  Introduction Every living organism carries a unique genetic blueprint known as DNA (Deoxyribonucleic Acid) , which stores the hereditary information responsible for growth, development, and biological characteristics. Except for identical twins, no two individuals have exactly the same DNA sequence. This remarkable uniqueness forms the foundation of DNA fingerprinting , one of the most significant breakthroughs in modern molecular biology and forensic science . DNA fingerprinting, also known as DNA profiling or genetic fingerprinting , is a laboratory technique used to identify individuals by analyzing specific regions of their DNA that vary from person to person. Rather than examining the entire genome, scientists focus on highly variable DNA markers that create a distinctive genetic profile for each individual. This profile can be compared with DNA obtained from biological samples such as blood, saliva, hair roots, semen, skin cells, bones, plant tissues, or seeds to determine...

Conventional and Molecular Plant Breeding: Complete Guide to Modern Crop Improvement, DNA Markers, MAS, Genomic Selection & Future Technologies (2026) Introduction to Plant Breeding and the Evolution of Crop Improvement Reading Time :  35–45 Minutes Difficulty Level : Beginner to Advanced Last Updated : July 2026 Category : Plant Breeding | Molecular Biology | Biotechnology | Genetics Quick Summary Plant breeding is the science and art of developing improved crop varieties with desirable characteristics such as higher yield, improved nutritional quality, resistance to diseases and pests, tolerance to environmental stresses, and better adaptability to changing climatic conditions. Over thousands of years, plant breeding has evolved from simple farmer-led selection of superior plants to sophisticated molecular breeding techniques that use DNA markers, genomic information, and artificial intelligence. Traditional or conventional breeding relies primarily on observab...
