Inbreeding involves crossing two individuals that have identical or similar sets of alleles
Hybridization a selective bredding method in which two genetically different individuals are crossed
Clone an organism that is genetically identical to the organism from which it was produced
Genetic engineering the transfer of a gene from the DNA of one organism into another organism in order to produce an organism with desired traits
Gene therapy the insertion of working copies of a gene into the cells of a person with a genetic disorder in an attempt to correct the disodrer
Genome is all the DNA in one cell of an organim
What are three methods for developing organisms with desirable traits? selective breeding, cloning, and genetic engineering
