There are multiple alleles for the ABO blood group. Why are only two of these alleles present in any one individual?

• Each parent contributes only one allele for the ABO blood group to the offspring.

• There are not enough nucleotides in a red blood cell to produce a third allele.

• Each allele in the ABO group must be dominant or recessive

• Blood group alleles are not segregated during meiosis.

Which term(s) best describes the inheritance of human blood types?

• incomplete dominance and multiple alleles

• codominance and epistasis

• codominance and multiple alleles

• incomplete dominance and codominance

What are the 4 possible phenotypes for human blood type?

• Type A

• Type B

• Type BB

• Type AB

• Type O

Why can someone with type O blood donate blood to everyone?

• because type O blood does have antigens A and B.

• because it doesn't have A or B antigens that would cause it to be attacked by antibodies.

Why can people with AB Blood accept blood from anyone?

• because they don't have any antigens at all

• because they have already both A and B antigens.

If a person has type B blood, the phenotype is B. What can the genotype be?

• I^BI^B or I^Bi

• I^AI^A or I^Ai

• I^AI^B

• ii

What type of inheritance is determined by multiple genes and there can be a range of traits?

• Codominance

• Incomplete dominance

• Polygenic traits

A single gene has 3 or more alleles. These are called

• multiple genes

• multiple alleles

• codominance

• polygenic traits
