It supports the claim that (D) the variability in neuroticism is due partly to genetic variability in the population
The amount of emotional stability that a person exhibits is indicated by their neuroticism. It is sometimes described as a negative personality feature characterized by unpleasant emotions, poor self-regulation (an inability to control desires), difficulty handling stress, a strong reaction to perceived dangers, and a propensity for complaining.
According to a meta-analysis of six twin cohorts with a total N of 29,496 and 29,501 twin pairs, respectively, the IRT-based scores for neuroticism and extraversion were heritable (48 and 49%, respectively), with a substantial portion of the heritability attributable to non-additive genetic variables.
These genetic variables qualitatively vary between sexes in extraversion. Any mega- or meta-analytic investigation that requires the harmonization of item-based behavioral measurements can use the item-response theory technique.

Question correction:
The estimated heritability of 48 percent for neuroticism in the population supports the claim that
A) the population in general has a recessive gene for neuroticism
B) the incidence of neuroticism is associated with that of another distinct trait
C) those with the neurotic trait share a particular dominant allele
D) the variability in neuroticism is due partly to genetic variability in the population
