Genetics

Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

History of Genetics

Genomics involves the study of genes, genetics, inheritance, molecular biology, biochemistry, biological statistics and incorporates the knowledge of advanced technology, computer science and mathematics.
