Answer:
The branch of biology that deals with heredity, especially the mechanisms of hereditary transmission and the variation of inherited characteristics among similar or related organisms.
These characteristics are determined by the expression of the genes present in the DNA of an offspring's cells. In sexual reproduction, the genetic form can normally be inherited from either of the biological parents.
Study of genes using molecular biology and recombinant DNA technology.
Genetics is the science of heredity. Heredity means the passing down of traits from one generation to the next.
