Module 1

A patient blood type being ABO is an example of a ______________.

Phenotype

A patients inheritance of being AO or AA from mom and dad is called a __________ characteristic.

Genotype

Based on parent genotypes of AO and AA, all of their offsprings will be type ___________.

A

Based on the parent genotypes of AO and AA, the percentage of offspring with the genotype of AA is ______%.

50%

How many pairs of chromosomes does a human have encompassing their genetic code?

23 chromosomes

Multiple alleles can can be found on the same locus. Ture or False?

True

Knowing that O is recessive,  choose the following genotype-phenotype combinations that are correct.

BO-O

OO-O

AO-A

BO-B

OO-O

Correct answer:

AO-A

Correct answer:

BO-B

Based on the parents' genotypes, select all of the potential offspring phenotype outcomes.

You are selecting a unit to transfuse into a type AB patient. Select all blood groups that would be considered compatible for this patient.

B, A, O and AB

Select all of the HETEROZYGOUS genotypes.

AO and AB

A person who inherits identical alleles is
called…

homozygous ; AA, BB

Select all of the HOMOZYGOUS genotypes.

AA, OO, and BB

A person who inherits different alleles is
called

heterozygous ; AO, AB

The AB genotype is an example of a ______________________ phenotypic relationship between the genetic expression of antigens.

recessive

dependent

codominant

homozygous

Which blood type is the Universal recipient?

Type AB

(Has no Ab and has both A and B antigen!)

Which blood type is the Universal donor?

Type O

(O negative, more specifically)

_________ is used to predict the probability of an offspring’s genotype.

Punnett square
