- chromosomes
- the nucleus of a cell contains chromosomes made of DNA
- each chromosome carries hundreds to thousands of genes
- different genes contain the code to make different proteins and so control the development of different characteristics
- in body cells the chromosomes are found in pairs with one chromosome coming from each parent
- different species have different numbers of pairs of chromosomes
- e.g. humans have 23 pairs dogs have 39 pairs
