Qhov sib txawv tseem ceeb ntawm parthenogenesis thiab hermaphroditism yog qhov parthenogenesis yog ib lub tswv yim ua me nyuam uas qhia tau hais tias kev loj hlob ntawm lub embryo los ntawm lub zes qe menyuam tsis muaj menyuam thaum hermaphroditism yog lub tswv yim ntawm kev yug me nyuam ntawm cov kab mob uas muaj ob leeg txiv neej thiab poj niam cev xeeb tub.
Txhua lub tswv yim kev yug me nyuam tuaj yeem faib ua ob hom loj: kev sib deev thiab kev sib deev. Txoj kev yug me nyuam feem ntau yog kev sib deev hauv cov txiv neej thiab poj niam gametes sib sau ua ke kom tsim tau ib lub diploid zygote. Li no, qhov no yog txheej txheem hu ua fertilization. Tom qab fertilization thiab tsim ntawm lub zygote, zygote tsim mus rau hauv ib tug tshiab multicellular kab mob los ntawm mitotic division. Feem ntau cov kab mob suav nrog tib neeg tuaj yeem tsim cov xeeb ntxwv los ntawm kev sib deev. Ntawm qhov tod tes, asexual reproduction tsis xav tau ob niam txiv thiab gametes. Asexual reproduction tsim cov noob caj noob ces zoo tib yam ntawm mitosis. Ntxiv mus, meiosis tsis tshwm sim thaum lub sij hawm yug me nyuam asexual. Parthenogenesis thiab hermaphroditism yog ob hom kev sib txawv ntawm cov tswv yim kev loj hlob. Cov no zoo li tsis tiav cov ntaub ntawv ntawm kev sib deev kev sib deev vim lawv tsis muaj cov yam ntxwv ntawm cov txheej txheem kev sib deev tiag tiag. Txawm li cas los xij, ob qho tib si cov ntaub ntawv me nyuam yaus no yog qhov hloov tau zoo rau qee yam kab mob.
Parthenogenesis yog dab tsi?
Parthenogenesis yog ib hom kev sib txawv ntawm kev yug me nyuam asexual feem ntau pom ntawm ntau arthropods. Hauv cov txheej txheem no, cov poj niam muaj peev xwm tsim cov xeeb ntxwv los ntawm lawv cov qe tsis muaj menyuam. Yog li, fertilization tsis tshwm sim thaum lub sij hawm parthenogenesis. Tsis tas li ntawd, txiv neej gametes tsis koom nrog parthenogenesis.
Daim duab 01: Parthenogenesis
Qee cov kab mob yog tag nrho parthenogenic whereas qee cov kab mob muaj peev xwm tsim cov xeeb ntxwv los ntawm parthenogenesis thiab los ntawm kev sib deev. Piv txwv li, poj huab tais zib ntab muv tuaj yeem khaws cov phev thiab muaj kev tswj hwm kev tso cov phev, uas fertilize nws cov qe. Yog tias cov phev raug tso tawm, cov qe fertilized ib txwm tsim mus rau cov poj niam ua haujlwm bees thiab lwm tus poj huab tais. Ntawm qhov tod tes, yog tias tsis muaj cov phev tso tawm, cov qe tsis muaj menyuam loj hlob mus rau txiv neej bees hu ua drones. Hauv vertebrates, parthenogenesis tshwm sim ntawm qee hom lizards.
Hermaphroditism yog dab tsi?
Hermaphroditism yog lwm daim ntawv kev tsim tawm uas tuaj yeem pom ntawm cov kab mob uas muaj ob qho tib si qog thiab zes qe menyuam. Cov kab mob uas muaj peev xwm no hu ua hermaphrodites. Txij li thaum hermaphrodites muaj ob qho tib si txiv neej thiab poj niam cev xeeb tub, lawv tuaj yeem tsim cov phev thiab qe hauv lawv lub cev. Cov tswv yim no muaj txiaj ntsig zoo rau qee cov kab mob. Piv txwv li, tapeworms yog hermaphrodites siv txoj kev no vim nws tsis zoo li yuav ntsib lwm tus kab mob hauv tib tus tswv tsev. Txawm li cas los xij, ntau zaus, kev tsim tawm yuav tsum muaj ob lub hermaphrodites; piv txwv, earthworms.
Daim duab 02: Hermaphroditism
Ntxiv rau, qee hom ntses uas nyob hauv hiav txwv tob kuj yog hermaphrodites. Qee hom ntses, coral reef ntses, piv txwv li, muaj peev xwm hloov tau lawv txoj kev sib deev raws li lawv txoj kev tswj hwm. Peb hu cov txheej txheem no ua ntu zus hermaphroditism.
Dab tsi yog qhov zoo sib xws ntawm Parthenogenesis thiab Hermaphroditism?
- Parthenogenesis thiab hermaphroditism yog ob hom kev ua me nyuam.
- Gamete ntau lawm yog tsim nyog rau txhua txoj kev.
Qhov txawv ntawm Parthenogenesis thiab Hermaphroditism yog dab tsi?
Parthenogenesis thiab hermaphroditism yog ob hom kev yug me nyuam uas peb tuaj yeem pom hauv cov kab mob sib txawv. Parthenogenesis hais txog cov txheej txheem ntawm kev tsim cov xeeb ntxwv los ntawm lub qe unfertilized yam tsis muaj kev koom tes ntawm ib tug txiv neej gamete. Txawm li cas los xij, hermaphroditism yog ib lub tswv yim ua me nyuam ntawm cov kab mob uas muaj ob qho tib si txiv neej thiab poj niam cev xeeb tub. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm parthenogenesis thiab hermaphroditism.
Hauv parthenogenesis, ovum tsis fuse nrog txiv neej gamete. Tab sis, nyob rau hauv hermaphroditism, ob leeg txiv neej thiab poj niam gametes fertilize los tsim cov xeeb ntxwv. Yog li ntawd, tsis muaj fertilization tshwm sim thaum lub sij hawm parthenogenesis thaum nws tus kheej fertilization tshwm sim thaum lub sij hawm hermaphroditism. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm parthenogenesis thiab hermaphroditism. Qhov sib txawv ntawm qhov sib txawv no yog lwm qhov sib txawv ntawm parthenogenesis thiab hermaphroditism. Qhov ntawd yog; parthenogenesis ib txwm tshwm sim nyob rau hauv ib tug neeg uas tsuas tsim tau poj niam gametes (qe), whereas hermaphroditism tshwm sim nyob rau hauv ib tug neeg uas muaj peev xwm tsim tau ob leeg poj niam thiab txiv neej gametes.
Cov hauv qab no qhia txog qhov sib txawv ntawm parthenogenesis thiab hermaphroditism hauv daim ntawv teev npe.
Summary – Parthenogenesis vs Hermaphroditism
Parthenogenesis yog ib hom kev yug me nyuam uas lub zes qe menyuam loj hlob mus rau hauv lub embryo yam tsis muaj fertilization nrog phev. Txawm li cas los xij, hermaphroditism yog hais txog kev yug me nyuam uas pom los ntawm cov kab mob bisexual. Lawv muaj ob qho tib si txiv neej thiab poj niam cev xeeb tub, yog li tsim ob hom gametes. Earthworms, corals, tapeworms, qee cov ntses qhia hermaphroditism thaum lizards, muv thiab qee cov nroj tsuag qhia parthenogenesis. Yog li, qhov no qhia txog qhov sib txawv ntawm parthenogenesis thiab hermaphroditism.
