Law of Dominance
i. Characters are controlled by discrete units called factors.
ii. Factors occur in pairs.
In a dissimilar pair of factors one member of the pair dominates (dominant) the other (recessive).
The law of dominance is used to explain the expression of only one ofthe parental characters in a monohybrid cross in the F1 and the expressionof both in the F2. It also explains the proportion of 3:1 obtained at the F2.
