In the present study, for estimating the Central Asia contribution to the Anatolia, nine Alu insertion polymorphisms (ACE, PV92, FXIIIB, APO, A25, B65, TPA25, D1, HS4.32 ) in 100 individuals from Anatolia were examined. Alu insertion frequency for these loci were calculated as 0,410; 0,220; 0,579; 0,963; 0,067; 0,667; 0,390; 0,427; and 0,637 respectively and they were found to be in Hardy-Weinberg equilibrium (p<0,05). Observed insertion frequencies of each loci were compared with those of the previous observations (Dinç, 2003; Comas et al., 2004) and it was found that the present study results were not different than those obtained by Comas et al. (2004). Thus, these two data were pooled (N = 143) and used to examine genetic relationships between populations from Eurasia and Africa. Pairwise Fst statistics indicated that there is higher genetic similarity between Anatolia and all of the Balkans and some of the Caucasian populations. Neighbor Joining (NJ) tree based on Reynold̕s genetic distances and Principal Component Analysis (PCA) both grouped the Anatolian populations with Balkans and some of the Caucasian populations and show clear differentiation of Asian populations from the Anatolian population. The relative genetic contribution of Central Asian genes to the current Anatolian gene pool was quantified using Admix analysis, considering for comparison populations of Balkans (Greek, Romania, Albania and Hungarian) and Central Asia (Uighur, Uzbeks, Tajicks, Kazaks, Kyrgyzes, Dungans). Estimates suggest roughly 28 % contribution from Asia to Anatolia in concordance with the previous estimation (Benedetto et al., 2001).

A novel approach for small sample size family-based association studies: sequential tests İlk Dağ, Özlem; Dungul, Dilay Ciglidag; ÖZDAĞ, Hilal; İLK, HAKKI GÖKHAN (Springer Science and Business Media LLC, 2011-08-01) In this paper, we propose a sequential probability ratio test (SPRT) to overcome the problem of limited samples in studies related to complex genetic diseases. The results of this novel approach are compared with the ones obtained from the traditional transmission disequilibrium test (TDT) on simulated data. Although TDT classifies single-nucleotide polymorphisms (SNPs) to only two groups (SNPs associated with the disease and the others), SPRT has the flexibility of assigning SNPs to a third group, that is,...
Morphometric, mtdna and microsatellite analysis in honeybee populations (apis mellifera L.) of north and northwest İran Farhoud, Houman Jabbari; Kence, Meral; Department of Biotechnology (2004) Morphometric measurements, mitochondrial DNA analyses and 5 microsatellite loci were used to investigate variation in the honeybee populations of Iran and comparing it with the Turkish populations. Five honeybee populations were sampled from North and west north of Iran. In morphometric aspect of the study 23 characters were measured from left forewings and hindlegs of honey bee samples. The data were analysed by multivariate statistical analyses. By using mtDNA analyses length polymorphism of the intergeni...
Morphometric and genetic differentiation between anatolia and Cyprus bonbus(bombus)terrestris (l.1758)populations Beton, Damla; Kence, Aykut; Department of Biology (2004) Four microsatellite loci were used to investigate differentiation in Bombus terrestris, a bumblebee of interest for its high value crops pollination. Two bumblebee populations, one from Ankara (the capital of Turkey) and one from North Cyprus were analyzed. In these populations, the total number of alleles detected per polymorphic locus ranged from 7 to 12. FST genetic distance between Ankara and North Cyprus B. terrestris populations based on four microsatellite loci was calculated as 0,09351. This applies...
Cloning and characterization of industrially important alpha-galactosidase genes from the human pathogen aspergillus fumigatus Söyler, U. Betül; Ögel, Zümrüt Begüm; Department of Food Engineering (2004) In this study, molecular cloning studies were performed on the a-galactosidase genes of Aspergillus fumigatus IMI 385708. This organism is an opportunistic saprophytic fungus and a human pathogen, mainly affecting immunocompromised patients. A. fumigatus is a thermotolerant fungus and can efficiently produce thermostable a-galactosidase. Two different cloning strategies were undertaken in this study. A. fumigatus cDNA library, prepared previously, was screened with three different probes. No net results wer...
Genetic diversity of native and crossbreed sheep breeds in Anatolia Koban, Evren; Togan, İnci Zehra; Department of Biology (2004) In this study the genetic diversity in Turkish native sheep breeds was investigated based on microsatellite DNA loci. In total, 423 samples from 11 native and crossbreed Turkish sheep breeds (Akkaraman, Morkaraman, Kivircik, Ivesi, Dagliç, Karayaka, Hemsin, Norduz, Kangal, Konya Merinosu, Türkgeldi) and one Iraqi breed (Hamdani) were analyzed by sampling from breeding farms and local breeders. After excluding close relatives by Kinship analysis, the genetic variation within breeds was estimated as gene dive...
