SI Wednesday, March 25, 2009 5:14 PM 1. H-W o Study real world conditions for theoretical absence o 5 conditions for H-W equilibrium No mutations ( no new forms of genes introduced) No natural selection (no selection for or against any specific traits) No sexual selection (Random mating) Isolated population ( no gene flow) Large population (prevents genetic drift. Chance of randomness affecting decreased) o If these are met gene pool will not change 2. Questions either given gene pool or population makeup 3. p = A 4. q = a 5. p and q are allelic frequency in total gene pool 6. .5P - dominant 7. .5Q - recessive 8. 1=p + q 9. 1=(p+q)(p+q) 10.1=p 2 +2pq+q 2 11.
