Alleles for the A and B blood cell antigens are co-dominant. The condition where no antigens are present on the blood cells (type O blood) is a recessive trait. Which set of parents can most likely produce a child with type AB blood?

Which of the following genotypes represents a trait that carries homozygous alleles?

A cross between a purebred animal with red hairs and a purebred animal with white hairs produces an animal that has pink hairs. What type of inheritance pattern is involved?

Which of the following genotypes is homozygous dominant?

Situations in which one allele for a gene is not completely dominant over another allele for a gene are called
