Genetics Pierce 4e

Genetics Chpt 1 Introduction to genetics

Genome Complete set of genetic instructions for an organism
Transmission genetics Field of genetics that encompasses the basic principles of genetics and how traits are inherited
Molecular genetics Study of the chemical nature of genetic information and how it is encoded, replicated, and expressed.
Population genetics Study of the genetic composition of populations (groups of members of the same species) and how a population's collective group of genes changes with the passage of time
Model genetic organism An organism that is widely used in genetic studies because it has characteristics, such as short generation time and large numbers of progeny, that make it particularly useful for genetic analysis
Pangenesis Early concept of heredity proposing that particles carry genetic information from different parts of the body to the reproductive organs
Inheritance of acquired characteristics Early notion of inheritance proposing that acquired traits are passed to descendants
Preformationism Early concept of inheritance proposing that a miniature adult (homunculus) resides in either the egg or the sperm and increases in size in development, with all traits being inherited from the parent that contributes the homunculus
Blending inheritance Early concept of heredity proposing that offspring possess a mixture of the traits from both parents
Cell theory States that all life is composed of cells, that cells arise only from other cells, and that the cell is the fundamental unit of structure and function in living organisms
Germ-plasm theory States that cells in the reproductive organs carry a complete set of genetic information
