Lucy and Maria Aylmer are about as close as two twin sisters can get, but you’d never guess it just from looking at them – Lucy has fair skin and straight red hair while her sister has ebony, curly hair and dark skin. The twin girls, both from Gloucester, U.K., were born to a Caucasian father (Vince) and a half-Jamaican mother (Donna).

The unidentical twins also called dizygotic or fraternal twins, happen when two different eggs are fertilized by two different sperms at the same time. Meaning, that this type of twins is basically just regular siblings, that happened to be born at the same time, hence these two beautiful girls’ completely different looks.

No-one ever believes we are twins because I am white and Maria is black,,” Lucy said. “Even when we dress alike, we still don’t even look like sisters, let alone twins. When we’ve met friends for the first time, they never believe we are twins, and they have even made us produce our birth certificates to prove that we are actually twins.
