Introduction to Cytogenetics: Part 1

 

This two-part series provides an introduction to the science of cytogenetics. Cytogenetics is the study of chromosomes, genomic structure, function and variation, and the role of these aspects in human disease and heredity. Explanations will include the basics of technologies of chromosome analysis and karyotyping.
