These needs and worries vary in degree, develop in childhood and probably have a temperamental and a genetic component, said Arie Kruglanski of the University of Maryland.
"To learn they have a disease with a genetic component like other diseases really helps them understand these crazy sort of behaviors".
ANOVA indicated that 58.6% of the variance is between genotypes [approximately equal to the broad sense heritability (Falconer 1981, p. 115)], indicating a large genetic component.
Although the ANOVA calculation used here measures heritability in a broad, rather than gene-specific, manner, the results suggest that TST and OF behaviors have a strong genetic component.
That said, "There is certainly a genetic component, a gift involved," Squire acknowledges.
It has a genetic component, so a family history increases the risk even more.
Mental illness has a strong genetic component.
There's also a large genetic component in there.
Twin studies also argue for a large genetic component.
A. Not necessarily, though there is a strong genetic component in allergy.
