• Type A

• Type B

• Type BB

• Type AB

• Type O

What 3 alleles are responsible for the phenotypic expression of ABO Blood types?

• I^A

• I^B

• I^D

• i

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

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

• I^BI^B or I^Bi

• I^AI^A or I^Ai

• I^AI^B

• ii

if the father is type A and the mother is type B, in order for baby Sylvester to have the genotype ii, his parents must be?

• heterozygous

• homozygous

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.
