Genetics is the branch of biological sciences that investigates the organization, transmission, variation, and functional consequences of hereditary information in organisms. It focuses on the structure and function of genes and genomes, the molecular mechanisms of DNA replication, transcription, and translation, and the regulation of gene expression across developmental and environmental contexts. Genetics encompasses classical (Mendelian) inheritance, molecular genetics, population and quantitative genetics, and genomics, providing the framework for understanding mutation, recombination, genetic linkage, and evolutionary change, as well as informing experimental design and interpretation in biomedical, agricultural, and model-organism research.
A team led by bioengineers at the University of California San Diego has developed a genome-scale reference map that details how individual genes control the functions and identities of human stem cells. This open-access ...
