... pakistan is like brother of iran. apart from afghanistan (not hazara but tajik persians in afghanistan) pakistan is nr.2 in genetical identity to iran.
when combined the masses of both population of iran and pakistan you can see they are both similar, perhaps iranians are maybe 1,2 degrees lighter.
however you can always tell iranians by the colour and shape of their hair, eyebrow and skin tone, imo iranians are unique in this case.
modernday pakistan and afghanistan have been part of persian empire and other iranian empires that followed so no wonder people in that region look similar to each other.
