Сгенерированная сводка:Самцы передают свое экологически приобретенное состояние через отцовское воздействие на размер тела потомства.Мы манипулировали состоянием самцов и скрещивали самок с двумя самцами в высоком или низком состоянии в полностью скрещенном дизайне.Хотя второй самец дал большую часть потомства, на размер потомства повлияло состояние первого самца.Abstract:Newly discovered non-genetic mechanisms break the link between genes and inheritance, thereby also raising the possibility that previous mating partners could influence traits in offspring sired by subsequent males that mate with the same female (‘telegony’). In the fly, males transmit their environmentally acquired condition via paternal effects on offspring body size. We manipulated male condition, and mated females to two males in high or low condition in a fully crossed design. Although the second male sired a large majority of offspring, offspring body size was influenced by the condition of the first male. This effect was not observed…
