If the elevation of the slope is correlated with fitness, then hybrids should perform consistently better than one parent but worse than the other in either parental environment.
Moreover, there is a dynamic equilibrium between genetic stability (the capacity of individuals to produce offspring adapted to the parental environment) and genetic variability (the capacity to produce offspring with requirements that are different from those of their parents).
Evidence is accumulating that the quality of the parental environment is associated with oxytocin biology in children.
The present study was designed to examine the interaction of the single nucleotide polymorphism (SNP) rs2254298 within the oxytocin receptor (OXTR) gene and quality of parental environment in predicting children's psychosocial functioning.
More specifically, in a sample of 92 Caucasian adolescent girls (9 14 years old), we examined whether adverse parental environment, operationalized as mothers' history of recurrent major depressive disorder, interacts with the rs2254298 SNP on the OXTR gene to predict daughters' symptoms of depression and anxiety.
Moreover, a host of events implying unstable parental environment and separation during childhood (encompassing, e.g, parental military service, job relocation, separation, divorce, death, etc).
In man, many different events implying childhood separation from caregivers/unstable parental environment are associated with heightened risk for panic disorder in adulthood.
We further hypothesized that such alterations in behavior, and the associated modifications in brain gene expression profiles, would be transmitted to the offspring, thereby suggestively prepare the offspring for the parental environment.
These genotypes only show significant differences in germination responses to the offspring environment when the parental environment was saline, but no such differences were seen when the parental environment was non-saline.
When athletes claim that they are not role models, it only reveals that they do not have the character or integrity, nor do they want the responsibility, to be examples for the American youth, who do not have strong parental environments and turn to our athletes for inspiration.
In Pinus pinaster, parental environmental effects on seed mass partially explained variation in germination timing between contrasting parental environments [ 33].
