“Principles of Genetics” is a core foundational course in Agricultural Sciences covering the historical development of genetics, Mendelian laws of inheritance, gene interactions, chromosome morphology and cell division, DNA replication, gene regulation, quantitative genetics, and mutation breeding. This comprehensive PDF study note is designed for B.Sc. Agriculture students and competitive exam aspirants preparing for ICAR JRF, MCAER PG CET, and IBPS AFO.
