Key Stage 2
Meaning
Inheritance is the features we get from our parents.
About Inheritance
- Living creatures inherit the features of their parents.
- When there are two parents the offspring will inherit some features of both parents.
Examples

 |
| If both parents have blue eyes the their children will all inherit blue eyes. | A spotted dog inherited those spots form its parents. | The shape of bird's beak is inherited form its parents. | Two parents with a "widow's peak" will have children with a "widow's peak". |
Key Stage 3
Meaning
Heredity is the passing down of traits from parent to offspring by DNA.
Key Stage 4
Meaning
Heredity is the genetic traits of an offspring passed down from its parents by DNA.
About Heredity
- The genome of an individual is inherited from its parents.
- In sexual reproduction half of the genome of an organism is inherited form each parent.
- Phenotypical traits of an organism will be the result of the [genotype]] containing pairs of recessive alleles or one or more dominant alleles.
- Some diseases are inherited from parents. These are known as inherited disorders.
