Quick, think of your favourite pair of fictional twins. Got them? Now, be honest: Are they identical
If you answered "yes," there's a reason for that. Identical twins show up far more frequently in fiction than fraternal (non-identical) twins. If you don't believe us, take a Wiki Walk
through Twin Tropes
. We'll wait.
So why are twins always identical? Well, for starters, identical twins are visually striking. They allow for comic plots
, and they add symmetry and symbolism to a story. Fraternal twins, for all intents and purposes, are just regular siblings, and regular doesn't cut it in fictionland
This trope is so pervasive that it even manifests when the twins are different genders
-- Half-Identical Twins
shouldn't even be
Although there are sometimes aversions, the main subversion
of this trope is Non-Identical Twins
, when twins are said to be
identical but are obviously not.
In reality, fraternal twins are significantly more common than identical twins-- only 8% of twin births are identical.
