One paragraph, so you can see how it reads

BIO301 · UNIT 1: POPULATION GENETICS

Population genetics was a vital ingredient in the emergence of the modern evolutionary synthesis. Its primary founders were Sewall Wright, J. B. S. Haldane and R. A. Fisher, who also laid the fo undations for the related discipline of quantitative genetics.

What you should be able to do

  1. Explain the principles of population genetics and factors affecting allele frequencies.
  2. Describe chromosomal aberrations and their genetic significance.
  3. Discuss the mechanisms of genetic variation in plants and animals.
  4. Explain microbial genetics, including replication, transcription, and translation.
  5. Describe biochemical and biomedical genetics, including enzyme deficiencies and structural protein defects.
  6. Apply pedigree analysis to determine inheritance patterns of human genetic disorders.

Where it gets hard

The units students slow down on, and what makes each one heavy.

  • Module 2: Cytogenetics

    Unit 2: Cytogenetics

    Understanding the formation of quadrivalents and their disjunction patterns requires strong visualization skills and spatial reasoning.

  • Module 4: Microbial genetics

    Unit 4: Microbial genetics

    The multiple steps and enzymes involved in the lytic and lysogenic cycles require memorization and understanding of their specific roles.
