      The evening primrose plant family (Onagraceae) offers an ideal system to test predictions relating to the role of sexual recombination and segregation on diversification (Fig. 1). In many evening primrose species […] .

      Specifically, we ask whether sexual evening primrose plant lineages (Onagraceae) have faster rates of adaptive molecular evolution and altered gene expression of a class I chitinase, a gene implicated in defence against pathogens, than functionally asexual evening primrose lineages.
