BIOL 2341
Introduction to Genetics

3.0 Credits


In this introduction to a fascinating and controversial area of contemporary science, students are presented with basic terms, principles, and research methods used in the study of genetics. Students learn about the transmission, distribution, arrangement, and alteration of genetic information and how it functions and is maintained in populations.

Delivery Method



Recommended: BIOL 1113, 1115, 1213, or 1215 or equivalent and BIOL 2131.


  • Relate the structure and function of the DNA molecule to its functional role in encoding genetic material.
  • Apply the principles of inheritance as formulated by Mendel.
  • Apply the principles of extensions to Mendelian inheritance, including multiple allelism, lethal alleles, gene interactions, and sex-linked transmission.
  • Analyze genetic data using statistical procedures.
  • Describe normal chromosome number, structure, and behaviour in human cells, and understand the cause and effect of alterations in chromosome number and/or structure.
  • Understand how to identify and classify mutations in DNA.
  • Describe the basic aspects of the flow of genetic information from DNA to proteins.
  • Explain and make deductions about gene regulation with emphasis on the lac operon model.
  • Deduce the relationship between genetic, physical, and cytogenetic maps.
  • Illustrate how information generated by genome sequencing projects can be used to discover practical knowledge about gene expression and relationships between species.
  • Apply the Hardy-Weinberg Law in analyzing population genetics for gene frequency, sex linkage, equilibrium, and heterozygote frequency.
