6. Passing of traits from parent to offspring

7. Science of Heredity Branch of Biology that seeks to explain biological variation

8. Chance that a given event will occur Usually expressed as a fraction or a percent

9. Multiply 2 separate events together Probability of tossing 2 coins heads up –½–½ X ½ = ¼

10. The probability of an event that can occur in 2 or more different ways is the sum of the separate probabilities of those ways Probability of an F 2 heterozygote –¼–¼ + ¼ = ½ (2/4)
