Male pattern baldness is inherited: you get it from your ancestors. Now scientists have found the method that it gets transmitted from generation to generation: it's in your DNA.
Researchers conducted a genome-wide association study of 1,125 Caucasian men who had been assessed for male pattern baldness. They found two previously unknown genetic variants on chromosome 20 that substantially increased the risk of male pattern baldness. They then confirmed these findings in an additional 1,650 Caucasian men.
