Two groups of flies live in the same area. One group has a mutation that causes them to prefer the dark, so this group is awake and active at night, while the other group is awake and active during the day. As a result, they never interbreed.
A type of bird bases mating choices on elaborate dances by the male. A mutation causes some males to be unable to dance, but a small group of females prefer this, so they become a separate group.
A large warehouse is built in the middle of a field, separating two groups of click beetles.
A donkey and zebra can produce a zonkey, but a zonkey cannot have babies.
Long-stemmed roses and beach roses can produce fertilized seeds and grow new plants, but the plants have weak root systems and die before they are fully grown.
A common coqui frog and a whistling coqui mate and produce eggs, but the embryos never develop and the eggs never hatch.
