Chromosomes hla ntawm cov ntsiab lus hu ua chiasma. Ntawm txhua chiasma, cov chromosomes tawg thiab rov koom nrog, ua lag luam qee yam ntawm lawv cov noob. Qhov kev sib xyaw ua ke no ua rau muaj kev hloov pauv caj ces.
Kev hla dhau qhov tsim cov caj ces txawv li cas?
Kev hla dhau yog kev sib pauv ntawm cov khoom siv caj ces ntawm cov tsis yog tus muam chromatids ntawm homologous chromosomes. Nws tshwm sim hauv kev sib txuas tshiab ntawm cov noob ntawm txhua tus chromosome … Nws ua rau gametes uas muaj qhov sib txawv ntawm cov chromosomes. Hauv kev sib deev, ob gametes koom ua ke los tsim cov xeeb ntxwv.
Kev hla dhau yuav ua rau muaj kev hloov pauv li cas?
Hla dhau yog txheej txheem uas tshwm sim ntawm homologous chromosomes txhawm rau ua kom muaj ntau haiv neeg. Thaum hla dhau, ib feem ntawm ib chromosome pauv nrog lwm tus. … Gametes tau txais lub peev xwm los hloov caj ces txawv ntawm lawv cov neeg nyob sib ze gametes tom qab hla tshwm sim.
Kev hla dhau ntawm kev hloov pauv yog dab tsi?
Thaum homologous chromosomes tsim ua khub thaum lub sijhawm prophase I ntawm meiosis I, hla dhau tuaj yeem tshwm sim. Kev hla dhau yog kev sib pauv ntawm cov khoom siv caj ces ntawm homologous chromosomes Nws ua rau muaj kev sib txuas tshiab ntawm cov noob ntawm txhua tus chromosome. … Nws yog qhov pom tseeb ntawm lwm qhov kev hloov pauv caj ces hauv cov xeeb ntxwv.
