A Male-Specific Genetic Map of the Microcrustacean Daphnia pulex Based on Single-Sperm Whole-Genome Sequencing.
Genetic linkage maps are critical for assembling draft genomes to a meaningful chromosome level and for deciphering the genomic underpinnings of biological traits. The estimates of recombination rates derived from genetic maps also play an important role in understanding multiple aspects of genomic evolution such as nucleotide substitution patterns and accumulation of deleterious mutations. In ...
متن کاملHybridization and the Origin of Contagious Asexuality in Daphnia pulex.
Hybridization plays a potentially important role in the origin of obligate parthenogenesis (OP) in many organisms. However, it remains controversial whether hybridization directly triggers the transition from sexual reproduction to obligate asexuality or a hybrid genetic background enables asexual species to persist. Furthermore, we know little about the specific genetic elements from the diver...
متن کاملProposal to Sequence the Genome of Daphnia Pulex
Recent characterization of the complete genomic sequences of multiple eukaryotes and prokaryotes is rapidly increasing our ability to understand how genome structure evolves and how gene expression and individual performance is modified in response to environmental challenges. These advances hold the promise of making a direct connection between the genome and the phenotype of organisms in popu...
متن کاملInsertion Polymorphisms of Mobile Genetic Elements in Sexual and Asexual Populations of Daphnia pulex
Transposable elements (TEs) constitute a substantial portion of many eukaryotic genomes, and can in principle contribute to evolutionary innovation as well as genomic deterioration. Daphnia pulex serves as a useful model for studying TE dynamics as a potential cause and/or consequence of asexuality. We analyzed insertion polymorphisms of TEs in 20 sexual and 20 asexual isolates of D. pulex acro...
متن کاملLocalization of the genetic determinants of meiosis suppression in Daphnia pulex.
Although approximately 1 in 10,000 animal species is capable of parthenogenetic reproduction, the evolutionary causes and consequences of such transitions remain uncertain. The microcrustacean Daphnia pulex provides a potentially powerful tool for investigating these issues because lineages that are obligately asexual in terms of female function can nevertheless transmit meiosis-suppressing gen...
