Penetrance hauv noob caj noob ces yog qhov kev faib ua feem ntawm cov tib neeg uas muaj qhov txawv txav ntawm cov noob uas tseem qhia txog qhov cuam tshuam.
txhais li cas los ntawm caj ces penetrance?
Penetrance ntsuas qhov feem ntawm cov tib neeg hauv cov pej xeem uas muaj cov noob tshwj xeeb thiab qhia txog qhov muaj feem cuam tshuam.
kev nkag mus thiab kev nthuav tawm yog dab tsi?
Penetrance yog siv los piav qhia seb puas muaj lossis tsis muaj kev kho mob ntawm cov genotype hauv tus neeg. Kev nthuav qhia yog lo lus uas piav qhia qhov sib txawv ntawm kev soj ntsuam phenotype ntawm ob tus neeg uas muaj tib hom genotype.
Koj tuaj yeem txhais li cas kev nkag mus?
Mloog cov lus. (PEH-neh-trunts) Piav qhia yuav ua li cas yog tias tus neeg uas muaj qee yam kab mob ua rau kev hloov pauv (hloov) hauv cov noob yuav qhia cov tsos mob thiab cov tsos mob ntawm tus kab mob. Tsis yog txhua tus uas muaj kev hloov pauv yuav tsim tus kab mob.
Dab tsi ua rau noob nkag mus?
Mutation hom thiab penetrance. Kev nkag mus tsis tiav yuav yog vim qhov cuam tshuam ntawm hom kev hloov pauv. Qee qhov kev hloov pauv ntawm tus kab mob no tuaj yeem pom kev nkag mus tau tiav, qhov twg ib yam li lwm tus hauv tib lub noob qhia tsis tiav lossis qis heev.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers.

Nyob rau hauv noob caj noob ces yog dab tsi genotype ntawm hh txhais tau tias?
Lub hauv paus ntawm lo lus no txhais tau tias "tseem" thiab lawv yog tib yam. HH yog ob lub peev thiab hh yog ob qho tib si qis. HH yog homozygous dominant, vim yog lub peev. HH homozygous recessive? Ib lub taub hau tag nrho cov plaub hau yog qhov tseem ceeb, nrog rau homozygous gene ntawm HH.
Dab tsi yog recessiveness hauv noob caj noob ces?
Kev tsis txaus ntseeg, hauv cov noob caj noob ces, qhov tsis ua tiav ntawm ib khub ntawm cov noob caj noob ces (alleles) tam sim no hauv tus neeg los qhia nws tus kheej hauv kev saib xyuas vim muaj kev cuam tshuam ntau dua, lossis dominance, ntawm nws opposite-acting khub.
Nyob hauv noob caj noob ces palindromes xa mus?
Palindrome: Hauv cov noob caj noob ces, a DNA lossis RNA qib uas nyeem tib yam hauv ob qho lus qhia. Cov chaw ntawm ntau qhov txwv enzymes uas txiav (txheej) DNA yog palindromes. Palindrome hauv caj ces yog dab tsi? Abstract. Lub palindrome hauv DNA zoo li lub palindrome hauv cov lus, tab sis thaum nyeem rov qab, nws yog ib qho ntxiv ntawm cov kab ke pem hauv ntej;
Dab tsi yog cov noob caj noob ces?
hom kab mob lom neeg yog cais tawm ntawm ib leeg. Lub ntsiab txhais yog qee zaum txuas ntxiv kom xav tau tias qhov kev yug me nyuam yuav tsum tshwm sim nyob rau hauv ntuj, tsis yog khoom tsim (xws li, raug ntes). Evolution of reproductive isolating mechanisms tiv thaiv hom nascent los ntawm interbreeding.
