Ntawm no, ob hom uas tsis yog Mendelian qub txeeg qub teg yog dab tsi?

Feem ntau, thiaj li hu ua tsis yog - Mendelian qub txeeg qub teg tuaj yeem raug ntaus nqi rau qhov nyuaj ntawm cov noob muaj nuj nqi, tsis yog kev sib kis ntawm cov noob. Yog li, tsis tiav penetrance, polygenic qub txeeg qub teg , thiab sib txawv ntawm kev nthuav qhia txhua yam tshwm sim forms tsis - Mendelian qub txeeg qub teg rau thaum ntxov geneticists.

Ib yam li ntawd, tsis yog Mendelian txoj kev xav ntawm kev qub txeeg qub teg yog dab tsi? Tsis yog - Mendelian qub txeeg qub teg yog tej qauv ntawm qub txeeg qub teg nyob rau hauv uas traits tsis cais raws li Mendel cov kev cai. Cov cai no piav txog qhov qub txeeg qub teg ntawm cov yam ntxwv txuas rau tib cov noob ntawm chromosomes hauv lub nucleus.

Piv txwv li, dab tsi yog qhov piv txwv ntawm tsis yog Mendelian qub txeeg qub teg?

Tsis yog - Mendelian traits yog traits uas yog tsis yog dhau los nrog cov tseem ceeb thiab recessive alleles los ntawm ib lub noob. Cov yam ntxwv ntawm polygenic raug suav hais tias tsis yog - Mendelian vim lawv cov alleles nyob ntawm ntau tshaj ib lub noob uas tso cai rau ntau alleles thiab phenotypes. Piv txwv ntawm polygenic zoo yog cov plaub hau xim thiab qhov siab.

Yam dab tsi uas tsis yog Mendelian qub txeeg qub teg ua rau tib neeg qhov muag xim ua piv txwv?

Complex Forms ntawm Keeb kwm Tsis tas li ntawd, kev ywj pheej assortment ua kom cov noob sib xyaw sib txawv hauv gametes. Yog li ntawd, ntau qhov sib txawv nruab nrab phenotypes muaj nyob hauv cov xeeb ntxwv. Qhov muag xim (Daim duab hauv qab no), thiab daim tawv nqaij xim yog cov piv txwv ntawm polygenic zoo nyob rau hauv tib neeg.
