Qhov txawv ntawm Singleton qhov chaw thiab Parsimony yog dab tsi - Cov chaw qhia paub ? Singleton tsuas yog ua ib qho piv txwv tsim thiab muaj tsawg kawg 2 hom nucleotides thiab tshwm sim ntau zaus. Thaum parsimony - cov chaw qhia paub kuj muaj 2 nucleotides tab sis tsuas yog ob ntawm lawv tshwm sim nrog a tsawg zaus ntawm ob.

Kuj nug, qhov txawv ntawm Singleton qhov chaw thiab cov chaw qhia parsimony yog vim li cas PI qhov chaw muaj txiaj ntsig zoo rau kev txiav txim siab Phylogentic kev sib raug zoo thaum S qhov chaw tsis yog?

PI sites yog pab tau rau kev txiav txim phylogenetic kev sib raug zoo vim lawv muaj ob tug txawv nucleotides uas tuaj yeem tshwm sim ntau dua ob zaug thiab qhia tias tsob ntoo twg ntau dua parsimonious.

Kuj Paub, qhov chaw sib txawv yog dab tsi? A qhov chaw sib txawv muaj tsawg kawg yog ob hom nucleotides lossis amino acids. Ib txhia cov chaw sib txawv tuaj yeem yog singleton lossis parsimony-cov ntaub ntawv. A qhov chaw uas tsis yog sib txawv yog hu ua qhov tsis tu ncua qhov chaw.

Ib yam li ntawd, cov chaw qhia ntawv parsimony yog dab tsi?

Parsimony - qhov chaw qhia paub . A qhov chaw yog parsimony - qhia paub yog tias nws muaj tsawg kawg yog ob hom nucleotides (los yog amino acids), thiab tsawg kawg yog ob ntawm lawv tshwm sim nrog tsawg zaus ntawm ob.

Ua li cas koj thiaj paub tias tsob ntoo twg yog tus parsimonious tshaj plaws?

Rau nrhiav tus tsob ntoo uas yog feem ntau parsimonious , biologists siv brute computational quab yuam. Lub tswv yim yog tsim txhua yam ua tau ntoo rau cov se xaiv, qhia cov cim rau hauv ntoo , thiab xaiv cov tsob ntoo nrog tsawg tus lej ntawm evolutionary hloov.
