- recessive allele
- Can be shown using family trees
- Inserting normal gene into
affected tissue
- Difficulties
- Gene must be expressed
- (Switched ON)
- Targeting appropriate cells
- NOT A CURE
- Potential to be effective treatment
- Natural Selection
- Charles Darwin
- Variation in species
- Best characteristics are
most likely to survive
- Genes are then passed on to next generation
- Over time the genes that gave an advantage
become most common in a species
- Evolution
