Cov niam txiv muaj ntshav hom A thiab B puas tuaj yeem muaj menyuam nrog O?
Yog lawm, vim txhua tus neeg muaj ob 'genes' rau hom ntshav. Yog li ntawd, ob tug niam txiv uas muaj hom ntshav A lossis B, yog li ntawd, tuaj yeem tsim tau tus menyuam muaj ntshav hom O. Yog tias lawv ob leeg muaj AO lossis BO noob, txhua tus niam txiv tuaj yeem pub cov noob O rau cov xeeb ntxwv. Tom qab ntawd cov xeeb ntxwv yuav muaj OO noob, ua rau lawv cov ntshav hom O
