Hauv noob caj noob ces , theoretical qhov tshwm sim tau siv rau xam qhov zoo li cov xeeb ntxwv yuav ua ib tug poj niam txiv neej, los yog cov xeeb ntxwv yuav tau txais ib qho kev zoo lossis kab mob yog tias txhua qhov txiaj ntsig tau sib npaug. Nws ua tau kuj siv tau rau xam qhov yuav tshwm sim ntawm qhov zoo ntawm cov neeg coob.

Yog li ntawd, Mendel txoj cai lij choj cuam tshuam li cas rau qhov tshwm sim?

Cov kev cai ntawm kev cais thiab qhov tshwm sim yog raws li cov xwm txheej random. Lub caij nyoog uas ob yam xwm txheej yuav tshwm sim ua ke thaum lub sij hawm meiosis yog txiav txim raws li lwm yam kev tshwm sim random (yob ntawm tsuav, npib tos, thiab lwm yam)

Tom qab, lo lus nug yog, dab tsi yog txoj cai khoom ntawm qhov tshwm sim? Ib txoj cai yuav tshwm sim uas tseem ceeb heev nyob rau hauv noob caj noob ces yog cov txoj cai khoom , uas hais tias cov qhov tshwm sim ntawm ob (lossis ntau dua) cov xwm txheej ywj pheej uas tshwm sim ua ke tuaj yeem suav tau los ntawm kev sib npaug ntawm tus neeg Qhov yuav tshwm sim ntawm cov xwm txheej.

Dhau li ntawm qhov no, qhov tshwm sim yuav cuam tshuam li cas los ntawm noob neej?

1: Lub luag haujlwm ntawm qhov tshwm sim Kev sib cais ntawm alleles thiab fertilization: Hauv a caj ces cross, cov qhov tshwm sim ntawm tus cwj pwm tseem ceeb tau qhia yog nyob ntawm nws qhov zaus. Nyob rau hauv cov ntaub ntawv no, ob leeg niam txiv muaj ib tug tseem ceeb thiab ib tug recessive noob rau qhov zoo ntawm paj xim.

Qhov tshwm sim yog dab tsi thiab nws siv li cas hauv cov noob caj noob ces?

Qhov yuav tshwm sim yog qhov muaj feem yuav tshwm sim. Txoj kev uas alleles segregate yog kiag li random zoo li npib npib. Cov ntsiab cai ntawm qhov tshwm sim tuaj yeem yog siv los kwv yees qhov tshwm sim ntawm noob caj noob ces hla.
