• Take your review sheet and notes, and check if you
have all necessary notes collected together.
• If any notes are missing, use the on-line PPT’s, text
book, other students’ notes to get missing notes.
• Look over the review topics and notes and check
which topics are the least familiar and most
troublesome for you.
• Get together with a group that is reviewing THE
SAME TOPICS THAT YOU NEED TO MOST REVIEW
ON
• Explain topics to each other and quiz each other
• Answer review questions on ALL REVIEW TOPICS

steps.

steps.

an amino acid? On what molecule do you find
the nucleotides that directly determine an amino
acid?

• Define mutation and differentiate between its two
forms.
• State the law of segregation.
• Differentiate between codominance and incomplete
dominance.
• Name two evidence of evolution and explain how
they provide proof of evolution.
• Cystic fibrosis is carried on the recessive
allele. Normal is dominant. A normal man and a
woman with cystic fibrosis have one CF child and
one normal child. What are the chances that
their next child will have cystic fibrosis?
• In peas, tall is dominant to short. If a pure tall
and a pure short plant are crossed, and the
resulting offspring are crossed, how many of the
F2 will be short if 120 plants are produced?
• In guinea pigs, black is dominant to white. If
two black guinea pigs are crossed and 4 black
and 3 white pigs result, were the parents pure?
• In 4 o'clock flowers, red is dominant to white,
but the heterozygote is pink. What is the
phenotype ratio of crossing red 4 o’clock flowers
and pink 4o’clock flowers?
• If Jennifer is normal (and is not a carrier) but her
husband, James, is colorblind, what are the
chances of
A. their daughter, Jean, being colorblind?
B. Of their son, Joe being colorblind?
• List the three types of natural selection and
provide an example of each.
• Describe how DNA can be used as evidence of
evolution.
• In a population, 4 % of all individuals show the
recessive trait. What is the allele frequency of the
dominant allele? What is the frequency of the
heterozygous individuals?
• In a population, 560 out of 1000 individuals show
the dominant trait. What is the frequency of the
recessive allele? Dominant allele? What is the
frequency of the homozygous dominant
individuals?
• In a population of butterflies, the dark coloration
is dominant over the light coloration. What is the
frequency of the recessive allele if 23 out of 67
butterflies are light?
• List 4 mechanisms of evolution and explain how
they change the genetic makeup of the
population.
• Describe how Darwin contributed to the theory
of evolution.

transcription. Describe its function.
• Describe the structure of a ribosome and its
function.
• Why is colorblindness more common in men
than in women?
• Name an example of a vestigial structure. Why
do vestigial structures provide evidence of
evolution?

used by scientists?

using biotechnology.
