Qhov sib txawv tseem ceeb ntawm somatogenic thiab blastogenic variation yog qhov kev hloov pauv ntawm somatogenic cuam tshuam rau somatic lub cev hlwb ntawm cov kab mob thiab tsis muaj txiaj ntsig, thaum blastogeic variation cuam tshuam rau cov kab mob ntawm cov kab mob thiab tau txais txiaj ntsig.
Variation yog morphological, physiological, cytological, lossis behaviouristic txawv ntawm cov tib neeg ntawm tib hom thiab cov xeeb ntxwv ntawm tib niam txiv. Lawv tuaj yeem pom hauv txhua tus cim. Yog li ntawd, tsis muaj ob tus neeg zoo sib xws vim cov kev hloov pauv no. Variations txawm tshwm sim nyob rau hauv clones thiab monozygotic ntxaib. Kev hloov pauv yog cais raws li qhov sib txawv xws li cuam tshuam zoo, cuam tshuam, qhov chaw, qib, hlwb cuam tshuam (somatogenic thiab blastogenic), thiab lwm yam. Somatogenic thiab blastogenic variations yog ob hom kev hloov pauv raws li cov hlwb cuam tshuam hauv lub cev.
Somatogenic Variation yog dab tsi?
Qhov kev hloov pauv ntawm somatogenic lossis somatic cuam tshuam cuam tshuam rau lub cev somatic hlwb ntawm cov kab mob. Txij li thaum somatic hlwb raug cuam tshuam, nws tsis yog qub txeeg qub teg. Kev hloov pauv ntawm somatogenic yog vim muaj kev cuam tshuam sab nraud ntawm lub cev ntawm cov kab mob. Hom kev hloov pauv no tsis dhau mus rau tiam tom ntej. Thaum lub cev tuag, qhov kev hloov pauv no xaus. Somatic variation tseem hu ua cov cim tau los lossis hloov kho raws li cov tib neeg tau txais cov cim no thaum lawv lub neej.
Daim duab 01: Somatogenic Variation
Feem ntau, kev hloov pauv ntawm somatogenic tshwm sim vim yog peb yam: ib puag ncig, kev siv thiab kev siv lub cev, thiab kev mob siab rau. Qee qhov xwm txheej ib puag ncig uas ua rau muaj kev hloov pauv ntawm somatogenic yog qhov nruab nrab, lub teeb, kub, khoom noj khoom haus, cua, dej thiab khoom siv. Kev hloov pauv hauv phenotype hauv kev teb rau qhov sib txawv ib puag ncig yog hu ua phenotype plasticity. Ntxiv mus, ib qho phenotype tshwj xeeb uas tau tsim los teb rau ib qho xwm txheej ecological hu ua ecophenotype. Somatogenic variation nyob rau hauv cov tsiaj siab dua tshwm sim los ntawm kev siv thiab kev siv ntawm lub cev. Piv txwv li, cov khoom nruab nrog cev uas tau muab tso rau kev siv txuas ntxiv txhim kho ntau dua thaum lub cev uas siv tsawg dua me ntsis. Tsis tas li ntawd, ib qho kev hloov pauv ntawm somatogenic uas yog vim kev siv lub siab xav pom tsuas yog hauv cov tsiaj ntse. Qee qhov piv txwv ntawm kev mob siab rau yog kev cob qhia qee tus tsiaj, tau txais kev kawm, kev hloov pauv hauv cov tsiaj, lub cev yuag, caj dab ntev, thiab lwm yam.
Blastogenic Variation yog dab tsi?
Qhov blastogenic lossis kab mob sib txawv cuam tshuam rau cov kab mob ntawm cov kab mob. Yog li ntawd, hom variation no yog inheritable. Blastogenic variation tuaj yeem tshwm sim hauv cov poj koob yawm txwv lossis tuaj yeem tsim dheev. Blastogenic variation yog ob hom: nruam lossis tsis txuas ntxiv.
Daim duab 02: Blastogenic variation
Nruam blastogenic variation yog qhov muaj nuj nqis. Nruam blastogenic variation twb muaj nyob rau hauv lub cev. Nws tshwm sim vim yog vim li cas xws li lub caij nyoog sib cais ntawm chromosomes ntawm gamete tsim, hla ntawm chromosomes ntawm meiosis thiab muaj feem ua ke ntawm chromosomes thaum lub sij hawm fertilization, thiab lwm yam. Discontinuous blastogenic variation yog txhais raws li tam sim ntawd, unpredictable, inheritable departures los ntawm ib txwm tsis muaj ib nrab theem.. Tsis tas li ntawd, kev hloov pauv tsis tu ncua ntawm blastogenic tuaj yeem tshwm sim vim muaj ntau yam xws li chromosome aberrations xws li kev tshem tawm, luam tawm, hloov pauv, hloov pauv, hloov pauv hauv cov lej chromosome xws li aneuploidy, polyploidy thiab hloov pauv hauv cov qauv noob thiab kev qhia xws li ntxiv, tshem tawm, lossis hloov nucleotides.
Dab tsi yog qhov zoo sib xws ntawm Somatogenic thiab Blastogenic Variation?
- Somatogenic thiab blastogenic variations yog ob hom kev hloov pauv raws li cov hlwb cuam tshuam hauv lub cev.
- Ob qhov kev hloov pauv coj tawm phenotypic hloov pauv hauv lub cev.
- Cov kev hloov pauv no tuaj yeem ua rau muaj txiaj ntsig ntxiv rau kev muaj sia nyob ntawm lub cev.
- Lawv ob leeg cuam tshuam rau lub cev ntawm lub cev.
Qhov txawv ntawm Somatogenic thiab Blastogenic Variation yog dab tsi?
Qhov kev hloov pauv ntawm somatogenic cuam tshuam rau lub cev somatic lub cev ntawm cov kab mob thiab tsis tuaj yeem tau txais txiaj ntsig, thaum blastogenic variation cuam tshuam rau cov kab mob ntawm cov kab mob thiab tau txais txiaj ntsig. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm somatogenic thiab blastogenic variation. Tsis tas li ntawd, somatogenic variation tshwm sim thaum lub sij hawm lub neej ntawm ib tug neeg, thaum blastogenic variation tshwm sim thaum lub gametogenesis nyob rau hauv cov niam txiv.
Cov hauv qab no infographic teev qhov sib txawv ntawm somatogenic thiab blastogenic variation nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Somatogenic vs Blastogenic Variation
Variations tuaj yeem pom hauv txhua tus cim. Yog li ntawd, tsis muaj ob tus neeg zoo sib xws vim cov kev hloov pauv no. Somatogenic thiab blastogenic variations yog ob hom kev hloov pauv. Kev hloov pauv ntawm somatogenic cuam tshuam rau lub cev somatic lub cev ntawm cov kab mob, thiab nws tsis tau txais txiaj ntsig. Ntawm qhov tod tes, blastogenic variation cuam tshuam cov kab mob ntawm cov kab mob, thiab nws yog qhov qub. Yog li, qhov no yog qhov txawv ntawm somatogenic thiab blastogenic variation.
