You have been assigned the job of maintaining one population of horses exactly like they are (same genetic variety and characteristics) far into the future, while promoting genetic change in a second group. Using the two islands, drag the conditions for each of the groups onto the island in order to either promote change (evolution) or stifle it.
Miles of ocean discourage Evolving Population
Stable Population horses from attempting to swim towards the mainland.
Dominant stallions prevent other stallions from mating.
Mutations occur, but over generations these mutations do not persist.
Small population size Large population size A few horses are able to swim across the channel to join mainland herds
The gametes of the mares tend to suffer from mutation caused by certain plants on the island.
Reset Stallions and mares show no preference in mate choice.
