Biotechnology

Organisms that is homozygous for desirable traits.

Purebred

Type of breeding in which genetically distant organisms. F Type of breeding in which genetically distant organisms F. Selective breeding are crossed.

Outbreeding

Effect exhibited by an organism that is larger or healthier Effect exhibited by an organism that is larger or healthier due to the breeding of distantly related parents.

Hybrid Vigor

Type of breeding in which organism of similar genotype are crossed to maintain a desirable set of traits

Inbreeding

Breeding organisms to produce certain desirable traits.

Selective Breeding

For the following problems what is the disease for the genetically engineered treatment.

Healthy genes combined with viruses or carrier cells to replace abnormal genes that cause excess mucus secretion.

Cystic Fibrosis

Protein under development that causes blood to clot.

hemophilia

Protein that binds to specific types of cells to carry radioactive tracers or medicine to abnormal cells.

Cancer

Final Question

Human gene is inserted into bacteria, which then produce a human hormone.

Diabetes

Genetically engineered bacteria to dissolve blood clots

Heart Disease
