Genetics II Notes

📘 Genetics II Notes (2026–2027 Edition)

Genetics II Notes (2026–2027 Edition) is an advanced and research-oriented textbook designed for BS students, educators, and professionals in genetics, molecular biology, and biotechnology. This book expands classical genetics concepts and introduces modern areas such as population genetics, evolutionary genetics, genomics, epigenetics, cancer genetics, and advanced genetic technologies.

This book connects theoretical genetic principles with modern laboratory techniques and real-world applications in medicine, agriculture, and biotechnology. It helps students develop strong analytical skills in genetic research, data interpretation, and molecular analysis.
