Txoj Cai ntawm Kev ywj pheej Assortment piav seb txawv li cas noob ntawm nws tus kheej cais tawm ntawm ib leeg thaum cov qe ntshav tsim tawm. Kev ywj pheej assortment ntawm noob thiab lawv qhov zoo sib xws tau pom thawj zaug los ntawm Gregor Mendel hauv 1865 thaum nws kawm txog noob caj noob ces hauv cov txiv laum huab xeeb.
Ib yam li ntawd ib tug yuav nug, dab tsi yog kev ywj pheej assortment txhais tau tias hauv noob caj noob ces?
Txhais ntawm ywj siab assortment .: tsim ntawm random ua ke ntawm chromosomes hauv meiosis thiab ntawm noob ntawm cov khub sib txawv ntawm homologous chromosomes los ntawm txoj cai raws li txoj cai ntawm qhov tshwm sim ntawm ib qho ntawm txhua tus diploid khub ntawm homologous chromosomes rau hauv txhua gamete ywj siab ntawm ib leeg khub.
Txoj cai lij choj ntawm Kev ywj pheej Assortment piav qhia nrog piv txwv li cas? Mendel cov Law of Independent Assortment piav qhia qhov qub txeeg qub teg. ntawm ob qhov zoo ntawm cov nroj tsuag ua ke. Qhov no tuaj yeem piav qhia los ntawm kev noj cov piv txwv ntawm qub txeeg qub teg ntawm qhov siab thiab xim ntawm paj ua ke nyob rau hauv pea cog. Hom ntoo khaub lig no yog hu ua dihybrid cross.
Yog li ntawd, txoj cai lij choj ntawm Independent Assortment yooj yim txhais li cas?
npe Genetics. lub hauv paus ntsiab lus, keeb kwm los ntawm Gregor Mendel, hais tias thaum ob lossis ntau tus yam ntxwv tau txais los, ib tus neeg muaj keeb kwm muaj ntau yam ywj siab thaum lub sij hawm gamete ntau lawm, muab qhov sib txawv ntawm qhov sib npaug ntawm qhov tshwm sim ua ke.
Kev ywj pheej assortment tshwm sim li cas?
Kev ywj pheej assortment tshwm sim thaum tus txheej txheem ntawm meiosis. Qhov no yog ib feem tsim nyog ntawm kev sib deev kev sib deev uas tso cai rau ob gamete hlwb tom qab ntawd fuse ua ke los tsim ib tug diploid zygote, muaj tag nrho cov DNA tsim nyog los tsim ib lub cev tshiab.

Dab tsi yog cell cycle hauv genetics?
Lub voj voog ntawm tes yog ib qho xwm txheej uas tshwm sim hauv ib lub xov tooj thaum nws loj hlob thiab faib. Ib lub xovtooj ntawm tes siv sijhawm feem ntau hauv qhov hu ua interphase, thiab lub sijhawm no nws loj hlob, rov ua dua nws cov chromosomes, thiab npaj rau kev faib cell. Tom qab ntawd lub cell tawm ntawm interphase, nkag mus rau mitosis, thiab ua tiav nws qhov kev faib tawm
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog qhov zoo tshaj plaws piav qhia Txoj Cai ntawm Kev ywj pheej Assortment?
Mendel txoj cai lij choj ntawm kev ywj pheej hais tias cov alleles ntawm ob (lossis ntau dua) cov noob sib txawv tau txheeb rau hauv gametes ntawm ib leeg. Hauv lwm lo lus, allele ib gamete tau txais rau ib lub noob tsis cuam tshuam rau allele tau txais rau lwm cov noob
Gene assortment yog dab tsi?
Lub hauv paus ntsiab lus ntawm Independent Assortment piav qhia txog cov noob sib txawv ntawm nws tus kheej sib cais los ntawm ib leeg thaum cov qe menyuam loj hlob. Kev ywj pheej assortment ofgenes thiab lawv cov yam ntxwv sib xws tau pom thawj zaug los ntawm Gregor Mendel hauv 1865 thaum nws kawm txog noob caj noob ces hauv peaplants
Txoj cai lij choj ntawm Kev ywj pheej Assortment piav qhia nrog piv txwv yog dab tsi?
Txoj cai ntawm kev ywj pheej assortment yog nyob ntawm tus ntoo khaub lig dihybrid. Nws hais tias qhov qub txeeg qub teg ntawm ib tus cwj pwm yeej ib txwm muaj kev ywj pheej ntawm qhov qub txeeg qub teg ntawm lwm cov cim hauv tib tus neeg. Ib qho piv txwv zoo ntawm kev ywj pheej assortment yog Mendelian dihybrid ntoo khaub lig
