Kev sib tw tsis sib xws yog qhov tshwm sim uas tib neeg xaiv lawv tus khub raws li lawv cov genotypes lossis phenotypes. Piv txwv ntawm hom mating no tshwm sim nyob rau hauv hom xws li tib neeg, peacocks, thiab qav.
Dab tsi yog random mating?
Kev sib tw tsis sib xws tshwm sim thaum qhov tshwm sim uas ob tus neeg hauv ib pawg neeg yuav ua phooj ywg tsis zoo ib yam rau txhua tus khub ua tau … Inbreeding - cov tib neeg muaj feem ntau nrog kev sib raug zoo cov txheeb ze (xws li lawv cov neeg zej zog) dua li cov txheeb ze nyob deb. Qhov no yog ib yam.
Yuav ua li cas tsis yog random mating quizlet?
tsis sib haum. Yog tias cov pej xeem tsis sib koom ua ke tab sis hloov mates nrog xaiv tus lej, kev sib xyaw ntawm cov genotypes tsis yog random.
Dab tsi yog hom kev sib tw tsis sib xws?
NONRANDOM MATING/INBREEDING
13–16, 59-63, 198-205 •Yuav paub qhov txawv ntawm ob hom kev sib tw tsis sib xws: (1)Assortative mating: mating ntawm tib neegnrog cov phenotypes zoo sib xws lossis ntawm cov tib neeg uas tshwm sim hauv ib qho chaw. (2) Inbreeding: mating ntawm cov neeg txheeb ze.
Puas yog inbreeding piv txwv ntawm tsis random mating?
Ib daim ntawv ntawm kev sib tw tsis sib xws yog kev sib txuas, uas tshwm sim thaum cov tib neeg uas muaj cov genotypes zoo sib xws ntau dua ua phooj ywg nrogib leeg es tsis yog nrog cov tib neeg uas muaj cov genotypes sib txawv.

Cov tub ntxhais kawm theem siab thiab tsev kawm qib siab feem ntau ntsib kev tsis pom kev tsis zoo thaum lawv kawm. Thaum lawv nyeem lawv cov ntawv kawm, cov ntaub ntawv yuav zoo li yooj yim .
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.

Piv txwv ntawm kev tuag metaphors tuag metaphors Ib qho piv txwv tuag yog ib daim duab ntawm kev hais lus uas tau ploj qhov qub duab ntawm nws lub ntsiab lus los ntawm kev siv dav, rov ua dua, thiab siv nrov. Cov lus piv txwv tuag feem ntau yog qhov tshwm sim ntawm kev hloov pauv hauv kev hloov pauv hauv kev hloov pauv ntawm ib hom lus, txheej txheem hu ua kev hais lus ntawm kev ua piv txwv.
Puas yog cov qauv piv txwv zoo ib yam li kev ua piv txwv?
Lub hom phiaj sampling yog siv dav hauv kev tshawb fawb zoo rau kev txheeb xyuas thiab xaiv cov ntaub ntawv nplua nuj cuam tshuam txog qhov tshwm sim ntawm kev txaus siab. Txawm hais tias muaj ntau ntau lub hom phiaj ua piv txwv, cov qauv qauv zoo li tau siv feem ntau hauv kev tshawb fawb siv.
