Dear "The Cypriot"
Would you kindly remove this "eugenic"-style comment or modify accordingly:
Ethnicity? This is almost certainly wrong on genetic grounds. The frequent appeals to both communities for bone marrow donors show Cypriots share more genes with each other than with the populations of either Greece or Turkey. We look the same, for goodness sake!
Whilst how we look may be your honorable opinion (I disagree btw), the highlighted inference to genes is scientifically invalid. The essential DNA-homology studies needed to make such a deduction have not been carried out.
Generally, it would be simplistic (and dangerous) to make sweeping speculations from isolated genetic data; and in this case completely erroneous to jump to an ethnicity association based on tissue matches. Indeed it is often the case tissue matches cannot be found within one's immediate family. By the same logic would that mean one is not in the same ethnic group as one's biological mother or father?
Genetic data is open to such abuse and if you wish to avoid purveying misinformation you need to re-consider the wording of this conclusion. Removal altogether would be more appropriate.
[I can provide you with a fuller explanation of how phenotypes (manifested characteristics) and genotypes (DNA similarities) can mislead towards unfounded relatedness if you wish.]
