Question 28
Take out a piece of paper and pencil to solve the Dihybrid cross.
Rabbits have two unlinked allele pairs that affect fur color. The table shows how allele pairs affect fur color. The term “agouti” describes fur with pigmentation that gives the fur a banded appearance.
Rabbits with the aa allele pair are albino, regardless of the second allele-pair combination.
What is the probability of albinism in the offspring of a cross between two rabbits with AaBb alleles?
a
1/16
b
3/16
c
4/16
d
9/16
Question 29
A farmer is breeding two different types of plants with varying patterns of inheritance. For Plant Type A, the allele for red petals is (R) and the allele for white petals is (r). The farmer crosses a homozygous red plant with a homozygous white plant. For Plant Type B, the alleles for both red (R) and white (W) petal color are dominant. The farmer crosses a homozygous dominant red plant with a homozygous dominant white plant. The results of the farmer's crosses are shown in the Punnett squares.
What are the inheritance patterns for each of the plant types?
a
Plant Type A shows a complete dominance pattern of inheritance, and Plant Type B shows a recessive pattern of inheritance.
b
Plant Type A shows a recessive pattern of inheritance, and Plant Type B shows a complete dominance pattern of inheritance.
c
Plant Type A shows an incomplete dominance pattern of inheritance, and Plant Type B shows a codominance pattern of inheritance.
d
Plant Type A shows a codominance pattern of inheritance, and Plant Type B shows an incomplete dominance pattern of inheritance.
Question 30
Directions: The table lists the hair color and genotype of six individuals where black hair is dominant over blond. Use the table to answer any questions that follow.
HAIR COLOR
Name Hair color Alleles
Mr. Johnson black homozygous
Mrs. Johnson blond homozygous
Mr. Valdez blond heterozygous
Mrs. Valdez black heterozygous
Mr. Ellwood black heterozygous
Mrs. Ellwood blond homozygous
If Mr. and Mrs. Johnson had four children together, what color of hair would the children likely have?
a
All 4 of the children would have black hair.
b
Only 3 of the children would have black hair, and 1 child would have blond hair.
c
All 4 of the children would have blond hair.
d
Only 2 of the children would have black hair, and 2 of the children would have blond hair.
Question 31
Determining the clinical course in patients with viral or bacterial infection for acute cough — NIHR Community Healthcare MICYou are sick with a sore throat and fever. Your doctor does a throat swab and makes a microscope slide. Under the microscope, they find long chains of spherical cells that lack membrane bound organelles.
Do you have a viral or bacterial or fungal infection? How do you know?
a
You have a viral infection, as viruses form long cellular chains unique to your cells.
b
You have a bacterial infection, as bacteria are simple prokaryotic cells - and you are not.
c
You have a fungal infection, as fungi are simple prokaryotic cells - as are you.
d
Impossible to determine from the information supplied.
Question 32
Viruses are often referred to as non-living infectious particles as they lack many characteristics of living organisms like cellular structure. They do not have the ability to carry out reproduction and metabolism without a host cell.
True or False and why?
a
False - viruses, like bacteria, do not have a cellular structure and yet, bacteria are considered living organisms.
b
True - if a living organism requires a cellular structure, even if they can reproduce - they are by definition non-living.
c
False - viruses do have a clear cellular structure, including a cell membrane called an envelope.
d
False - viruses are able to reproduce and use energy without a host cell.
Question 33
The table lists the diameters of common viruses and bacteria. A single micrometer (µm) is equivalent to 1000 nanometers (nm).

Using the table as evidence, which argument can be made about the size of viruses compared to the size of bacteria?
a
Bacteria are smaller than most viruses.
b
Viruses are smaller than most bacteria.
c
Bacteria and viruses are about the same size.
d
Viruses are both smaller and larger than bacteria.
