Genome-wide allele-specific expression in obligately asexual Daphnia pulex and the implications for the genetic basis of asexuality. Daphnia pulex isolate:PA42

We identified genes with allele-specific expression (ASE) in a Daphnia pulex population, in which obligate parthenogens (OP) and cyclical parthenogens (CP) coexist, with the OP clones having been originally derived from hybridization between CP D. pulex and its sister species, D. pulicaria.
