This text provides a balanced coverage of clinical and molecular genetics. Experimental highlights and extensive use of learning aids are used throughout. After a broad introduction to the topic, the book is divided into 3 parts. Part one explores Mendelian genetics including chromosomes and genetic linkage. Part two looks at molecular genetics covering chemistry of a gene, repluation and recombination of genes and transcription and its control in prokaryotes. The final part introduces population genetics and discusses some of their extensions and applications.
