The importance of parental contributions to offspring development and subsequent performance is self-evident at a genomic level; however, parents can also affect offspring fitness by indirect genetic and environmental routes. The life history strategy that an individual adopts will be influenced by both genes and environment; and this may have important consequences for offspring. Recent research has linked telomere dynamics (i.e. telomere length and loss) in early life to future viability and longevity. Moreover, a number of studies have reported a heritable component to telomere length across a range of vertebrates, though the effects of other parental contribution pathways have been far less studied. By using wild Atlantic salmon with different parental life histories in an experimental split-brood IVF mating design and rearing the resulting families under standardised conditions, we show that there can be significant links between parental life history and offspring telomere length (studied at the embryo ... : Embryo relative telomere lengthData contained in this spread sheet relates to the linear mixed model assessing variation in embryo relative telomere length.Variation in embryo RTL.xlsxFry relative telomere lengthData contained in this spread sheet relates to the linear mixed model assessing variation in fry relative telomere length.Variation in fry RTL.xlsxParental relative telomere lengthData contained in this spread sheet relates to the general linear model assessing variation in parental relative telomere length.Variation in parental RTL.xlsxSperm relative telomere lengthData contained in this spread sheet relates to the general linear model assessing variation in sperm relative telomere length.Variation in sperm RTL.xlsx ...
