Term
selective breeding
Definition
the process by which desired traits of certain plants and animals are selected passed on to their future generations
Term
inbreeding
Definition
process by which two closely related organisms are bred to have desired traits and eliminate undesired ones in future generations
Term
test cross
Definition
involves breeding an organism that has the unknown genotype with one that is homozygous recessive for the desired trait
Term
genetic engineering
Definition
technology that involves manipulating the DNA of one organism in order to insert exogenous DNA
Term
genome
Definition
a organism's total DNA present in the nucleus of each cell
Term
restriction enzymes
Definition
proteins that recognize and bind to specific DNA sequences and cut into fragments
Term
gel electrophoresis
Definition
a process by which an electric current used to separate DNA fragments according the size of the fragment
Term
DNA fingerprinting
Definition
involves separating these DNA fragments using gel electrophoresis in order to observe the distinct banding patterns that are unique to every individual
