Phylogeny hais txog evolutionary keeb kwm ntawm hom. Phylogenetics yog kev kawm ntawm cov phylogenies - uas yog, txoj kev kawm ntawm evolutionary kev sib raug zoo ntawm hom. Hauv molecular phylogenetic tsom xam , qhov sib lawv liag ntawm cov noob los yog cov protein tuaj yeem siv los ntsuas qhov kev sib raug zoo ntawm cov tsiaj.

Yog li ntawd, koj ua li cas rau kev soj ntsuam phylogenetic?

Tsev a tsob ntoo phylogenetic yuav tsum muaj plaub kauj ruam sib txawv: (Kaum 1) txheeb xyuas thiab tau txais cov txheej txheem ntawm homologous DNA lossis protein ntau, (Kaum 2) ua raws cov kab ke, (Kaum 3) kwv yees ib tsob ntoo los ntawm cov kev sib txuas ua ke, thiab (Qib 4) nthuav tawm qhov ntawd tsob ntoo nyob rau hauv xws li kom meej meej qhia cov ntaub ntawv muaj feem xyuam rau lwm tus

Dhau li saum toj no, txhais li cas los ntawm kev sib raug zoo phylogenetic? “ Phylogogenetic kev sib raug zoo ” yog hais txog lub sijhawm txheeb ze yav dhau los uas hom sib koom ua poj koob yawm txwv.

Yog li ntawd, phylogenetic tsom xam bioinformatics yog dab tsi?

2 Qhia qee qhov kev siv ntau tshaj plaws rau phylogenetic tsom xam . ❚ Phylogeny - yog qhov evolution ntawm ib pawg neeg muaj feem cuam tshuam nrog cov kab mob. ❚ Lossis: kev kawm txog kev sib raug zoo ntawm kev sau ntawm "cov khoom" (genes, proteins, organs..) uas yog muab los ntawm ib tug poj koob yawm txwv.

Phylogram yog dab tsi?

A phylogram yog ib daim duab ceg ntoo (ntoo) uas yog qhov kwv yees ntawm phylogeny. Cov ceg ntev yog proportional rau tus nqi ntawm inferred evolutionary hloov. Yog li ntawd, cladograms qhia txog poj koob yawm txwv, tab sis tsis qhia tus nqi ntawm evolutionary "lub sij hawm" cais taxa.
