The entire activity must be completed within the period given unless arrangements have been made with
the teacher IN ADVANCE.
All work must be completed in class time. Extra reading and research can be done at home but is not
mandatory. The experiment sheets will be kept at school.
Your task for this investigation is to:

DAY 1 – Wednesday, Dec 12th: Create a concept map that explores the information and
concepts that are a part of your investigation. This will require research and reading.

DAY 2–Thursday, Dec 13th: Write a hypothesis for your investigation. Identify the variables.
Design a procedure for the experiment you will be conducting.

DAY 3– Friday, Dec


14th: Conduct the experiment; collect and organize the data you obtain.
DAY 4– Monday Dec 17th : Complete data gathering; graph your results.
DAY 5–Tuesday Dec 18th: Analyse your results and write a complete conclusion.

the unit reviews to practice!
UNIT 1 Genetic Continuity
 cell cycle
 mitosis and meiosis—purpose, phases, differences
 Mendel’s Law of Segregation and Law of Independent Assortment
 know and apply terms used in genetics: gene, allele, chromosome, chromatids, DNA, dominant, recessive, homozygous,
heterozygous, homologous, phenotype, genotype, monohybrid cross, dihybrid cross, purebred, hybrid, , F1 generation, F2
generation, incomplete dominance, multiple alleles
 #’s and types of chromosomes in males/females, gametes/somatic cells
 solving problems in genetics using the Punnett square
1.
a. Draw a cell 2n = 8 in prophase of meiosis 1. Label spindle fibres, chromosomes, centrioles. How many chromatids? How
many homologous chromosomes? What event occurs in this stage? How many chromosomes would an organism with this cell
have in each of its gamete cells at the end of meiosis?
b. Describe each phase of meiosis.
c. Explain the importance of meiosis.
2. In peas, the allele for tall plants (T) is dominant over the dwarf allele (t).
a) If you cross a homozygous tall plant and a short plant what will the genotype and phenotype of the offspring be?
b) Determine the F2 genotype and phenotype.
3. In peas, the allele for purple flower colour (P) is dominant over the allele for white flower colour (p). Tall plants are dominant to
dwarf plants. Cross a purebred tall purple plant with a purebred dwarf white plant. What are the F1 and F2 phenotypic ratios?
4. Black is dominant to brown in guinea pigs while short hair is dominant to long. Cross 2 heterozygous black, heterozygous short
guinea pigs and determine the frequency of having brown pigs with short hair.
5.
Colourblindness is sex-linked. What are the chances that a colourblind man will have a colourblind son if he has a child with a
woman with no history of colourblindness. Show the cross.
6.
a. Cross a heterozygous type A with a type O blood.
b. What type of blood can a type A person receive? Which blood types can receive type O blood?
UNIT 2: Evolution
1. What evidence is there for evolution? Explain.
2. What are the conditions for Hardy-Weinberg equilibrium?
3. Describe the main points of Darwin’s theory of evolution by natural selection.
4. Provide an example for each of the following: a) directional selection, b) stabilizing selection, c) disruptive selection, d) sexual
selection
5. What is the current definition of species? What mechanisms exist to prevent species from exchanging genetic information?
6. Name and briefly describe allopatric and sympatric speciation
