Genomic studies

Genomic studies (genomics) is the study of the whole genome of an organism. Using bioinformatics and high-performance computing, genomic researchers examined massive amounts of deoxyribonucleic acid (DNA)-sequence data to discover variations or mutations that affect drug response, health, or disease. Genomics is a much younger discipline than genetics, having only emerged in the last few decades as a result of technological advancements in DNA sequencing and computational biology.

Question

Definition Definition Observable physical traits or characteristics of an organism, which are determined by its genetic makeup (genotype) as well as environmental factors. These traits can include anything from eye color or height to behavior or disease susceptibility. Understanding an organism's phenotype is important in fields such as genetics, medicine, and ecology.
