blending inheritance
|
early concept of heredity proposing that offspring possess a mixture of 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 lving organisms
|
|
genome
|
complete set of genetic instructions for an organism
|
|
germ-plasm theory
|
states that cells in the reproductive organs carry a complete set of genetic information
|
|
inheritance of acquired characteristics
|
early notion of inheritance proposing that acquired traits are passed to descendants (not true)
|
|
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 well suited to genetic analysis
|
|
molecular genetics
|
study of the chemical nature of genetic information and how it is encoded, replicated, and expressed

|
pangenesis
|
early concept of heredity proposing that particles carry genetic information from different parts of teh body to the reproductive organs (not true)
|
|
population genetics
|
study of the genetic composition of populations and how a populations collective group of genes changes with the passage of time
|
|
preformationism
|
early concept of inheritance proposing that a miniature adult (homunculus) resides in either the egg or the sperm and increases in size during development, with all traits being inherited from the parent that contribures the hounculus (not true)
