Tom qab ntawd, dab tsi yog heterozygous allele?

Heterozygous txhais tau hais tias lub cev muaj ob yam sib txawv alleles ib gene. Piv txwv li, cov txiv laum huab xeeb tuaj yeem muaj paj liab thiab yog homozygous dominant (liab-liab), lossis heterozygous (liab-dawb). Yog hais tias lawv muaj paj dawb, ces lawv yog homozygous recessive (dawb-dawb). Cov neeg nqa khoom ib txwm muaj heterozygous.

Ib tug kuj yuav nug, piv txwv li homozygous yog dab tsi? Yog hais tias lub cev muaj ob daim ntawv luam ntawm tib allele, rau piv txwv AA or aa, yog homozygous rau qhov zoo. Yog hais tias lub cev muaj ib daim qauv ntawm ob qho sib txawv alleles, rau piv txwv Aa, nws yog heterozygous.
