Slide 8 - Diapositive

Chromosomes form pairs.
1 pair contains information for the same characteristics

Phenotype

  • Genes that are on do something in the cell.
  • Genes that are off do nothing (for that cell)
  • Depends on the type of cell and place in the body
Example:
 Stomach cell : genes for hair colour are off.
 Stomach cell : genes for production of acid are on
