This opposite phenomenon has been called negative prey switching, or anti-apostatic selection when it refers to the choice between different morphs.

Sometimes these different morphs of a single fungus were formerly thought to be separate species.

There are over 40 different morphs of this species disbursed throughout the lake.

Apostatic selection has been used by authors looking at the differences between different genetic morphs.

Using the different morphs and characters effectively is the key to beating the game.

Do the different morphs (be they different colour, adult size, shell shape, etc.) show the same food preferences?

For this to have any meaning the different morphs must be familiar with the same range of potential prey.

As a result of its robust nature, Littorina littorea can be highly variable in phenotype with several different morphs present.

Despite this, most species produce different morphs: zooids with different functions.
