Discusses regulation of genetic expression, and mutation.
· How genes are controlled or 'regulated'.
· Cloning versus sexual reproduction.
· Changes to the DNA - good and bad.
· If all cells in an organism share the same genome, why aren't they all alike?
· We look at examples of totipotency.
· Any random change to a gene is a mutation; good, bad and neutral mutations. Oscar, the blind dog is a case of a double recessive mutated gene.
· Sexual reproduction mixes genes.
