Methods Of Instruction
  • Instructor tutoring and lectures
  • Discussion groups
  • Practical applications and lab exercises
  • Self-study via print or online materials
  • Reading and problem solving assignments

This course involves four hours per week of classroom instruction and three hours per week of laboratory activity.  Classroom work will include lectures and tutorials, and is integrated with textbook, scientific journal readings and problem assignments.  The laboratory work is designed to complement the theory content of the course, to develop both specific and general lab skills, and to provide exposure to a variety of organisms commonly used as model systems for the study of genetics.

Course Description
This course is the study of the principles of genetics. Topics covered include the physical and chemical basis of heredity, genetic analysis in eukaryotes, prokaryotes and viruses, mutation; population genetics and evolution

Learning Outcomes

Upon completion of this course, students will be able to demonstrate an understanding of the principles of classical and modern genetics, including being able to:

  1. Describe the physical basis of heredity.
  2. Describe the experimental basis of Mendelian inheritance.
  3. Describe sex-determining mechanisms in a wide variety of organisms.
  4. Describe non-Mendelian inheritance, including linkage, sex-linkage, sex-influenced inheritance, sex-limited inheritance, multiple allelism, polygenic inheritance, and extra-chromosomal inheritance.
  5. Interpret pedigrees to determine modes of inheritance of genetic anomalies in humans.
  6. Derive chromosome maps by a variety of techniques, including the analysis of:
    • testcross data in higher organisms
    • conjugation, transduction and transformation experiments in bacteria
  7. Describe the cytological and biochemical basis of mutation and mutagenesis.
  8. Describe the structure, replication, and functions of nucleic acids.
  9. Describe the process of protein synthesis and the control of protein synthesis in bacteria and in higher organisms.
  10. Describe the genetic control of metabolism.
  11. Describe the genetics of populations, including Hardy-Weinberg equilibrium, genetic drift, the effects of selection on allele frequencies and the evolutionary implications of population genetics.
  12. Perform and interpret genetic experiments with a variety of organisms.
  13. Describe the genetic basis of evolutionary theory.
  14. Use general principles of genetics to discuss current issues.
Means of Assessment

Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:

Assignments and tests 

10-20%
Oral presentation 0-5%
Midterm exams (2) 25-35%
Final comprehensive exam 25-35%
Lab reports  25-30%
Total 100%
Textbook Materials
