Who might want to take this course?

  • People affected by or concerned about a genetic disease (either directly or in a family member)
  • People interested in the genetic diversity of humans or other species
  • People who have had (or are considering having) their genes or genomes analyzed by companies such as 23andMe
  • People concerned about the public use of personal genetic information
  • People interested in breeding animals or plants, or in in conservation of endangered species
  • People interested in genealogy and ancestry analysis
  • Science teachers
  • Anyone interested in genetics but unable to enroll in university at this time


Beginning with the November 2013 session, Useful Genetics will be taught in two 6-week parts.  Signing up for this session will only enroll you in Part 2, so you may want to also sign up for the separate course Useful Genetics Part 1.

Part 1.  Genes and their effects
(taught as the separate course Useful Genetics Part 1)

Week 1. How different are we?  Introduction to DNA, genes and chromosomes and the relationships between human populations.

Week 2. How DNA molecules change.  The causes and immediate consequences of mutations.

Week 3. DNA differences and gene functions.  How mutations that change gene activity or function affect the properties of organisms.  How mutations cause cancer.

Week 4.  Natural genetic variation.  Sex determination and genes on sex chromosomes. How natural genetic variation is studied, and how it differs from classical alleles. Heritability and genome-wide association studies.  Genetic variation for cancer risks.

Week 5.  Personal genomics.  Kinds of DNA typing and genome analysis, and what can be learned from them about health risks, personal attributes and ancestry.

Part 2.  Inheritance

Week 6.  The mechanics of inheritance.  How genes and chromosomes are transmitted through the generations (including the molecular mechanisms of mitosis and meiosis).

Week 7.  Genetic analysis.  Using genetic crosses as a research tool to investigate how genes work and what they do.  Sex-linkage, pedigree analysis, and hypothesis testing.

Week 8. All about breeding and inbreeding.  More about heritability and GWAS. Inbreeding in humans, crops and livestock, and evolution. Hybrids and genetically modified organisms.

Week 9.  Chromosomal changes.  Polyploidy and aneuploidy, chromosome rearrangements, and genome evolution.

Week 10.  Selected advanced topics.  The origin of life, mitochondrial genes and mutations, genetic mosaicism, fetal DNA in mothers, epigenetic inheritance, and other topics students may suggest.





This college-level course gives students a thorough understanding of gene function and inheritance, and enables them to apply this understanding to real-world issues, both personal and societal. This is Part 2 of a two-part course.
