Start off with 2,500 plants of which 50 % have medium - tip leaves , 25 % have wide - tip leaves , and 25 % have drip - tip leaves . Each circle in your simulation will represent 125 organisms . Calculate how many circles you need for each trait , and then create your simulation . Be sure to include a key that states the color coding for each trait
