12-3 OtherPatternsofInheritanceNOTES/?s

Multiple Choice

Which of the following best describes an exception to Mendel’s principles?

• Traits controlled by a single gene with two alleles

• Traits influenced by multiple genes

• Traits that are not inherited

• Traits that do not change over generations

Multiple Choice

Which of the following best describes the difference between incomplete dominance and codominance?

• Incomplete dominance results in a blend of traits, while codominance results in both traits being distinctly expressed.

• Incomplete dominance results in both traits being distinctly expressed, while codominance results in a blend of traits.

• Both incomplete dominance and codominance result in only one trait being expressed.

• Both incomplete dominance and codominance result in no traits being expressed.

Multiple Choice

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

• multiple genes

• multiple alleles

• codominance

• polygenic traits

Multiple Select

Select the statement that is INCORRECT about the inheritance of human blood types based on the genotypes shown.

• Type A blood can have genotype AA or AO.

• Type B blood can only have genotype BB.

• Type O blood can only have genotype OO.

• Type AB blood has both A and B alleles.

Multiple Choice

Which blood type can receive blood from all other blood types?

• A

• B

• AB

• O

Multiple Choice

Which glycoprotein is present on the surface of a cell with the B allele?

• A glycoprotein

• B glycoprotein

• Both A and B glycoproteins

• No glycoprotein

Multiple Choice

What happens to the surface glycoproteins of a cell that has both A and B alleles?

• Only A glycoprotein is present

• Only B glycoprotein is present

• Both A and B glycoproteins are present

• No glycoprotein is present

Multiple Choice

Which blood types will recognize A-type donor blood as 'like me'?

• A and AB

• B and O

• A and O

• B and AB

Multiple Choice

Which blood type is considered the universal recipient and why?

• Type O, because it has no antigens

• Type AB, because it can receive from every blood type

• Type A, because it has A antigens

• Type B, because it has B antigens

Multiple Choice

Which of the following statements about polygenic traits is correct?

• Polygenic traits are influenced by a single gene.

• Polygenic traits show a wide variety of phenotypes.

• Polygenic traits only affect eye color.

• Polygenic traits do not influence hair color.

Multiple Choice

Which of the following best explains why feather color in parakeets is controlled by multiple genes?

• It allows for a greater variety of feather colors.

• It ensures all parakeets have the same color.

• It prevents mutations from occurring.

• It limits the number of possible feather colors.

Multiple Choice

Which of the following is NOT a Non-Mendelian pattern of inheritance?

• Incomplete dominance

• Codominance

• Multiple alleles

• Simple dominance
