| SELECTIVE BREEDING | Process of selecting a few organisms with desired traits to serve as parents of the next generation |
| INBREEDING | A selective breeding method in which two individuals with identical or similar sets of alleles are crossed |
| HYBRIDIZATION | A selective breeding 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 disorder |
| GENOME | All the DNA in one cell of an organism |
| MULTIPLE ALLELES | Three or more forms of a gene that code for a single trait |
| SEX-LINKED GENE | A gene that is carried on the X or Y chromosome |
| CARRIER | A person who has one recessive allele for a trait and one dominant allele, but does not have the trait |
| PEDIGREE | A chart or “family tree” that tracts which members of a family have a particular trait |
