Abstract Background and purpose: Paternal-fetal attachment behaviors areexpectantfather’s feelingtowards his unborn baby. These behaviors play very important roles in paternal identity, pregnancy outcome, and future growth and development of the baby. The severities of these behaviors are different between fathers and depend on many factors. The aim of this study was to assess paternal-fetal...
Maternal effects are now universally recognised as a form of nongenetic parental influence on offspring but, until recently, paternal effects were regarded as an anomaly. Although it is now clear that paternal effects are both widespread and important, their proximate basis and evolutionary consequences have received little attention and remain poorly understood. In particular, because many pat...

Recent studies have demonstrated that epigenetic changes resulting from malnutrition might play important roles in transgenerational links with metabolic diseases. Previously, we observed that exposure to a high-fat diet (HFD) in utero caused a metabolic syndrome-like phenomenon through epigenetic modifications of the adiponectin and leptin genes that persisted for multiple generations. Recent ...
Existing studies of the consequences of paternal incarceration for children treat paternal incarceration as a dichotomous event (a child either experiences paternal incarceration or does not), although effects could accumulate with both the frequency and duration of paternal incarcerations. In this article I use register data on Danish children from birth cohort 1991, some of whom experienced p...
Embryonic development requires a correct balancing of maternal and paternal genetic information. This balance is mediated by genomic imprinting, an epigenetic mechanism that leads to parent-of-origin-dependent gene expression. The parental conflict (or kinship) theory proposes that imprinting can evolve due to a conflict between maternal and paternal alleles over resource allocation during seed...
Males and females usually invest asymmetrically in offspring. In species lacking parental care, females influence offspring in many ways, while males only contribute genetic material via their sperm. For this reason, maternal effects have long been considered an important source of phenotypic variation, while paternal effects have been presumed to be absent or negligible. The recent surge of st...
