Linked Genes

This Linked Genes video also includes:

Scholars analyze Morgan's fruit fly lab to learn how genes are linked. The instructor shows that the data from a dihybrid cross was not what Morgan expected, and when re-crossed numerous times, the data did not change. Viewers see gene linkage because the data and visuals show that some genes are linked or found on the same chromosome.
