<meta content="Sex allocation theory predicts that parents should bias their reproductive investments toward the offspring
sex generating the greatest fitness return. When females are the heterogametic sex (e.g., ZW in butterflies, some
lizards, and birds), production of daughters is associated with an increased risk of offspring inviability due to the
expression of paternal, detrimental recessives on the Z chromosome. Thus, daughters should primarily be produced
when mating with partners of high genetic quality. When female sand lizards (Lacerta agilis) mate with genetically
superior males, exhibiting high MHC Class I polymorphism, offspring sex ratios are biased towards daughters, possibly
due to recruitment of more Z-carrying oocytes when females have assessed the genetic quality of their partners. If
our study has general applicability across taxa, it predicts taxon-specific sex allocation effects depending on which
sex is the heterogametic one." name="eprints.abstract" />

sex generating the greatest fitness return. When females are the heterogametic sex (e.g., ZW in butterflies, some
lizards, and birds), production of daughters is associated with an increased risk of offspring inviability due to the
expression of paternal, detrimental recessives on the Z chromosome. Thus, daughters should primarily be produced
when mating with partners of high genetic quality. When female sand lizards (Lacerta agilis) mate with genetically
superior males, exhibiting high MHC Class I polymorphism, offspring sex ratios are biased towards daughters, possibly
due to recruitment of more Z-carrying oocytes when females have assessed the genetic quality of their partners. If
our study has general applicability across taxa, it predicts taxon-specific sex allocation effects depending on which
sex is the heterogametic one.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available at www.blackwell-synergy.com
