Platy turned into swordtail?

I have a freshwater tropical tank with a mix of species. I originally purchased 4 platys, 1 male and 3 females. They started reproducing a while after, recently one of the fry has grown and now he resembles a swordtail! Is this just birth "defect" or is there something in the genetics in the past which caused this? Thanks!

    No. Swordtails and platies can interbreed, so this is prefectly normal.

    Cheers!
