3.03: Students will interpret and predict patterns of inheritance, including traits, multiple alleles, polygenic traits, sexlinked traits, independent assortment, test cross, pedigrees, and Punnett squares.
1. If short hair (L) is dominant to long hair (l), then to
determine the genotype of a short hair animal, you
should test cross it with an animal who is
A. LL
C. Ll
B. ll
D. None of these
2. Height and intelligence in humans are examples of
A. incomplete dominance
C. polygenic traits
B. nature versus nurture
D. multiple alleles
3. A lion with gold fur (GG) mates with a jaguar with
black fur (BB). All of their offspring turn out with
striped gold and black fur. What type of dominance
is being demonstrated?
A. Incomplete dominance
B. Codominance
C. Multiple alleles
D. Mendelian inheritance
4. This pedigree shows a sex-linked recessive trait over
three generations in a family. If individual 6 has a
daughter, what will be her phenotype?
A. Normal
C. Affected
B. Carrier
D. Either affected or a carrier
5. Rebecca went to a genetic counselor. They told her that
she is a carrier for the disease sickle cell anemia. She
was normal, but could pass the trait on to her offspring.
Normal red blood cells (N) are dominant to sickle cell
anemia (n). Which of the following would correctly
represent her genotype?
A. NN
B. Nn
C. nn
D. NO
A.Male, normal
B.Male, Down Syndrome
C.Female, Turner’s
syndrome
D.Male; Klinefelter’s
syndrome
8.
In the dihybrid
cross below, how many
offspring will be round
and yellow?
A.
1 out of 16
B.
3 out of 16
C.
9 out of 16
D.
16 out of 16
9. A squash plant that is homozygous dominant for white
fruit (F) is crossed with a plant that is homozygous
recessive for yellow fruit (f). All white fruit offspring
are produced. If these white fruit offspring are crossed
with each other, what is the probability of these
offspring producing white fruit?
A. 25%
B. 50%
C. 75%
D. 100%
10. Some flowers show incomplete dominance. If R’R’ =
white and RR = red, which phenotypic ratio would be
expected in the offspring of one pink and one red
6. Susan, a mother with type B blood has a child with type
flower?
O. She claims that Craig, who has type A blood, is the
A. 1 red : 2 pink : 1 white
father. Further blood tests ordered by the judge reveal
B. 0 red : 4 pink : 0 white
that Craig is AA. The judge rules that
C. 2 red : 2 pink : 0 white
A. Susan is right and Craig must pay child support
D. 4 red : 0 pink : 0 white
B. Craig is right and doesn’t have to pay support
C. Susan cannot be the real mother
D. It is impossible to make a decision
7. Looking at the following pedigree, how would you
classify the individual?
3.04: Assess the impacts of genomics on individuals
and society, including the Human Genome Project
and applications of biotechnology.
11. Scientists have cloned sheep but have not yet cloned a
human. The best explanation for this situation is that
A. There are many ethical problems involved in
cloning humans
B. The technology to clone humans has not been
explored
C. Human reproduction is very different from that of
other mammals
D. Cloning humans would take too long
12. Which process is illustrated in the diagram below?
A.
B.
C.
D.
Selective breeding
Genetic engineering
Therapeutic cloning
Genetically modified crops
Use the diagram below to answer question 3 and 4.
15. How would genetically altering plants for pest
resistance be economically beneficial?
A. Erosion of topsoil would no longer be a concern
B. Crops would be more easily protected from weeds
C. Crop-eating pests would no longer ruin crops
D. Abnormal plant growth would be eliminated
16. The gene for the production of human insulin is inserted
into certain bacterial cells. The offspring of these
bacterial cells will most likely be able to
A. Destroy pathogens
B. Synthesize this hormone
C. Reproduce sexually
D. Form human tissue
17. What is the significance of the Human Genome Project?
A. The cause of cancer was discovered
B. The 3 billion bases in human DNA were discovered
C. The structure of DNA and how it is made was
determined
D. All of the proteins made by human DNA were
discovered
18. Which transplant method would prevent the rejection of
an organ after a transplant?
A. Using organs cloned from the cells of the patient
B. Using organs produced by genetic engineering to
get rid of all proteins in the donated organs
C. Using organs only from pigs or monkeys
D. Using an organ donated by a close relative
