Daddy Issues: Paternal Effects on Phenotype
The once popular and then heretical idea that ancestral environment can affect the phenotype of future generations is coming back into vogue due to advances in the field of epigenetic inheritance. How paternal environmental conditions influence the phenotype of progeny is now a tractable question, and researchers are exploring potential mechanisms underlying such effects.
متن کاملPaternal effects on early embryogenesis
Historically, less attention has been paid to paternal effects on early embryogenesis than maternal effects. However, it is now apparent that certain male factor infertility phenotypes are associated with increased DNA fragmentation and/or chromosome aneuploidies that may compromise early embryonic development. In addition, there is a growing body of evidence that the fertilizing sperm has more...
متن کاملMaternal and paternal condition effects on offspring phenotype in Telostylinus angusticollis (Diptera: Neriidae).
It is widely recognized that maternal phenotype can have important effects on offspring, but paternal phenotype is generally assumed to have no influence in animals lacking paternal care. Nonetheless, selection may favour the transfer of environmentally acquired condition to offspring from both parents. Using a split-brood, cross-generational laboratory design, we manipulated a key environmenta...
متن کاملWidespread differential maternal and paternal genome effects on fetal bone phenotype at mid-gestation.
Parent-of-origin-dependent (epi)genetic factors are important determinants of prenatal development that program adult phenotype. However, data on magnitude and specificity of maternal and paternal genome effects on fetal bone are lacking. We used an outbred bovine model to dissect and quantify effects of parental genomes, fetal sex, and nongenetic maternal effects on the fetal skeleton and anal...
متن کاملEvolution. Who's your daddy?
T he recognition that birds are theropod dinosaurs has redefined the science of ornithology as extant dinosaur biology (1). The placement of birds in a detailed evolutionary context has led to exciting discoveries about the commonalities birds share with their dinosaur ancestors, including feathers (2) and possibly flight (3). Insights have been gained into both the origins of avian biology and...
