Genetik faktörlerin şiddet davranışı üzerine etkisi

Davranış genetiği, davranış kalıpları ve kişilik özelliklerine genetik ve çevresel faktörlerin etkisini inceleyen bilim alanıdır. İnsan genomunun dizilenmesiyle birlikte, davranış ve kişilik özelliklerinin gelişiminde genlerin etkisini araştıran çalışmalar hız kazanmıştır. Kompleks davranış ve özelliklerin, çoklu gen tarafından düzenlendiği görülmüştür. Yapılan araştırmalar göstermiştir ki, bireyler arasındaki davranışsal farklılıkları açıklamak için sadece genlerin incelenmesi yeterli değildir. Aynı zamanda genlerin işlevini etkileyen çevresel faktörlerin de dikkate alınması gerekmektedir. Deneyimler, genlerin ifade edilme özelliklerini değiştirerek bir ömür boyu insan genomu üzerinde ve sonraki kuşaklarda epigenetik işaretler bırakır ve kişiye özgü davranış kalıplarının oluşumunu sağlar. Bu derlemede gen ve çevrenin davranışlarımız üzerine olan etkisi ele alınmış; çağımızın önemli sorunlarından olan antisosyal davranışlar ve şiddetin genetik yönü tartışılmıştır.

The Effect Of Genetics Factors On Agressive Behavior

Behavioral genetics examines the role of genetic and environmental factors on the behavior patterns and personality traits. With the sequencing of the human genome, studies have focused that which genes are active in the development of behavior and personality traits. The complex behavior and properties are regulated by multiple genes. Studies have shown that to explain the behavioral differences between individuals not only genes but also environmental factors that affect the function of the gene must be considered together. Experience of a lifetime by changing the expression of genes leave epigenetic marks on the human genome and allows the formation of the individualized behavior patterns. In this article, gene-environment interactions on behaviour was handled, and the antisocial behavior and violence as important issues of our age which their genetics were discussed.
