c) 4 haploid offspring cells
d) 2 haploid offspring cells
II. True/False Questions (EACH question is worth 4 points)
Directions: After reading each statement below, decide if the state is true or
false. Write in the full word TRUE or FALSE in the space provided.
1. ______ Mendel’s Law of Independent Assortment states that factors for
different characteristics are distributed to gametes independently.
2. ______ Phenotype is the genetic makeup of an organism.
3. ______ The cell cycle consists of growth, development and reproduction of a
cell.
4. ______ Asexual reproduction is allows for more genetic variation between
cells.
5. ______ An example of a “test-cross” would be AABB X AaBb.
III. Short Answer Questions (EACH question is worth 10 points)
Directions – For each of the following questions below, use your knowledge
discussed in class about cell division and genetics to answer each question to
the best of your ability. If a punnett square is needed to answer the question, be
sure to COMPLETELY fill it in.
1. The trait in the pedigree below is inherited as a simple recessive. It is very
rare in the general population, so assume that anyone who marries into
the family is homozygous for the normal allele unless there is evidence to
the contrary.
a. What is the probability of the trait appearing in the offspring of
person 1 in the 3rd generation?
b. What is the probability of the trait appearing in the offspring or
person 2 in the 3rd generation?
2. What are the functional differences between meiosis II and mitosis?
Explain your answer and provide pictures if necessary.
3. In peas, yellow (Y) is dominant over green (y), and smooth (R) is
dominant over wrinkled (r). Show the results of crossing a smooth yellow
pea seed heterozygous for both traits with a wrinkled, green pea seed.
What are the phenotypic and genotypic ratios for the first generation of
the offspring?
4. Draw the stages of the cell cycle including the four stages of mitosis. Label
each stage and what is occurring in the cell at that specific point.
