Qhov Tseem Ceeb Qhov txawv - Autopolyploidy vs Allopolyploidy
Polyploidy yog hais txog ib hom chromosomal aberration uas ua rau lub cev muaj peb lossis ntau pawg ntawm chromosomes, es tsis txhob muaj cov mob diploid. Feem ntau, polyploidy yog siv hauv kev cog qoob loo thiab nws tau pom cov txiaj ntsig zoo hauv kev tsim cov hybrid ntau yam. Yog li, polyploid ntau yam yog piav qhia hauv cov nroj tsuag biology. Polyploids feem ntau yog tsim los ntawm kev tsis sib haum xeeb ntawm tus muam chromatids thaum lub sij hawm mitosis. Muaj ob lub ntsiab ntawm polyploidy; Autopolyploidy thiab Allopolyploidy. Autopolyploidy yog ib yam mob uas ib tug kab mob yog tsim los ntawm peb los yog ntau tshaj ntawm chromosomes tau txais los ntawm tib hom uas zoo sib xws genomes. Alloploidy yog ib yam mob uas ib tug kab mob yog tsim los ntawm peb los yog ntau tshaj ntawm chromosomes tau txais los ntawm ntau hom nrog txawv genomes. Qhov sib txawv tseem ceeb ntawm Autopolyploidy thiab Allopolyploidy yog hom kab mob uas ua rau muaj qhov mob polyploidy. Hauv Autopolyploidy, pawg chromosomes tau txais yog tib hom genome, whereas nyob rau hauv Allopolyploidy, cov kab mob yog tsim los ntawm peb lossis ntau pawg ntawm chromosomes tau txais los ntawm cov kab mob ntawm ntau hom genome.
Autopolyploidy yog dab tsi?
Autopolyploidy yog qhov mob uas ib tus kabmob tau txais ntau pawg chromosomes los ntawm tib hom genome lossis tib hom. Autopolyploidy feem ntau ua rau muaj tus lej ntawm chromosomes. Vim qhov zoo sib xws ntawm cov chromosomes, lawv tau txais kev sib koom ua ke sib txawv thaum lub sijhawm meiosis.
Autopolyploids tuaj yeem muab faib ua ob pawg raws li qhov zoo sib xws ntawm cov genome siv hauv kev tsim cov hybrid polyploid ntau yam. Yog li ntawd, autopolyploids tau muab faib ua nruj autopolyploids thiab interracial autopolyploids. nruj autopolyploidy yog hais txog qhov tshwm sim uas ib tug hybrid yog tsim los ntawm ob npaug ntawm chromosomes ntawm tib lub cev. Interracial autopolyploidy yog qhov tshwm sim uas cov hybrid yog tsim los ntawm kev hla uas tshwm sim ntawm cov kab mob sib txawv uas muaj tib genotype.
Daim duab 01: alfalfa
Nyob rau hauv cov xwm txheej khoom tsim, autopolyploidy tuaj yeem raug ntxias los ntawm colchicine. Colchicine yog ib qho alkaloid uas tsim los ntawm cov nroj tsuag saffron meadow. Colchicine muaj peev xwm cuam tshuam txoj kev loj hlob ntawm nuclear spindle. Lub mitosis uas ua raws li kev kho mob ntawm colchicine yog hu ua C - mitosis thiab nws ua rau tsim bivalents. Ntau cov nroj tsuag cog yog autopolyploids. Piv txwv suav nrog tetraploid Qos yaj ywm thiab alfalfa.
Allopolyploidy yog dab tsi?
Allopolyploidy yog qhov tshwm sim uas muaj ntau yam hybrid tsim los ntawm kev tau txais peb lossis ntau pawg ntawm chromosomes los ntawm cov noob caj noob ces tsis muaj ntau yam. Yog li ntawd, lawv tsis muaj cov genomes zoo sib xws thiab lawv koom nrog ntau hom tsiaj. Allopolyploids tuaj yeem muaj qhov sib txawv lossis txawv ntawm chromosomes. Multivalents yog tsim los ntawm bivalents nyob rau hauv allopolyploidy.
Type of Allopolyploidy
Allopolyploids tuaj yeem muab faib ua ntau hom;
- Segmental allopolyploidy
- Complete allopolyploidy
- Muaj tseeb lossis Genomic polyploidy
- Auto-allopolyploidy
- Aneuploidy
Daim duab 02: Ib qho piv txwv ntawm Allopolyploid yog Paj Rwb
Piv txwv ntawm allopolyploids yog paj rwb - 13 khub thiab 53 chromosomes, nplej - 7 khub thiab 42 chromosomes.
Dab tsi yog qhov zoo sib xws ntawm Autopolyploidy thiab Allopolyploidy?
- Ob hom muaj nyob rau hauv cov mob polyploidy qhov twg cov chromosomes nce ntxiv piv rau cov suav ib txwm.
- Ob hom yog siv los tsim cov hybrid ntau yam.
- Ob hom no feem ntau pom hauv kev cog qoob loo.
Qhov txawv ntawm Autopolyploidy thiab Allopolyploidy yog dab tsi?
Autopolyploidy vs Allopolyploidy |
|
| Autopolyploidy yog tus mob uas ib yam kabmob muaj li ntawm peb lossis ntau pawg ntawm chromosomes tau txais los ntawm tib hom nrog cov genomes zoo sib xws. | Alloploidy yog ib yam mob uas ib tug kab mob yog tsim los ntawm peb los yog ntau tshaj ntawm chromosomes tau txais los ntawm ntau hom nrog txawv genomes. |
| Tus naj npawb ntawm Chromosomes | |
| Txawm cov chromosomes tuaj yeem pom hauv autopolyploidy mob. | Allopolyploidy mob tuaj yeem muaj tus lej sib npaug lossis tus lej khib ntawm chromosomes. |
| Kev tsim ntawm Sister Chromatids | |
| Bivalent yog tsim nyob rau hauv autopolyploidy. | Multivalent yog tsim nyob rau hauv allopolyploidy. |
Summary – Autopolyploidy vs Allopolyploidy
Polyploids yog tsim los ntawm kev tsis sib haum xeeb tshwm sim nyob rau hauv theem mitosis uas yuav ua rau bivalents lossis multivalents. Autopolyploidy yog qhov tshwm sim uas ib tus kab mob tau txais peb lossis ntau pawg ntawm chromosomes los ntawm cov kab mob uas muaj cov genomes zoo sib xws, whereas allopolyploidy yog qhov tshwm sim uas cov kab mob hybrid tau txais peb lossis ntau pawg ntawm chromosomes los ntawm cov kab mob uas tsis muaj cov genomes zoo sib xws. Kev tsim ob hom polyploids tau pom tias muaj txiaj ntsig zoo hauv kev cog qoob loo thiab cog qoob loo. Qhov no yog qhov txawv ntawm autopolyploidy thiab allopolyploidy.
