Sexual conflict and sex allocation

There was an error in the above paper on page 660, in §2a. The fifth sentence in this section should have stated:

‘A startling example of sibling–sibling sexual conflict is provided by Korsten et al. (2009) who show that female Soay sheep with a male twin have a lower birth weight than females born with a female twin.’
