Same Sex Triplets

With twins, you might get a boy and a girl. But triplets are almost always the same sex. That's what the media wants people to think. Usually, they will be all identical, but sometimes, they are all fraternal for easy recognition. In Real Life, identical triplets are always all boys or all girls (for obvious reasons), but most triplets are two identical and one fraternal and only have a fifty-fifty chance of all being the same sex. All-fraternal triplets only have a one-in-four chance.

So why are Same Sex Triplets so common in fiction? Because of Cast Calculus. Having one of each sex gives you balance, but three people don't divide evenly that way. So triplets are portrayed as three of a kind to give a sense of wholeness to the group. The same appeal makes Real Life Same Sex Triplets more marketable, so they are more likely to achieve fame as a group than mixed triplets. And if they happen to be children, Same Sex Triplets are just plain cute.

Compare Power Trio and Rule of Three. Many Twin Tropes also apply to triplets. If this trope is averted, they may be Three Amigos or Two Guys and a Girl.

Examples of Same Sex Triplets include:

Anime and Manga

Mitsuba, Futaba and Hitoha from Mitsudomoe.
The Ran triplets from Saiunkoku Monogatari, all of whom are named Setsuna. They also have personal names, but almost nobody uses them: multiple births are considered unlucky in Saiunkoku, so the triplets were raised to be as identical as possible and only the wife of one of the triplets and, eventually, Shuuei can tell them apart.

October, November and December from Coyote Ragtime Show.
The Hanamura Triplets from Sally the Witch.
