Qhov sib txawv tseem ceeb ntawm bivalent thiab synaptonemal complex yog tias bivalent yog kev koom tes ntawm txiv neej thiab poj niam homologous chromosomesthaum lub synaptonemal complex yog cov qauv protein tripartite uas tsim ntawm ob homologous chromosomes.
Puas yog bivalent thiab tetrad tib yam?
Bivalent thiab tetrad yog ob nqe lus uas cuam tshuam zoo siv los piav txog chromosomes hauv lawv theem sib txawv. … Yog li, qhov sib txawv tseem ceeb ntawm bivalent thiab tetrad yog tias bivalent yog pawg ntawm ob homologous chromosomes whereas tetrad yog pab pawg ntawm plaub tus muam chromatids hauv homologous chromosome khub.
Dab tsi yog qhov txawv ntawm bivalent thiab synapsis?
Qhov sib txawv tseem ceeb ntawm synapsis thiab hla dhau yog qhov synapsis yog kev sib koom ua ke ntawm homologous chromosomes thaum lub sijhawm prophase 1 ntawm meiosis 1 whereas hla yog kev sib pauv ntawm cov khoom siv caj ces thaum lub sijhawm synapsis.
Yuav ua li cas yog bivalent?
Ib tug bivalent muaj plaub chromatids thiab ob centromeres. Bivalent yog ib khub ntawm homologous chromosome dag ua ke hauv zygotene theem ntawm prophase I ntawm thawj meiotic division.
Dab tsi yog bivalent hauv cell division?
Ib tug bivalent yog ib khub chromosomes (viv ncaus chromatids) hauv tetrad. … Qhov kev sib txuas ntawm lub cev no tso cai rau kev sib haum xeeb thiab kev sib cais ntawm homologous chromosomes hauv thawj qhov kev faib meiotic.
