印刻效应(Imprinting Effect) 刚破壳而出的小鹅,会本能的跟随在它第一眼见到的母亲后面,即使不是它的母亲,而是一只猫、一只狗或一个玩具。只要它形成跟随反应后,不再对其他物体产生跟随。小鹅只承认第一,无...

Interestingly, the fact that an imprinting effect occured in one sex only is not necessarily due to the overall inactivity of the locus in the other sex (i.e. no detectable additive or dominance effect). Rather, at four loci that do not show an imprinting effect in males, we found a si...

Our results confirm the existence of significant differences in brain morphology between girls with TS and controls, and reveal the presence of a putative imprinting effect among the TS groups: girls with X(p) demonstrated thicker cortex than those with X(m) in the temporal regions bilaterally, ...
At several loci, no significant imprinting effect in either sex was found for some or all traits despite the fact that the locus shows a significant interaction effect (i.e., a significant difference between the sexes in the imprinting effect; see Additional file 2). In these cases, the ...
Studies have also shown that the effect on mate choice is not limited to the parent-child relationship in childhood; there is evidence that attachment at 15 months does not predict imprinting at 9 years of age, and that the influence of parental relationships in late adolescence persists (...
