  • Chromosomes are the genetic information within a cell. 
  • The chromosomes are composed of a molecules called DNA (DeoxyriboNucleic Acid).
  • Section of the chromosomes are called genes. 1 chromosones will have many genes.
  • Each genes carry the information for the construction of protein.
  • protein gives us characteristic association with the gene eg blood.
  • Different organism have different amount of chromosomes                                                                                                                 
  • Chromosomes operates in pairs = Homologous pairs.

The gene loci = same gene

characteristic has 2 version of each gene = called Alleles
