Blood-Type Genetics

Blood-Type Genetics

Slide 2

Blood Cell Antigens

Blood Cell Antigens

Blood types are the result of the presence (or absence) of antigens (molecules) on the surface of the individuals red blood cells. These fall into two groups:

A, B, O blood type

Rh factor

Slide 3

Codominance

Codominance

The gene for antigen A and the gene for antigen B are CODOMINANT.

Both traits are expressed completely when the gene for A is inherited from one parent and the gene for B is inherited from the other parent.

Slide 4

Bloodtype antigens and antibodies

Bloodtype antigens and antibodies

Slide 5

A, B, O Inheritance

A, B, O Inheritance

Slide 6

Blood Type Problem

Blood Type Problem

Three children recently born in a hospital were accidently mixed up. The blood types of the parents involved are given along with the blood types of the infants. Determine which baby belongs with which parents, and explain your reasoning for the decisions you made.

Mother and Father _ _Babies _

Parents #1 Type A & Type B Child x Type A

Parents #2 Type O & Type AB Child y Type O

Parents #3 Type B & Type O Child z Type AB

Slide 7

Rh Inheritance

Rh Inheritance

Rh inheritance is independent of A, B, O blood type.

Slide 8

ABO and Rh blood type distribution by nation (population averages)

ABO and Rh blood type distribution by nation (population averages)

Slide 9

Blood Type Problem

Blood Type Problem

A man whose alleles for blood type are A/O and Rh+/Rh- marries a woman whose alleles are B/O and Rh+/Rh-.

What are the phenotypes of the parents with respect to blood type?

What are the possible genotypes for their offspring with respect to blood type?

What are the possible phenotypes for their offspring with respect to blood type?

Slide 10

What are the phenotypes of the parents with respect to blood type?

What are the phenotypes of the parents with respect to blood type?

Father:

AO is expressed as type A

Rh+/Rh- is expressed as Rh+

Fathers phenotype is A+

Mother:

BO is expressed as type B

Rh+/Rh- is expressed as Rh+

Mothers phenotype is B+

Slide 11
