What is an invasive species?
When an effective insecticide is used on a population of insects, most of the insects are killed.
However, a few may survive due to genes that make them resistant to the insecticide. What is the BEST
explanation of why this occurs?

How could you identify DNA ‘vs’ RNA in a diagram?
How is DNA like RNA? How is it different?
If a scientist is trying to decide if a molecule is RNA or DNA, for what should he/she test?
In DNA, what can be said about the amount of thymine (T) as compared to the amount of adenine (A)
34. and the amount of cytosine (C) as compared to guanine (G)?
What type of mutation has occurred if a DNA sequence that initially reads ATTGCCGAT now reads

A poodle with black fur (BB) is crossed with a poodle with brown fur (bb). Using a Punnett square,
what is the probability that the offspring will be black?
All characteristics are determined by what?
Alleles for different traits are distributed to reproductive cells & offspring independently of one another.
42. This is an example of which of Mendel’s laws?
An organism with the genotype Dd is crossed with an organism of the same genotype. Using a Punnett
square, what is the RATIO of offspring displaying the dominant allele to offspring displaying the
43.
recessive allele?

In a pedigree chart, draw the symbol that represents a male who has a particular trait.
In a pedigree chart, draw the symbol that represents a female carrier.
During the formation of gametes, the two alleles responsible for a trait separate from each other. Alleles
for a trait are then “recombined” at fertilization, producing the genotype for the traits of the offspring.
46.
This is an example of which of Mendel’s laws?
If two first-generation self-pollinating plants are crossed, Pp x Pp, what is the PROBABILITY that
47. offspring plants will show the recessive trait, pp?
If you cross two rabbits that have the genotype Bb, how many possible GENOTYPES can be found in
48. the offspring?
In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next
generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype. This
49.
is an example of which of Mendel’s laws?
In a plant, tall (D) is the dominant allele. Short (d) is the recessive allele. Which GENOTYPE would a
50. short offspring have?
The likelihood that an offspring will have a genetic disorder, such as sickle cell disease, depends on
51. what factors?
What are the possible genotypes of the offspring if you cross a white flower (with the genotype pp) with
52. a purple flower (with the genotype PP)? What would the phenotype be?
