(Original post by nelemauddin) A homologous khub yog a khub ntawm chromosomes uas muaj leej niam thiab leej txiv chromatid koom ua ke ntawm centromere. Cov noob muaj tib lub noob - txawm tias tej zaum yuav muaj qhov sib txawv ntawm cov noob no, Txoj Haujlwm (loci) thiab qhov loj me.
Tsis tas li lo lus nug yog, leej twg yog homologous chromosome khub?
homologous khub yog cov chromosomes uas muaj cov noob rau tib yam tab sis muaj cov alleles sib txawv, cov no chromosomes feem ntau yog ua ke ua ke thaum lub sij hawm mitosis. sciencesolve | Tub kawm. Ob qhov zoo sib xws chromosomes hu ua homologous chromosomes.
Ib yam li ntawd, koj yuav txheeb xyuas homologous chromosomes li cas? Homologous chromosomes tuaj yeem yog txheeb xyuas thaum pib ntawm meiosis. Ib tug tswv cuab ntawm txhua khub los ntawm niam txiv (niam) thiab lwm tus los ntawm txiv neej niam txiv. Niam thiab txiv chromosomes hauv a homologous khub muaj tib lub noob ntawm tib loci, tab sis tej zaum txawv alleles.
Tsis tas li ntawd, puas yog homologous chromosomes caj ces zoo ib yam?
Ib chromosome ntawm txhua tus homologous khub los ntawm niam (hu ua niam chromosome ) thiab ib tug los ntawm leej txiv (paternal chromsosome). Homologous chromosomes zoo ib yam tab sis tsis yog zoo ib yam . Txhua tus nqa tib cov noob hauv tib qho kev txiav txim, tab sis cov alleles rau txhua qhov zoo yuav tsis zoo ib yam.
Yuav ua li cas homologous chromosomes tsim?
Homologous chromosomes replicate los ntawm tsim zoo tib yam luam ntawm chromosomes hu ua muam chromatids. Interphase: Homologous chromosomes replicate rau tus muam chromatids. Prophase: Muam chromatids tsiv mus rau qhov chaw ntawm lub cell. Metaphase: Muam chromatids ua ke nrog cov phaj metaphase ntawm lub xov tooj ntawm tes.
Pom zoo:
Dab tsi yog qhov txawv ntawm chromosomes chromatids thiab homologous chromosomes?
Nws yog ib qho tseem ceeb kom nco ntsoov qhov sib txawv ntawm tus muam chromatids thiab homologous chromosomes. Sister chromatids yog siv nyob rau hauv cell division, zoo li nyob rau hauv lub cell hloov, whereas homologous chromosomes yog siv nyob rau hauv reproductive faib, zoo li ua ib tug neeg tshiab. Sister chromatids yog genetic tib yam
Yuav ua li cas yog lub appendix homologous rau lwm yam tsiaj homologous qauv qhia li cas?
Tib neeg appendix (ib lub hnab me me nyob ze ntawm qhov sib tshuam ntawm txoj hnyuv me thiab loj) yog homologous rau cov qauv hu ua 'caecum', lub tsev loj, qhov muag tsis pom kev hauv cov nplooj thiab cov nyom tau zom hauv ntau lwm yam tsiaj. Cov ntawv ntxiv feem ntau hu ua 'vestigial' qauv
Dab tsi yog qhov chaw tshwj xeeb ntawm cov noob ntawm chromosome?
Nyob rau hauv cov noob caj noob ces, ib locus (plural loci) yog ib qho tshwj xeeb, qhov chaw ruaj khov ntawm chromosome qhov twg ib qho gene lossis cov cim caj ces nyob
Homologous series piv txwv yog dab tsi?
Ib homologous series nyob rau hauv cov organic chemistry yog ib pab pawg ntawm cov organic tebchaw (compounds uas muaj C atoms) uas sib txawv ntawm ib leeg los ntawm ib pawg methylene (CH2). Piv txwv li, methane, ethane, thiab propane yog ib feem ntawm homologous series
Qhov txawv ntawm homologous thiab nonhomologous recombination yog dab tsi?
Qhov sib txawv tseem ceeb ntawm homologous thiab non-homologous chromosomes yog tias homologous chromosomes muaj alleles ntawm tib hom noob nyob rau hauv tib loci whereas non-homologous chromosomes muaj alleles ntawm ntau hom noob
