Genetic factors and shared environment contribute equally to objective singing ability.

ABSTRACT: Singing ability is a complex human skill influenced by genetic and environmental factors, the relative contributions of which remain unknown. Currently, genetically informative studies using objective measures of singing ability across a range of tasks are limited. We administered a validated online singing tool to measure performance across three everyday singing tasks in Australian twins (n = 1189) to explore the relative genetic and environmental influences on singing ability. We derived a reproducible phenotypic index for singing ability across five performance measures of pitch and interval accuracy. Using this index we found moderate heritability of singing ability (h ² = 40.7%) with a striking, similar contribution from shared environmental factors (c ²
