What is genetic engineering
Genetic engineering is a technique where a gene can bee talen from one organism and placed into another to give a desired effect
Advantages of genetic engineering
Organisms can have mutations over others
Improved growth rate in plants & animals
Disadvantages of genetic engineering
Concerne of genetic mutation spread into food
Concerns of religious/anti meat
People may use genetic engineering to make their children taller, blue eyes etc
Variation of animals (Natural Selection)
There is always variation in a population because of the range of different genes
Competition of animals in Natural Selection
Individuals (animals) in a population compete for:
- Mates
- Shelter
- Food
Survival of the fittest of animals in natural selection
Individuals (animals) withthe best genes/characteristics are more likely to survive and be repodcued with
Inheritence of animals in natural selection
Successful individuals (animals) are likely to pass their genes on
Thereare 2 causes of variation
- What we inherit (genes)
