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.
