Genetics is the study of genes, heredity, and genetic variation in living organisms. It involves the analysis of DNA and how it codes for traits that are passed down from one generation to the next.
Geneticists study inheritance patterns, genetic mutations, and how genes interact with each other and with the environment to produce observable traits in organisms. They use a range of techniques, including DNA sequencing and genome editing, to investigate genetic processes and their impacts on organisms.
Genetics has important practical applications in medicine, agriculture, and biotechnology. It has helped in the development of gene therapies, genetically modified crops, and genetically engineered organisms for industrial and medical purposes.
