In a simple ecosystem that consists of rabbits and grass. The grass reproduces at a certain rate, and the rabbits randomly wander around the world eating the grass. If a rabbit stumbles across a patch of grass, they will eat it and gain energy. If a rabbit gains enough energy, they will reproduce. Conversely, if a rabbit wanders around too long without finding any grass to eat, they will die.

-Continuous inbreeding reduces productivity and fertility of the animals
-Inbreeding increases homozygosity
-Inbreeding to an ancestor increases the risk of inheriting any undesirable characteristics it carried.
