RESUMO
The pancreatic amylase (AMY2, E.C. 3.2.1.1) polymorphism has been studied in 2346 individuals from south-central and south-eastern Bulgaria. The allele frequencies have been determined as AMY2*1 = 0.9520 and AMY2*2 = 0.0480. The neighbor joining tree of seven subpopulations revealed only small genetic distances. Compared with other populations, the Bulgarian sample clustered with samples from Romania, Hungary, Germany and Switzerland, with larger distances to Albania, Greece and Macedonia.

Within a study of the genetics of Balkan populations, four DNA-STR systems and 19 classical markers were examined in seven samples: Romanians (two groups), Albanians, Greeks and Aromuns (three groups). The results for the DNA-STR systems have been compared with data from the literature. The results show four clear separated groups: sub-Saharan black populations, North-African, Japanese and European populations. The large Balkan populations, except the Greek sample, are genetically more homogenous than the Aromun populations. A second Neighbor-joining tree based on all 23 analyzed systems, show a particular trend of the Aromun groups, which indicates a particular genetic structure.

The allele frequencies of 12 STRs (D2S1338, D3S1358, D5S818, D8S1179, D16S539, D18S51, D19S433, D21S11, FGA, TH01, TPOX, VWA) from two Bulgarian population samples are presented: ethnic Bulgarians and Karakachani. The descent of Karakachani is not known. They are regarded as descendants of an older Balkan population, or that they may have nearer genetic relationships to the Aromuns. Using the allele frequencies of the 12 STR polymorphisms, the genetic relationships of Bulgarians and Karakachani to other Balkan populations have been studied. The results are compared with other population data, including two Aromun populations. While the Bulgarians show nearer relationships to other South Slavonian populations, there are no hints for nearer relationships between the Karakachani and other Balkan populations, especially the Aromuns. So, based on the 12 STRs, there is no indication for a closer relationship between Karakachani and Aromuns.

The distribution of 12 dermatoglyphic variables has been studied in 22 populations of Romania. The results of the neighbor joining tree analysis are discussed by means of geographical and historical relationships.

17 dermatoglyphic variables have been studied in five population samples from south-central and southeastern Bulgaria. The results have been combined with 10 hemogenetic markers. The neighbor joining tree analysis showed only small genetic distances between the samples. A comparison with data of the literature, using finger patterns and pattern intensity of fingers and considering the different results for males and females, revealed no clear geographical differentiation between most of the samples studied.

13 dermatoglyphic variables have been studied in eight population samples (five smaller isolated and three larger populations) to identify the possible differences between the larger and the smaller isolated populations. The data and neighbor joining trees for the dermatoglyphic variables show distinct differences between males and females. The isolated population of the Lutheran Mountains is clearly separated from the other populations. Combining the results of dermatoglyphic and 12 hemogenetic variables (only for six populations) the male and female trees are nearly identical. The three isolated populations are clearly separated, whereas the larger ones show smaller distances.
