B) Law of Inheritance.....inheritance refers to things passed down from parent to child by genes. The law of inheritance says that alleles for specific traits are passed down from someone’s parents.
There are 3 different alleles: IA, IB and i - IA and IB are codominants, i is recessive. Codominance means neither allele can mask the expression of the other and both alleles A and B are expressed in the blood type.
