The document discusses different types of DNA markers used for genetic identification and analysis. It describes morphological, protein, and molecular markers. Molecular markers are further divided into types I and II. Type II markers like microsatellites are highly polymorphic and useful for analysis. The document outlines various applications of DNA markers like identification of genetic variations, phylogenetic relationships, and monitoring of inbreeding. It also discusses properties of good markers and institutions conducting research on DNA markers in India.
