Q

Method to solve H-W problems

A

1) Make a column-row chart of data2) with data given add up all individuals/percentages 3) find p with data given ( x (AA) + 1/2 x (Aa) / 100% or total individuals )4) 1- p = q5) with given p and q solve for HW values (p^2, 2pq, q^2) and convert to %6) if #s have changed then no equilibrium*if given individuals, multiply the resulting HW values by the total # of individuals)
