Question 9
A cell is growing in size, producing proteins, what phase
of the cell cycle is it in?
Answer: 4’s stand

Interphase
Question 10
What phase of mitosis is the cell in?
Answer:
4’s stand

Metaphase
Question 11
DNA is replicated during which phase of the cell cycle?
Answer: 3’s stand
Table 5
S phase
Question 12
List TWO difference between mitosis and meiosis
Answer: 1’s stand
Table 1
Mitosis- 2 cells, 46 chromosomes, not sex cells
Meiosis- 4 cells, 23 chromosomes, sex cells
Question 13
List the sex chromosomes of a female.
Answer: 4’s stand
Table 6
XX
Question 14
How many chromosomes does a normal human cell
have?
Answer: 2’s stand
Table 4
46 chromosomes
Question 15
During meiosis, chromosomes exchange genetic
material. What is this event referred to?
Answer: 3’s stand
Table 3
Crossing over
Question 16
Having detached earlobes (D) is dominant to attached
earlobes (d). A male and female have four children all
with detached earlobes. The mother knows she is
heterozygous for the trait. What is the genotype of the
father?
Answer: 2’s stand
Table 6
DD
Question 17
What is the difference between genotype and
phenotype? Provide an example.
Answer: 4’s stand
Table 1
Genotype= genes (ex. DD)
Phenotype= appearance (attached earlobes)
Question 18
A large eyed squirrel mates with a small eyed squirrel.
Their young have medium shaped eyes. What type of
inheritance is this?
Answer: 2’s stand
Table 2
Incomplete dominance (blending)
Question 19
In a litter of 8 kittens there are 2 orange, 2 white, and 4
orange and white spotted. What are the phenotypes of
the mother and father?
Answer: 1’s stand
Table 3
Orange and white spotted
Question 20
In turtles, having a textured shell is x-linked (T). Females either have a
textured shell, a smooth shell, or are carriers of the textured shell allele.
Males have either a textured or smooth shell. Suppose a male with a
smooth shell mates with a female carrier. What is the likelihood of there
being a female with a textured shell.
Answer: 4’s stand

Question 21
Occasionally, zebra fish will be born with an extra fin. This is a
recessive disorder controlled by the presence of the appendage
allele A. Two normal zebra fish mate and produce an offspring with
an extra fin. How is this possible?
Answer: 2’s stand
Table 4
The parents are heterozygous (Aa).
Question 22
Alport’s syndrome is an x-linked dominant disorder caused by the
gene that controlled collagen production. The allele for this disorder
is represented by the letter A. A female who is homozygous for this
disorder mates with male who does not have the disorder.
Correctly draw the Punnett square for this cross.
