Abstract
Hybridization in the freshwater microcrustacean Daphnia occurs naturally and the interspecific hybrids have been found between several species, occupying many diverse types of freshwater habitats (e.g., lakes and ponds). A comparative analysis of gene expression from crosses of varied species of Daphnia is a powerful way to identify the evolutionary divergence of the genetic elements controlling the expression of genes. In this study, multiple within-species and between-species crossing experiments are performed. We then sequenced the transcriptomes of the obtained interspecific juvenile hybrids and to contrast the patterns of within-species gene expression divergence with between-species divergence. Transcriptomes were compared at 50 different sites on the genome to determine if crosses were true hybrids. We found that hybrid AroRL1 was a true cross and we plan to construct further sequencing on hybrid AroWash1.
