Mendel's law of Dominance is demonstrated by these families.
Explanation:
Mendel's Law of Dominance states that the recessive gene will not be expressed in front of Dominant gene. He found that in a heterozygous gene the allele for Dominant trait will mask the trait expressed by recessive trait, also one trait will overshadow the other trait both the traits will not appear in offspring.
Aa X Aa (In first family both parents are heterozygous)
AA X  aa ( In second family the father is dominant and mother is recessive and albino, but no child will be albino since all would be heterozygous for the trait.)
