genetic explanation

• gene

  segment of dna that controls production of one protein
• influence of genes on behaviour is complex 


  unlikely that just one gene is responsible for only given behaviour
• influence of genes on behaviour is complex

  behaviour more likely caused by combination of lots of different genes
• influence of genes on behaviour is complex

  environmental factors have a bigger impact on behaviour than on physical traits
• according to the genetic explanation of ocd, there are multiple gene alleles that can contribute to developing ocd
• if a person has more of these gene alleles their chances of developing ocd increase
• we can inherit ocd from our parents
