  9. Nonrandom mating & sexual selection

  10. How to measure allele frequency

  11. Hardy Weinberg Equilibrium • 1. no mutations • 2. No natural selection • 3. No gene flow • 4. large population size • 5. random mating

  12. Hardy Weinberg equations • p= • q= • p2= • q2= • 2pq=

  14. Practice Hardy Weinberg • Population of 100 cats. 84 black (B) , 16 white (b). How many of each genotype?

  15. Natural Selection – Stabilizing

  16. Natural Selection- Directional

  17. Natural Selection- Disruptive

  18. Activity to show graphing
