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.
Higher yields, greater resilience to climatic changes or diseases—the demands on crop plants are constantly growing. To address these challenges, researchers of Karlsruhe Institute of Technology (KIT) are developing new ...

Gut microbes are essential partners that help digest food, produce vitamins and train the immune system. They can also pass on behavioral traits to their host's offspring, at least in mice. Scientists at the Max Planck Institute ...
Most species on Earth exist as two biological sexes, and the exchange of genes between males and females is vital for their survival. Yet, what actually determines whether an individual develops into a male or female varies ...
