Draw conclusions: Each time you bred the parent chickens, you completed a trial. A trial is a single time that you conduct an experiment. Random chance often causes identical trials to have different outcomes. Because of this, scientists repeat experiments many times in order to make sure that chance alone is not responsible for the results of a trial.
How did your results change as the number of trials you completed increased? Why was it important for you to breed the chickens repeatedly in this experiment?
