| Word | Definition |
|---|---|
| Inbreeding | mating between closely related individuals; ensures that offspring are homozygous for most traits, but also brings out harmful, recessive traits |
| Test Cross | mating of an individual of unknown genotypes with an individual if known genotype; can help determine the unknown genotype of the parent |
| Genetic Engineering | method of cutting DNA from one organism and inserting the DNA fragment into a host organism of the same or a different species |
| Recombinant DNA | DNA made by recombining fragments of DNA from different sources |
| Transgenic Organism | organisms that contain functional recombinant DNA from a different organism |
| Restriction Enzyme | DNA-cutting enzymes that can cut both strands of a DNA molecule at a specific nucleotide sequence |
| Vector | means by which DNA from another species can be carried into the host cell; may be biological or mechanical |
| Plasmid | small ring of DNA found in a bacterial cell that is used as a biological vector |
| Clone | genetically identical copies of an organism or gene |
| Human Genome | map of the approximately 80,000 genes on 46 human chromosomes that when mapped and sequenced, may provide information on the treatment or cure of genetic disorders |
| Linkage Map | genetic map that shows the location of genes on a chromosome |
| Gene Therapy | insertion of normal genes into human cells to correct genetic disorders |
