  1. What is inheritance?

  2. The Royal Family

  3. Inherited Characteristic or Not?

  4. Inheritance Many characteristics of living things are determined by genes inherited from our parents. But a gene can have different forms; these are called alleles. https://www.glowscience.org.uk/mindmap/#!/biology/cells_and_dna/genetics

  5. Alleles Different forms of the same gene…

  6. Chromosomes: chromosomes are large pieces of DNA. Humans have 23 pairs of chromosomes in most cells. Genes: genes are sections of chromosomes, each codes for a different characteristic e.g. blood type, eye colour, etc. Alleles: different forms of the same gene

  7. Phenotype This is what an organism looks like… Green eyes Brown hair Short height Lobbed ears

  8. Genotype This is the forms of a gene an organism carries in its DNA Dad: BlueEyes Mum: GreenEyes Me: Green eyes Phenotype: Green Eyes Genotype: I carry a green and blue eyed gene
