Qhov sib txawv tseem ceeb ntawm monospermy thiab polyspermy yog tias monospermy yog hais txog cov txheej txheem ntawm fertilizing lub qe qe nrog ib cov phev. Meanwhile, lub polyspermy hais txog cov txheej txheem ntawm fertilizing lub qe cell nrog ntau tshaj ib tug phev.
Fertilization yog kev sib koom ua ke ntawm lub qe qe nrog cov phev cell. Nws tshwm sim thaum muaj kev sib deev. Ib txwm fertilization muaj kev cuam tshuam ntawm ib phev thiab ib lub qe (monospermy). Yog li ntawd, lub qe tso cai rau ib tug phev kom fertilize nws. Txawm li cas los xij, muaj qee zaus uas lub qe qe ua polyspermic los ntawm kev tso cov phev ntxiv nkag mus rau cytoplasm ntawm lub qe qe.
Monospermy yog dab tsi?
Monospermy yog cov txheej txheem ib txwm ntawm fertilization ntawm qe qe nrog cov phev. Yog li, nws tsuas muaj ib lub qe qe thiab ib cov phev xwb. Thaum cov phev nkag mus rau hauv cytoplasm ntawm lub qe cell, nws tiv thaiv kev nkag mus ntawm cov phev ntxiv los ntawm kev tsim cov blocks ntawm zona pellucida thiab qe ntshav plasma membrane. Los ntawm kev ua nws, fertilization tswj tus lej chromosome tas li hauv txhua tiam.
Daim duab 01: Monospermy
Feem ntau, gametes muaj ib pawg chromosomes. Thaum lub qe thiab cov phev sib sau ua ke, nws tsim ib lub diploid zygote uas muaj tus lej ntawm cov chromosomes ntawm cov noob qoob loo.
YPolyspermy yog dab tsi?
Polyspermy yog fertilization ntawm lub qe nrog ntau tshaj ib tug phev. Qhov no tshwm sim thaum lub qe qe tso cai rau ntau tshaj ib cov phev nkag mus rau cytoplasm ntawm lub qe cell. Yog li, nws tsim ib lub cell uas muaj ntau tshaj ob pawg ntawm chromosomes. Hauv cov lus yooj yim, polyspermy tsim cov kab mob uas muaj peb lossis ntau pawg ntawm chromosomes; qe cell pab txhawb ib chromosome teeb thaum lwm cov chromosome teeb los ntawm ntau cov phev. Yog li, feem ntau ntawm cov sij hawm, polyspermy yog pathological. Nws tsim ib lub embryo uas txawv txav thiab tsis siv tau.
Daim duab 02: Polyspermy
Txawm li cas los xij, hauv qee cov se, ntau cov phev nkag mus rau lub qe uas tsis muaj qhov cuam tshuam rau zygote viability. Ntxiv mus, kwv yees li 7% ntawm fertilized tib neeg qe yog polyspermic.
Dab tsi yog qhov zoo sib xws ntawm Monospermy thiab Polyspermy?
- Monospermy thiab polyspermy yog ob hom fertilization.
- Nyob rau hauv ob hom, lub zes qe menyuam koom nrog cov phev.
Qhov txawv ntawm Monospermy thiab Polyspermy yog dab tsi?
Monospermy yog fertilization ntawm ib qho oocyte los ntawm ib tus spermatozoon. Nyob rau hauv sib piv, polyspermy yog fertilization ntawm ib tug oocyte los ntawm ntau tshaj ib tug spermatozoan. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm monospermy thiab polyspermy. Monospermy yog ib txwm fertilization tshwm sim nyob rau hauv cov kab mob thaum polyspermy yog ib qho txawv txav nyob rau hauv fertilization uas ua rau ib tug tsis siv tau embryo.
Tsis tas li ntawd, monospermy ua rau diploid zygote thaum polyspermy ua rau triploid lossis multiploid embryo. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm monospermy thiab polyspermy. Qhov tseem ceeb tshaj plaws, monospermy tsis yog pathological thaum polyspermy yog pathological vim muaj tus lej ntawm chromosomes txawv txav.
Summary – Monospermy vs Polyspermy
Monospermy thiab polyspermy yog ob hom fertilization. Monospermy yog ib txwm fertilization uas tshwm sim ntawm lub qe thiab cov phev. Polyspermy yog ib hom kev fertilization txawv txav uas lub qe cell tso cai nkag mus rau ntau tshaj ib tug phev mus rau nws cytoplasm. Monospermy tsim cov kab mob diploid, thaum polyspermy tsim cov kab mob triploid lossis multiploid. Feem ntau, polyspermy ua rau muaj kev cuam tshuam tsis zoo rau lub embryo, thiab ntau zaus, nws ua rau lub cev tsis muaj zog. Nyob rau hauv sib piv, monospermy tsim ib tug siv tau embryo, thiab nws tsis yog-pathological. Yog li, qhov no qhia txog qhov sib txawv ntawm monospermy thiab polyspermy.
