Recent advances in molecular genetics have provided hundreds of thousands of single nucleotide polymorphisms to detect mutations at the vicinity of genes related with quantitative traits. Breeding values could be used as response variable in mixed model framework to detect possible associations with genomic relationship matrix. It is known that most of quantitative traits are correlated which leads to construct of networks and pathways of genes due to pleiotropy. Hence the main aim of this paper is to a) detecting pleiotropy by principal component analyses methods b) prediction of genomic breeding values by ridge regression c) detecting associations based on predicted genomic breeding values obtained from b) using QTLMAS 2010 simulated dataset. Most of the Quantitative Trait Locus (QTLs) were located at chromosome 1 and 3. Highest correlation between true breeding value and predicted breeding value were obtained by Gaussian Kernel function as 0.557. To detect pleiotropy we used first and second principal components as response variable and success rates found to be 0.2727 and 0.1714 and error rates found to be 0.5952 to 0.6400 for first two principal component loadings respectively. Using genomic breeding values as response variable gave better success rate and lower error rate compared with when using raw phenotypes. We found that using the most heritable and variable component (first component) had higher change to detect pleiotropic genes using QTLMAS-2010 dataset

Moleküler genetikteki son gelişmeler fenotipler ile ilişkili olabilen başkalaşımların: yüz binlerce tekil nükleotit polimorfizmi ile saptanmasına olanak tanımıştır. Damızlık değerlerin karışık modellerde cevap değişkeni olarak kullanılması ile genom tabanlı ilişkiler tespit edilebilir. Pleiotropi nedeni ile farklı fenotipler birbirleri ile bağıntılı olabilmekte ve böylece gen ağları oluşturulabilmektedir. Dolayısı ile bu çalışmanın amaçları a) pleiotropinin temel bileşenler analizi ile tespiti b) Ridge regresyonu kullanarak genomik damızlık değerlerin tahmini ve c) b)’den elde edilen damızlık değerler ile ilişki analizini benzeşim yolu ile elde edilmiş QTLMAS 2010 veri seti ile yapmaktır. Verimden sorumlu bölge (QTL)’lerin büyük çoğunluğu 1 ve 3. kromozomlarda bulundu. Gerçek ve tahmin edilen damızlık değerler arasındaki en yüksek korelasyon Gausçu çekirdek ile bulundu (0.557). Birinci ve ikinci temel bileşenler ile pleiotropi tespitinde başarı oranları 0.2717 ve 0.1714; hata oranları ise 0.5952 ve 0.6400 olarak bulundu. Genomik damızlık değerlerinin cevap değişkeni olarak kullanılması fenotiplerin kullanımına oranla daha yüksek başarı oranı ve daha düşük hata oranları verdi. Pleiotropik genlerin tespitinde kalıtım derecesi ve çeşitliliği en yüksek olan ilk temel bileşenin kullanılması QTLMAS 2010 veri seti için daha iyi sonuç vermiştir
