For creatures that look nothing like us, fruit flies have been able to teach us a lot about human biology as we’ve studied them over the past century.

In this video Paul Andersen explains how the frequency of recombination between linked genes can be used to determine the relative location of genes on a chromosome. Thomas Hunt Morgan and Alfred Strutevant used the fruit fly to develop...

Paul Andersen explains aspects of genetics that were not covered by Gregor Mendel. He begins with the following topics; incomplete dominance, codominance, epistasis, multiple alleles, and multiple genes. He then explains how linked...

In this video Paul Andersen describes genetics at the chromosomal level. He begins with a simple monohybrid cross as viewed through Mendelian genetics and then shows how genes are distributed through meiosis to possible gametes. This...
