How clonal are clones? A quest for loss of heterozygosity during asexual reproduction in Daphnia magna

Dukić, Marinela ; Berner, Daniel ; Haag, Christoph R. ; Ebert, Dieter

In: Journal of Evolutionary Biology, 2019, vol. 32, no. 6, p. 619–628

Due to the lack of recombination, asexual organisms are predicted to accumulate mutations and show high levels of within‐individual allelic divergence (heterozygosity); however, empirical evidence for this prediction is largely missing. Instead, evidence of genome homogenization during asexual reproduction is accumulating. Ameiotic crossover recombination is a mechanism that could lead to...

A high-density genetic map reveals variation in recombination rate across the genome of Daphnia magna

Dukić, Marinela ; Berner, Daniel ; Roesti, Marius ; Haag, Christoph R. ; Ebert, Dieter

In: BMC Genetics, 2016, vol. 17, p. 137

Recombination rate is an essential parameter for many genetic analyses. Recombination rates are highly variable across species, populations, individuals and different genomic regions. Due to the profound influence that recombination can have on intraspecific diversity and interspecific divergence, characterization of recombination rate variation emerges as a key resource for population...

Local adaptation of sex induction in a facultative sexual crustacean: insights from QTL mapping and natural populations of Daphnia magna

Roulin, Anne C. ; Routtu, Jarkko ; Hall, Matthew D. ; Janicke, Tim ; Colson, Isabelle ; Haag, Christoph R. ; Ebert, Dieter

In: Molecular Ecology, 2013, vol. 22, no. 13, p. 3567–3579

Dormancy is a common adaptation in invertebrates to survive harsh conditions. Triggered by environmental cues, populations produce resting eggs that allow them to survive temporally unsuitable conditions. Daphnia magna is a crustacean that reproduces by cyclical parthenogenesis, alternating between the production of asexual offspring and the sexual reproduction of diapausing eggs (ephippia)....
