Genetics - study of genes or all living systems

Genetics: This is the study of variations or inheritance including the study of genes. Genetics is a discipline of biology. It is the science of heredity, genes or variation in living organisms. Genetics deals with the molecular structure or function of genes, with gene behavior in the context of a cell or organism like dominance or epigenetic with patterns of inheritance from parent to offspring, or with gene variation, distribution or change in populations.

Genetics may also be applied to the study of all living systems, from viruses & bacteria, through plants especially crops or domestic animals, to humans as in medical genetics. The modern science of genetics, that seeks to understand the process of inheritance, only began with the work of Gregor Mendel in the mid-19th century. Genes correspond to regions within DNA, a molecule includes a chain of four different kinds of nucleotides-the sequence of these nucleotides is the genetic information organisms inherit. Each strand of DNA can act as a template for creating a new partner strand. This is called the physical method for making copies of genes which can be inherited.
