1) Select an organism which consists of a population having two distinct traits. You can be creative here (red and green beetles, humans with red hair and brown hair, birds with short beaks and long beaks and so on). Alter that percentage (you decide how drastically). State new percentages?

2) Select one of the following for shift in trait percentages for your “population”.

a) Random genetic drift.

b)Gene flow.

c) Non-random mating.
