Hereditary information

Genotype

Phenotype

chromosomes & DNA

same chromosomes in every cell

Nuclei contain chromosomes: long thin treads, made of (mostly) DNA.

Gene: a piece of DNA containing the information (code!) for one hereditary trait.

(e.g. eye color, hair shape, blood type)

Genotype = Hereditary information in your DNA (genes).

• Is the same in all cells.
• Does not change.

Each body cell contains all the genes but not all genes are active

Genes can be switched on or off.

Example: Hair growth genes work in your skin but not in your eye ball.

Fenotype = All observable traits of an organism 

                       (how you look / appearance).

• Determined by genotype + environment.
• Can change.
