The phenomenon wherein a factor (allele) expresses itself in the presence or absence of its dominant factor, is called dominance. |
It can only express itself in the absence of its dominant factor. |
It forms a complete functional enzyme that perfectly expresses it. |
It forms an incomplete defective enzyme which fails to express itself when present with its dominant allele, i.e., in heterozygous condition. |
