Mirror image! Identical twin sisters, 4, do everything in exactly the opposite way to each other - from parting their hair to holding a pen

  • Leah and Erin Sullivan, 4, are like 'two sides of the same coin' according to mum
  • They do everything the exact opposite - from parting their hair to holding pens
  • Mother Zoe, 42, said the pair are completely opposite in personalities too
  • It is known as 'mirror image twins' and affects up to a quarter of identical twins Four-year-old 'mirror image' twins do everything from parting their hair to holding a pen in precisely opposite ways. 

    Leah and Erin Sullivan, from Inverness, Scotland, are like 'two sides of the same coin' according to their mother Zoe, 42. 

    While Leah parts her hair on the left, Erin parts hers on the right and both favour opposite hands for throwing or writing.

    The pair even sleep in exactly the same position, but on different sides.

    They are 'mirror-image twins' - a little-known phenomenon that means otherwise identical siblings are asymmetrical in their looks and how they move or interactThe phenomenon is believed to affect up to a quarter of identical twins, and Zoe found out her twins were affected last year. 

    Stay-at-home mother Zoe said: 'If their hair has been up, it's really hard to tell them apart!

    'Leah's hair grew faster, but it wasn't until they were both about two and a half that their fringes started to grow out and I realised it parted on different sides! 

    'It didn't matter what you did, like trying to part it in the middle or on the other side, and really it's the only way you can tell them apart! 

    'That is when we realised they were mirror twins. Erin we think could be left-handed but Leah is definitely right-handed. 

    'After I noticed it I did look it up on the internet, it can be really extreme!'

    She said Leah usually stands on the left in photos, with Erin on the right, and they walk with opposite dominant feet. 

    And when they face each other it looks exactly like they are looking in the mirror. 

    Their nursery also uses their unique hairstyles to tell the difference, but there could yet be more symmetries that reveal themselves as the girls grow older. 

    Zoe added: 'They are totally different in personality. Almost like different sides of the same coin. 

    'Every bit of personality Leah has, Erin doesn't, and vice versa.

    What are 'mirror image twins'? 

    'Mirror image twins' is a phenomena which occurs in approximately 25 per cent of all identical twins. 

    The term is used to describe twins who are matched as if they're looking into a mirror, with defining characteristics like birthmarks, dominant hands, or other features on opposite sides. 

    It is unclear what causes the mirroring in some twins, although some researchers suggest the phenomenon occurs when an egg splits later in the fertilisation process. 

    Identical twins are the result of a single fertilised egg splitting into two embryos between four and eight days post-conception.

    It is thought that mirror twins are the result of the egg splitting even later, between nine and 12 days, although this has never been proven. 

    Mirror twins can only occur when a single egg splits, and therefore all mirror twins are identical, but not all identical twins are mirror twins. 

    They usually have opposite anatomical features, such as a freckle on the left cheek while the other has one on the right, but they typically have identical eye and hair colours. 

    The condition is self-identified and there is no specific test used to diagnose mirror twins. 

    A DNA test can confirm whether twins are identical but there are no markers related to the mirror phenomenon. 

    Some examples of mirrored features include: birthmarks, freckles, moles, dimples, ear shape, eye shape, nose shape, hairline, teeth. 

    They may also have asymmetrical physiological features, with some sleeping on opposite sides. 

    Others have altered gaits, including one leading with their right hand and the other with their left, or one being left-handed and the other right.
