2. Sex-linked traits Genes that are carried on the X chromosomes
Examples:
Hemophilia
Baldness
Red-green color blindness

6. Genetic Engineering
Changing one or more genes in the DNA of an organisms
Genetically Modified Food
Genetically Modified Pests
Genetically Modified Animals
Genetically Modified Humans?

7. The Process: Gene Replacement
1. The original gene is cut out of the organism that will be modified
2. An engineered gene is added in place of the cut out gene

8. The Process: Cloning
Cloning is used when an identical copy of a cell or organism is desired
Can be used to create an entire new individual
Can be used to create specific cells in disease treatment

9. GMOs = Genetically Modified Organisms
Why – Allows for specific traits in organisms
Examples –
Crops with higher crop yield (bigger, more fruit, vegatables)
Pest Resistance
Increased temperature tolerances

10. Bioluminescent Animals
Uses:
Protein tracking
Disease detection using bioluminescent imaging (BLI) to identify different types of cells
Novelty pets (Glofish are available now)

11. Fast-Growing Salmon Less Smelly Cows
Genes from two other fish cause this salmon to continually produce growth hormones
Less Smelly Cows
Modifying bacteria responsible for methane production in cattle results in 25% less-flatulent cows
