In many humans, exposing the skin to sunlight
over prolonged periods of time results in the
production of more pigment by the skin cells
(tanning). This change in skin color provides
evidence that A ultraviolet light can cause mutations.
B the environment can influence gene expression.
C the inheritance of skin color is an acquired characteristic.
D albinism is a recessive characteristic.
Which statement best describes the given diagram?
A Only the fertilized egg contains DNA and the tissue cells do
not.
B Heart, brain, and lung cells are the only types of cells fertilized
eggs produce.
C Cells in fertilized eggs are directed by DNA to become many
types of cells.
D The DNA in fertilized eggs are different than that of cells of
organs.
Which of the following describes the role of RNA in
cell differentiation?
A The RNA determines the type of DNA that will be made.
B The RNA assembles the proteins that are made in a specific
type of cell.
C Each cell has a different set of DNA and RNA that determines
cell type.
D RNA has nothing to do with cell differentiation.
The color of fruit for plant "R" is determined by two
alleles. When two plants with orange fruits are
crossed the following phenotypic ratios are present
in the offspring: 25% red fruit, 50% orange fruit,
25% yellow fruit.
What are the genotypes of the parent orangefruited plants?
This is an example of what type of inheritance?
A cross between a black cat & a tan cat produces a
tabby pattern (black & tan fur together).
What pattern of inheritance does this illustrate?
What percent of kittens would have tan fur if a
tabby cat is crossed with a black cat?
Kanye and Kim are having a baby. Kanye’s
genotype is IᴮIᴮ. Kim’s genotype is ii.
What are the possible options for the baby’s blood
type?
Hairy ears are an x-linked recessive trait in
humans. If you mate a homozygous hairy ear
female with a normal male:
What are the expected offspring genotypes and
phenotypes and their ratios?
What does a female’s genotype have to be in
order to express the disease?
What does a female’s genotype have to be in
order to be a carrier of the disease?
What does a males’ genotype have to be in order
to express the disease?
Can a male be a carrier of an X-linked recessive
trait?
Hemophilia has played an important role in
Europe’s history, for it suddenly cropped up in the
children of Great Britain’s Queen Victoria. It
became known as the “Royal disease” because it
spread to the royal families of Europe through
Victoria’s descendants. One of her descendants,
Alice of Athlone, had one hemophilic son (Rupert)
and two other children—a boy and a girl—whose
status is unknown.
What is the probability
that her other son was
hemophiliac?
Where is the chromosomal abnormality in
the above karyotype?
What occurred during meiosis that would
have caused this abnormality?
Nondisjunction – Homologous chromosomes
Not separating in meiosis
Describe two processes that occur during meiosis
that increase genetic variation?
How would the DNA fingerprints of identical
twins compare to that of fraternal twins?
Where does a mutation have to occur in order for it
to be inherited by the offspring?

Which of the above structures is
evidence of adaptative radiation?
Which of the above structures is
evidence of convergent evolution?
