What are Genetics?

According to the Hutchinson Abridged Encyclopedia, genetics is the branch of biology concerned with the study of heredity and variation in organisms. It aims to explain how characteristics of living organisms are passed on from one generation to the next. The science of genetics is based on the work of Austrian biologist Gregor Mendel, whose experiments with the cross-breeding (hybridization) of peas showed that the inheritance of characteristics and traits takes place by means of discrete ‘particles’, now known as genes. These are present in the cells of all organisms and are the basic units of heredity. All organisms possess genotypes (sets of variable genes) and phenotypes (characteristics produced by certain genes). Modern geneticists investigate the structure, function, and transmission of genes. Since the 1990s, this has been complemented by the large-scale study of entire genomes, a branch of genetics known as genomics.
