Question #1Question #1What does the term phenotype

mean?

Answer:How a trait appears/looks

Question #2Question #2What does the term genotype

mean?

Answer:The group of genes that make

up a trait (the letters)

Question #3Question #3What does a capital letter

mean?

Answer:It means the allele is dominant

Question #4Question #4If an allele is recessive how

many copies of the allele are needed for it to be expressed?

Answer:Two copies

(aa-one from mom and one from dad)

Question #5Question #5What type of alleles are known

as ‘loud and bossy’?

Answer:Dominant alleles

Question #16Question #16In a certain type of fish there are

three possible alleles; red, orange, and yellow. Orange is the

intermediate of red and orange. Assuming red is R and yellow is Y,

what is the genotype for the orange fish?

Answer: RY

Question #25Question #25In humans, blood type is a classic

example of a trait inherited by multiple alleles. What does

multiple alleles mean?

Answer: There are more than two alleles for a trait (within a population).


example of a trait inherited by multiple alleles. How many different alleles are there?

Answer: 3


example of a trait inherited by multiple alleles. What are the three

alleles possible?

Answer: A, B, and O


example of a trait inherited by multiple alleles. How many alleles

does each person receive?

Answer: 2, one from mom and one from dad

Question #29Question #29Complete the following:

Blood Types ____ and ____ are dominant over Type O

Answer: A and B

Question #30Question #30Complete the following:

Blood Types ____ and ____ are codominantly expressed, meaning

they are expressed together

Answer: A and B

Question #31Question #31What blood type is known as the

universal donor and why?

Answer: Type O blood, because it has no antigens on its surface and therefore can be given to any person

Question #32Question #32What blood type is known as the

universal receiver and why?

Answer: Type AB blood, because it will not react poorly to antigen A or B and a person with this blood type can receive a tranfusion from anyone

Question #33Question #33If a mother is homozygous for type

A blood and a father is heterozygous for type B blood,

what are the chances of having a child with type O blood?

Answer: 0% AB

Question #34Question #34If a mother has type B blood and her son has type O blood is the

mother homozygous B or heterozygous B?

Answer: Heterozygous, because he had to get one O from dad and one O from mom

Question #35Question #35 A woman and her husband claim that

their child was mixed up on the hospital because of its dark hair. The

mother has type B blood and the father has type A blood. The alleged child has type O blood. Should the

parents be concerned?

Answer: No, the mom and dad could both be heterozygous resulting in a child with type O blood.
