Evcil Koyun Verilerinde Tabii Seleksiyon ve Nötralitenin Test Edilmesi Üzerinde Bir Uygulama

Çeşitli coğrafi bölgelerde bulunan koyun populasyonlarında gözlenen kan grupları polimorfizime ilişkin birikmiş çok sayıda verileri kullanarak «Selektif Nötralite» ve dolayısıyla «Tabii Seleksiyon » hipotezlerinin test edilmesi konusu araştırılmıştır. Farklı coğrafi bölgelerde koyun populasyonlarının gösterdiği kan grupları ve biyokimyasal polirmorfizm verilerindeki varyasyon incelendiğinde, bu varyasyonun selektif nötralite hipotezinden kaynaklanmadığı görülmüştür. Söz konusu varyasyonun nedenleri tartışılmış ve incelenen kan grupları allellerinin hiç değilse hepsinin selektif nötral allel olmadığı, ancak az bir kısımının selektif nötral olabileceği sonucuna varılmışrtır.

An application of test of selection and neutrality in the data of domesticated sheep

The applicability of selective neutrality for sheep investigated due to accumulated data on it. The variations of gene :frequencies in sheep populations of World were discussed.The magnitude of genetic changes among populations were not consistent with selective neutrality hypothesis. The cause of exceptations of non selective neutrality for the data of world wide sheep polymorphisms were argued. It is concluded that not all alleles investigated were selectively neutral.
