ESEB satellite meeting: Genomic signatures and consequences of sex and asexuality
What is this about?
Sex, including outcrossing with meiosis, is by far the most common form of reproduction in eukaryotes. However, under similar ecological and genetic conditions, an individual undergoing asexual reproduction without outcrossing, will generate more offspring (each of which is itself capable of generating offspring) than a sexual sibling. It is thought that this cost of sex is offset by the benefits conferred by the exchange of genetic material, thus avoiding mutational meltdown (Muller's ratchet) and genomic decay. Sexual reproduction is realised in an impressive array of different strategies. Still, asexual species are found on terminal branches in many unrelated clades throughout the eukaryotic tree of life. The availability of high quality phased genomes only now allows us, to study the genomic underpinnings of transitions in reproductive modes, to compare the long-term effects of sex and asexuality on genomes, and to analyse the functional mechanisms of the loss and even regain of sex.
In this two half-days symposium we will bring together scientists working on genomic aspects of sex and asexuality in organisms across the eukaryotic tree of life and invite talks on - genomics and genomic models of the drivers of loss of sex/gain of sex - analyses of the consequences of loss of sex on the genomic level - genomic changes accompanying transitions in reproductive systems such as from unisexual or hermaphroditic to seperate sexes, or from environmental sex determination to genetic sex determination

Like to give a talk?
Tell the community about your latest, coolest projects and results.
We invite abstracts for short (15 min.) talks through the ESEB submission system. Abstracts should be concise and not exceed a 250 word limit with a max. 100 characters title. Submission deadline is the 15th of May, 23:59 CET.
We aim to allocate talks carefully looking out for gender balance and diversity of speakers. 4 talk slots will be reserved to students, who are very much invited to take part in the conference and present their work.
Registration and abstract submission through ESEB.
