It is common knowledge that Incest or Inbreeding is widely practiced in albanian culture. This is done usually because of Isolation, cultural & religious reasons and to keep property within the family. The evidence is obvious and overwhelming. Some examples are: *Repetition of the same pair of surnames in marriages. *Increases numbers of disabled offspring. *Lower life span. *Jaw deformity *Intellectual & emotional problems Inbreeding can increase the chances of offspring being affected by recessive or deleterious traits. This generally leads to a decreased fitness and limits genetic diversity of a population, which is called inbreeding depression. For example, albanians! This is one of the reasons why albanians have far more genetic defects than any other race in Europe.
