WebGenetic variance has three major components: the additive genetic variance, dominance variance, and epistatic variance. [3] Additive genetic variance involves the inheritance of a particular allele from your parent and this allele's independent effect on the specific phenotype, which will cause the phenotype deviation from the mean phenotype.
