5. Qhov twg hauv qab no yuav tsis muaj menyuam? Piav: Tiploids yog inherently sterile; Qhov no yog vim qhov teeb meem hauv meiosis uas tuaj yeem tsim cov diploid thiab unploid. … Nplooj yog ib txwm diploid somatic ntaub somatic uas yuav muab rau tus neeg diploid.
Yuav ua li cas cov hauv qab no yuav ua kom tsis muaj menyuam triploid?
Triploids feem ntau yog autopolyploids. Lawv tshwm sim nyob rau hauv qhov xwm txheej los yog tsim los ntawm geneticists los ntawm crossof a 4x (tetraploid) thiab 2x (diploid). Lub 2x thiab x gametes sib sau ua ke 3xtriploid. Triploids yog tus yam ntxwv tsis muaj menyuam.
Vim li cas triploids tsis muaj menyuam?
triploid Piav txog lub nucleus, cell, lossis kab mob uas muaj peb zaug (3n) tus lej haploid (n) ntawm chromosomes (saib polyploid). Cov kab mob triploid feem ntau yog tsis muaj menyuam raws li lawv tsis muaj homologous chromosomes tiv thaiv kev ua khub thaum meiosis.
Yuav ua li cas yog Monoploid tsis muaj menyuam?
txiv neej muv, nkuaj, thiab ntsaum yog monoploid. … Cov kab mob ntawm cov kab mob monoploid tsis tuaj yeem tshwm sim los ntawm meiosis ib txwm, vim tias cov chromosomes tsis muaj kev sib koom ua ke. Yog li, monoploids yog cov yam ntxwv tsis muaj menyuam. (Txiv neej bees, wasps, thiab ntsaum bypass meiosis; nyob rau hauv cov hom, gametes yog tsim los ntawm mitosis.)
Vim li cas Autoploids feem ntau tsis muaj menyuam?
Autopolyploidy tshwm sim los ntawm ua tsis tiav ntawm chromosomes cais thaum lub sij hawm meiosis … thaum lub sij hawm meiosis. Thaum ob ntawm cov gametes (2n) ua ke, cov xeeb ntxwv tshwm sim yog tetraploid (4n).
