Qhov sib txawv tseem ceeb ntawm cytoplasmic qub txeeg qub teg thiab cov qub txeeg qub teg nuclear yog qhov qub txeeg qub teg cytoplasmic tshwm sim los ntawm cov noob muaj nyob rau hauv cytoplasmic organelles thaum nuclear qub txeeg qub teg tshwm sim los ntawm cov noob muaj nyob rau ntawm chromosomes.
Fertilization yog kev sib xyaw ntawm txiv neej thiab poj niam gametes ua ke. Yog li ntawd, thaum lub sij hawm fertilization, haploid phev thiab haploid qe cell sib sau ua ke thiab tsim ib tug diploid zygote. Sperm cell hloov nws cov nucleus mus rau lub qe cell rau fusion. Lub resultant zygote muaj lub cytoplasm ntawm lub qe cell. Hauv cov lus yooj yooj yim, cytoplasm ntawm lub qe qe ua lub cytoplasm ntawm zygote. Ntxiv mus, cov xeeb ntxwv tau txais cov noob los ntawm ob qho tib si nuclei thiab cov noob ntawm leej niam cytoplasmic organelles. Cov noob ntawm nuclei thiab cov noob ntawm cytoplasmic organelles tau txais los ntawm cov xeeb ntxwv. Yog li ntawd, muaj ob hom kev qub txeeg qub teg tshwm sim thaum muaj kev sib deev fertilization. Lawv yog cytoplasmic qub txeeg qub teg thiab nuclear qub txeeg qub teg.
Cytoplasmic Inheritance yog dab tsi?
Cytoplasmic qub txeeg qub teg yog ib hom qub txeeg qub teg uas muaj DNA ntawm cytoplasmic organelles. Hauv qhov qub txeeg qub teg no, cov xeeb ntxwv tau txais cov noob los ntawm cytoplasmic organelles (plasma genes lossis extranuclear genes). Mitochondria thiab chloroplasts muaj cov genomes tsim los ntawm DNA. Cov organelle DNA no taug kev los ntawm niam qe cell mus rau zygote. Txawm li cas los xij, piv rau cov qub txeeg qub teg nuclear, tsawg tsawg ntawm cov noob tau txais los ntawm cytoplasmic qub txeeg qub teg. Ntxiv mus, nws tsis ua raws li Mendelian qub txeeg qub teg, tsis zoo li nuclear qub txeeg qub teg.
Daim duab 01: Cytoplasmic Inheritance ntawm Mitochondrial DNA
Tsis tas li ntawd, ntxiv-chromosomal qub txeeg qub teg, ntxiv-nuclear qub txeeg qub teg, somal qub txeeg qub teg thiab niam txiv qub txeeg qub teg yog ob peb lub ntsiab lus rau cytoplasmic qub txeeg qub teg.
Nuclear Inheritance yog dab tsi?
Nuclear qub txeeg qub teg tshwm sim vim cov noob muaj nyob rau ntawm chromosomes. Yog li ntawd, niam nucleus thiab leej txiv nucleus sib npaug sib npaug rau cov qub txeeg qub teg nuclear. Tsis tas li ntawd, cov xeeb ntxwv tau txais ntau lab ntawm cov noob los ntawm niam txiv los ntawm kev qub txeeg qub teg nuclear.
Daim duab 02: Fertilization
Tsis tas li ntawd, qhov qub txeeg qub teg no ua raws Mendelian qub txeeg qub teg. Nuclear noob tuaj yeem cuam tshuam cov noob koom nrog hauv cytoplasmic qub txeeg qub teg.
Dab tsi zoo sib xws ntawm Cytoplasmic Inheritance thiab Nuclear Inheritance?
- Cytoplasmic qub txeeg qub teg thiab nuclear qub txeeg qub teg yog ob hom qub txeeg qub teg uas piav txog kev hloov cov noob ntawm niam txiv mus rau cov xeeb ntxwv.
- Nyob rau hauv ob txoj kev qub txeeg qub teg, cov xeeb ntxwv xeeb tub.
- Ntxiv mus, lawv yog cov txheej txheem tseem ceeb heev tshwm sim hauv cov kab mob nyob.
Qhov txawv ntawm Cytoplasmic Inheritance thiab Nuclear Inheritance yog dab tsi?
Cytoplasmic qub txeeg qub teg yog kev hloov pauv ntawm cov noob tam sim no hauv cov kab mob ntawm cov cytoplasm thaum cov khoom qub txeeg qub teg yog hloov cov noob muaj nyob rau ntawm chromosome. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cytoplasmic inheritance thiab nuclear qub txeeg qub teg. Lwm qhov sib txawv ntawm cytoplasmic qub txeeg qub teg thiab cov qub txeeg qub teg nuclear yog qhov qub txeeg qub teg cytoplasmic feem ntau yog leej niam, hos nuclear qub txeeg qub teg yog los ntawm leej niam thiab leej txiv.
Summary – Cytoplasmic Inheritance vs Nuclear Inheritance
Cytoplasmic qub txeeg qub teg yog kev sib kis ntawm cov noob los ntawm cov cytoplasmic organelles uas tshwm sim sab nraum lub nucleus thaum nuclear qub txeeg qub teg yog kis ntawm cov noob los ntawm chromosomes tam sim no hauv lub nucleus. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Cytoplasmic Inheritance thiab Nuclear Inheritance.
