa lahaydeen kuwa Khasaaray xayawaan oo badan oo ku nool in eynu.

Fikradda ah ontogeny

Waa maxay ontogeny? Aragtidani waxa ay - mid ka mid ah koorsada aasaasiga ah ee biology. Si aad si fiican u fahmaan waxa tirayn ontogenetic, waxaad u baahan tahay inaad ogaato oo ku saabsan geedi socodka of ontogenesis. Dhab ahaantii, culumadu go'doonsan view of tirayn ku saleysan habka this.

Ontogenesis - horumarinta Hab-ka rimidda dhalan. Waa sahlan tahay si loo raad raaco habka this by tusaale ahaan ka mid ah balanbaalis ah. Markii hore diir dhashay (berdihii. 1) aasaasay xaggeeda caruusada (berdihii. 2, 3), kaas oo sidoo kale waa nolosha wareeg. Oo pupa ee dadka waaweyn ayaa umado - balanbaalis ah. sidoo kale Ontogenez hanti iyo dhirta.

All in dhacaya saygoot (ugxanta la bacrimiyey) si ay u dhamaystiraan formation of xayawaan ama aadanaha, loo baran karaa oo la falanqeeyay.

Tusaalooyinka si dabiici ah ka dhaca

Sababaha tirayn horumarineed, ku saleysan kor ku xusan - waa xaaladaha deegaanka iyo sifooyinka of genotype ah. Genotype - formula ah ee maamula isbedel dhan.

Sida loo xeeriyo tirayn ee genotype ah? shaqada shakhsiyaadka Genotype reguliret ah hiddo-gaar ah "shid" muddo qaar ka mid ah horumarinta. u shaqeeyo gaar dhaxlay waa laftiisa Aayad, iyo nooca reaction in saamaynta degaanada qaarkood. Kanu waa sharciga ku dabiiciga ah, kaas oo ku kaydsadaa fure u tahay inaad fahamto habka this sida kala duwan horumarineed. Tusaalooyinka kala duwanaansho noocan oo kale ah ka heli doonto dal oo kala duwan iyo qaaradood. tirayn noocan oo kale ah waa dabeecadda xayawaanka iyo cayayaanka, iyo boqortooyadii khudradda.

Track beddelayo midabka iyo qaabka dubka Andean rah nool Ecuador. Its isbadal inta lagu jiro ontogenesis - ka "formula" classic tirayn ontogenetic ee dabiiciga ah.

Rah Little ma laha nabro weheliyaan jidhka iyo dadka waaweyn, sida aan ku aragno, on dhinacyada ku dhista-up. maqaarka rah beddelayo midabka si coppery brown, iyo midabka ah ee iris of cas oo dhalaalaya noqdo orange coppery.

qiimaha tirayn

qiimaha Ontogenetic tirayn for duur - gaar ahaan qabsashada ee shaqsi kasta. onaa The wanaagsan, ayaa in ka badan zhiznesposbnosti noocyada ee xaaladaha deegaanka. macnaha kale ee tirayn - noocyo kala duwan oo phenotypes. shaqsi kasta wuxuu leeyahay, in tirayn ee sifooyinka shaqsi ay mahad.

By hagaajinta qabsashada waxaa isa soo taraysa nooc oo dhan. Inkastoo, dabcan, isbedel waa kuwan aad u gaabis ah.
