Fertilized vs Unfertilized Eggs

Qhov sib txawv ntawm fertilized thiab unfertilized qe tshwm sim raws li qhov tshwm sim ntawm cov txheej txheem lom neeg lub qe undergo. Tus poj niam gamete feem ntau hu ua qe. Peb faib cov poj niam gametes los yog qe rau hauv lub qe fertilized thiab unfertilized raws li tus txheej txheem hu ua fusion los yog fertilization. Kab lus hauv qab no piav qhia txog cov txheej txheem no koom nrog thiab qhov sib txawv ntawm cov qe fertilized thiab unfertilized qe uas yog tshwm sim los ntawm cov txheej txheem no.

Qe Fertilized yog dab tsi?

Fertilized qe tseem hu ua zygote hauv cov txheej txheem ntawm kev loj hlob. Fusion ntawm haploid poj niam gamete (ovum) nrog ib tug txiv neej haploid gamete (phev) los ua diploid zygote yog hu ua fertilization. Li no, fertilized qe thaum kawg tsim ib tug kab mob diploid los ntawm mitotic division. Muaj ob hom fertilization, uas yog; (a) Internal fertilization qhov twg fertilization tshwm sim nyob rau hauv tus poj niam lub cev thiab (b) sab nraud fertilization, qhov twg fertilization tshwm sim sab nraum tus poj niam lub cev. Thaum lub zygote tsim, nws nkag mus rau hauv cell division sai heev los tsim ib tug tshiab kab mob. Lub zygote muaj peev xwm tsim tau txhua yam ntawm cov hlwb hauv lub cev. Vim yog kev sib xyaw ntawm txiv neej thiab poj niam gametes los tsim cov kab mob diploid, peb hu cov txheej txheem no 'kev sib deev deev.'

Eg Unfertilized yog dab tsi?

Ib lub qe uas tsis muaj menyuam yog lub zes qe menyuam, uas tsis tau fused nrog txiv neej gamete (sperm). Txij li thaum lub qe unfertilized tsis fertilized, nws yog ib txwm haploid thiab tsuas yog ib pawg ntawm chromosomes pom nyob rau hauv nws. Vim tsis muaj fertilization, ib lub qe unfertilized yeej tsis tsim ib tug me nyuam diploid los ntawm kev sib deev kev sib deev. Txawm li cas los xij, qee hom nroj tsuag thiab tsiaj txhu tau tsim lwm txoj hauv kev ua me nyuam los tsim lawv cov xeeb ntxwv los ntawm cov qe uas tsis muaj menyuam. Cov txheej txheem no hu ua asexual reproductive method. Ib qho piv txwv zoo rau qhov no yog parthenogenesis, uas muaj nyob rau hauv ntau hom arthropods. Tsis tas li ntawd, qee cov lizards, ntses, thiab salamanders kuj qhia parthenogenesis. Qee hom tsuas yog parthenogenic nkaus xwb, tab sis qee qhov tuaj yeem hloov pauv ntawm kev sib deev thiab parthenogenesis. Hauv honeybees, piv txwv li, poj huab tais tuaj yeem khaws thiab tswj kev tso cov phev. Thaum nws tso cov phev, cov qe tsim kev sib deev rau hauv cov poj niam ua haujlwm muv diploid. Yog tias tsis muaj cov phev tso tawm, cov qe tsis muaj fertilized tsim parthenogenetically rau hauv cov txiv neej haploid bees.

Qhov txawv ntawm Fertilized thiab Unfertilized qe yog dab tsi?

Definition of Fertilized and Unfertilized Eggs:

• Fertilized qe yog tsim los ntawm fusion ntawm haploid poj niam gamete nrog txiv neej haploid gamete.

• Lub qe uas tsis muaj menyuam yog lub qe uas tsis tau fused nrog txiv neej gamete.

Fertilization:

• Fertilization tshwm sim los tsim qe fertilized.

• qe Unfertilized yog tsim thaum tsis muaj fertilization.

Kev txhim kho:

• Fertilized qe yeej ib txwm tsim los ua ib qho kab mob diploid.

• Hauv qee yam kab mob, qe tsis muaj menyuam tuaj yeem tsim cov kab mob haploid.

Txoj Kev Sib Tw:

• Fertilized qe yog tsim thaum lub sij hawm kev sib deev.

• Asexual reproduction ua rau cov xeeb leej xeeb ntxwv los ntawm unfertilized qe.
