- For example: Specimens of the same variety of crop
- less obvious differences
- Animals of different species

- Genes
- Nucleus of all animal cells contain genes
- Genes are arranged in Chromosomes like beads on a necklace
- They are instructions which control the characteristics that develop in different individuals
- Effect of environmental differences
- Identical twins are formed with the same egg and sperm; therefore, their genetic information are exactly the same, but there are still obvious difference due to environmental and way of living factors.
- It has more of an effect on plants, due to differences in light, temperature, soil acidity or alkaline.
- Variation is caused by 3 factors
- Inherited Environment Combination of both
- Environment examples- Strength and weight
- Both examples- Personality and intelligence
- Inherited examples- Eye and hair colour
- Inherited Environment Combination of both
