This book is a compilation of cytogenetic and molecular cytogenetic techniques that are routinely performed in a molecular cytogenetic laboratory. It provides a summary of chromosomal disorders and mechanisms, along with pictures and details of laboratory procedures. Due to the simplicity of the language used, the principles and techniques discussed here are easily understandable. The book also details modern techniques, which will be of interest for geneticists, academicians, scientists, and clinical geneticists aspiring to establish a molecular cytogenetic lab. It also serves to help geneticists understand each protocol as it is written in a self-explanatory manner for standardizing techniques in their laboratory.
