Słuch absolutny -- poszukiwanie podłoża genetycznego.

Absolute pitch is an ability to recognize and correctly name the pitch without external reference. The studies on absolute pitch incidence in families have shown familial association indicating further on significance of genetics factor connected with non-Mendelian inheritance. The finding was derived from population and molecular studies. The latter studies indicated for chromosome region 8q24.21 and for to a lower extent on 7q22.3, 8q21.11 and 9p21.3. Absolute pitch incidence depends on ethnicity and as such is more frequent in Far East Asia then in Western World. Then a frequency of absolute pitch declines with an age. Early musical training appears to consolidate absolute pitch in further life. Altogether, absolute pitch seems to be dependent both an genetic and environment factors. [ABSTRACT FROM AUTHOR]
