An Introduction to Genetics

This tutorial will take a look at the basic units of genetics, genes themselves, and explore what they are composed of and how they actually work. In particular, this tutorial will explore DNA, the hereditary molecule that allows us to pass on genetic information to our offspring.

This tutorial will explore how genes work together and are passed on from one generation to the next. The concepts of dominant and recessive genes will be introduced alongside how they influence the expression of certain traits. The tutorial will end by taking a look at how geneticists use pedigrees to trace the inheritance and expression of genes across families.

This tutorial will consider how genes behave in large numbers – how they interact with one another as they are copied onto chromosomes. It will then discuss how chromosomes behave and how allele frequencies change in the wild in response to environmental pressures, before moving on to take a brief look at cell biology, population genetics, and quantitative genetics.

Tutorial 7 will discuss the presidency of Ronald Reagan (1981-1989) in the wider context of the resurgence of American conservatism and the rise of the religious right. Tutorial This final tutorial will explore how genes act together in complex systems. It will consider the complex ways in which genes interact, and how they regulate the expression of other genes. Finally, the tutorial will take a look at the recent sequencing of the human genome and the implications that this has for modern medicine and social policy.
