• DNA is stored as chromosomes that contains genes
• sequence of bases determine nutrient that is produced
• alleles are different versions of the same gene
• genes that are inherited determine characteristics
• some characteristics are controlled by one single gene
• there are two versions of every gene in body
• Genotype : combination of alleles you have
• Phenotype: how will look due to different of alleles
