,Key Concepts
• Mendel used the scientific approach to identify two laws of
inheritance
• The laws of probability govern Mendelian inheritance
• Inheritance patterns are often more complex than
predicted by simple Mendelian genetics
• Many human traits follow Mendelian patterns of inheritance
,Overview: Drawing from the Deck of Genes
• What genetic principles account for passing of traits from
parents to offspring?
