Fig. 1From: Beads and Dice in a Genetic Drift ExerciseGeneral arrangement pattern for competing pairs. The difference in competitive skills increases the chances but do not determine the survival of the black variant. In the no selection model (simulation A), there is no selective pressure because each of the variants has a 50% chance of winning the competition event. The associated survival probabilities for weak and strong selection simulation patterns are also depicted (simulations B and C)Back to article page
