Teaching Thursday: Pedigrees

This Thursday’s teaching video is a primer on pedigree analysis.

Even though their use has fallen out of favor, as we begin to better understand the complexity of genetic diseases, a pedigree is still a pretty good place to start as students begin to learn the basics of Mendelian inheritance: autosomal vs sex-linked modes of inheritance, and dominant vs recessive mutations.

Sure, we know the world is a lot more complex than this. But it’s still good to start with relatively simple pedigrees, so we can build from there. Today’s video is a brief introduction to Mendelian genetics and pedigrees.
