Heredity and Genetics

• Traits are characteristics that are inherited from parents
• These traits are controlled by genes, small pieces of DNA found in the chromosomes in your body.
• Through the process of meiosis, you inherited 23 chromosomes from your mother and 23 from your father.

HEredity

• Unless you have an identical twin, no one else has the same combination of chromosomes and genes you have.
• Your chromosomes contain DNA (deoxyribonucleic acid), the chemical code that tells your cells what to do.
