Abstract

Homozigotluğun artmasına neden olarak doğumsal bazı hastalıkların görülme
riskini artıran soy içi evlilik ülkemizde oldukça yaygındır. Bu çalışmada iç evliliğin genç
erkeklerin gelişim kalitesi üzerinde yarattığı etkiler incelenmeye çalışılmıştır. Bu amaçla
Ankara’da yaşayan ve ebeveynleri 1. dereceden kuzen olan (F = 0,125) 144 erkek lise
son sınıf öğrencisi ile aynı okullarda okuyan, benzer sosyoekonomik düzeyde yer alan ve
ebeveynleri arasında herhangi bir akrabalık ilişkisi olmayan (F = 0) 146 erkek
incelenmiştir. Bireylerden ağırlık ve boy ölçüleri alınmış ve beden kitle indeksleri (BKİ)
hesaplanmıştır. Gelişimsel kararlılık düzeylerini belirlemek için 8 antropometrik
bilateral değişken ölçülmüştür. Elde edilen bulgulara göre, ağırlık ve boy açısından iç
evli grup daha düşük değerlere sahiptir. İncelenen bilateral değişkenlerden hesaplanan
bileşik asimetri değeri, iç evli grubun daha fazla asimetrik olduğunu ortaya koymaktadır.
Sonuç olarak, akraba evliliğinin boy ve ağırlık gelişimi üzerinde olumsuz etki
oluşturulduğu, gelişimsel kararlılık üzerindeki olumsuz etkisinin ise anlamlı düzeyde
olduğu söylenebilir.
