Being able to roll your tongue is dominant over not rolling the tongue. Those who can roll their tongue express the trait.
Create a pedigree for this family:
father - can roll toungue
mother - can not roll toungue
daughter - can not roll toungue
son - can roll tounge
daughter 2 - can roll tounge

Human blood types are determined by genes that follow the codominance pattern of inheritance. There are two dominant alleles (IA and IB) and one recessive allele (i).
What would be the genotype of a person with type A blood who had a father who was type O?
IAi
