Overview
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.
