Data from: Male-biased sex allocation in ageing parents; a longitudinal study in a long-lived seabird ...
Optimal sex allocation is frequency-dependent, but senescence may cause behaviour at old age to be suboptimal. We investigated whether sex allocation changes with parental age, using 16 years of data comprising more than 2500 molecularly sexed offspring of more than 600 known-age parents in common t...
