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 major goal of modern crop breeding is to efficiently combine multiple desirable traits by "stacking" the favorable gene variants (alleles) that contribute to those traits in a single crop variety. However, current strategies ...

In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, but over time, the copying process degrades. After many cycles of making copies, the ends of the ...

Transposons, DNA sequences that can self-replicate and move (jump) throughout the genome, are widespread and can affect cell survival if left unchecked. Cells control these "jumping genes" by silencing them, but little was ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA code itself—can also be ...
