Describe Genes as being made of DNA molecules.
Understand that each gene has a different sequence of bases.
State genes are found on the Chromosomes in the nucleus of the cells.
Understand that genetic variation is a result of the differences in the genes of organisms
State that genes are inherited from parents.
Explain that during sexual reproduction there is mixing of the genes to produce new combinations.
