- "Furthermore, we found that the intra-pair correlations of the two parenting dimensions—warmth-reasoning and harshness-hostility—were also greater in MZ twins than in DZ twins, indicating genetic influences on parenting. This result is consistent with prior findings on genetic etiology of parenting (Klahr & Burt, 2014; Neiderhiser et al., 2004 Neiderhiser et al., , 2007), supporting the rGEs (Jaffee & Price, 2012 ). Moreover, we found that the cross-twin-cross-trait correlations (i.e., Twin 1's parenting with Twin 2' anxiety) in MZ-twin pairs were also larger than those in DZ-twin pairs, indicating that the associations between parenting and anxiety may be partially explained by common genes.

[Show abstract] [Hide abstract] ABSTRACT: The associations between parenting practices and adolescent anxiety symptoms were examined in both individual and monozygotic (MZ) twin differences levels. Participants were 804 pairs of Chinese MZ adolescent twins aged 10–18 years (M = 13.57, SD = 2.67, 52% females). Twins’ anxiety symptoms were assessed by self- and parent-reports. Twins also reported their perceived parenting practices. On the individual level, parental warmth-reasoning was negatively, whereas harshness-hostility was positively, associated with both self- and parent-reported youth anxiety. On the MZ-twin differences level, the magnitudes of the associations between parenting practices and youth anxiety were decreased. MZ-twin difference in parental warmth-reasoning remained significantly associated with self- and parent-reported youth anxiety; MZ-twin difference in parental harsh-hostility was only significantly associated with self-reported youth anxiety. This study indicated that parental warmth-reasoning and harshness-hostility may be unique environmental experiences that influence youth anxiety, and illustrated the necessity of controlling for gene-environment correlations when examining the true environmental effects of parenting on child behavior. -
- "Their caregivers may in turn withdraw, resulting in less parental knowledge (Dishion, Nelson, & Bullock, 2004; Kerr & Stattin, 2003; Kerr, Statin, & Pakalniskiene, 2008). This is an example of an evocative gene–environment effect, such that individuals with particular genotypes evoke particular responses from their environments (Klahr & Burt, 2014; Plomin, DeFries, & Loehlin, 1977). Therefore, differences in parental knowledge may be partially determined by genetic differences between individuals (Plomin, Reiss, Hetherington, & Howe, 1994; Reiss, Neiderhiser, Hetherington, & Plomin, 2000).

Article: Parent and peer influences on emerging adult substance use disorder: A genetically informed study
[Show abstract] [Hide abstract] ABSTRACT: The present study utilizes longitudinal data from a high-risk community sample to examine the unique effects of genetic risk, parental knowledge about the daily activities of adolescents, and peer substance use on emerging adult substance use disorders (SUDs). These effects are examined over and above a polygenic risk score. In addition, this polygenic risk score is used to examine gene-environment correlation and interaction. The results show that during older adolescence, higher adolescent genetic risk for SUDs predicts less parental knowledge, but this relation is nonsignificant in younger adolescence. Parental knowledge (using mother report) mediates the effects of parental alcohol use disorder (AUD) and adolescent genetic risk on risk for SUD, and peer substance use mediates the effect of parent AUD on offspring SUD. Finally, there are significant gene-environment interactions such that, for those at the highest levels of genetic risk, less parental knowledge and more peer substance use confers greater risk for SUDs. However, for those at medium and low genetic risk, these effects are attenuated. These findings suggest that the evocative effects of adolescent genetic risk on parenting increase with age across adolescence. They also suggest that some of the most important environmental risk factors for SUDs exert effects that vary across level of genetic propensity. -
- "Kendler and Baker (2007) conducted a review of 55 independent genetic studies and found an average heritability of 0.27 across 35 diverse environmental measures (confidence intervals not available). Meta-analyses of parenting, the most frequently studied domain, have shown genetic influence that is driven by child characteristics (Avinun & Knafo, 2014 ) as well as by parent characteristics (Klahr & Burt, 2014). Some exceptions have emerged. "
