Аннотация: Asexual reproduction is often considered as an evolutionary dead-end. However the mere existence of bdelloid rotifers - a large clade of putative ancient asexuals challenges this point of view. Several hundred thousand bdelloid rotifers have been examined but no males have been found so far. The possibility however exists that some form of cryptic sexual reproduction occurs in bdelloid rotifers. To address this possibility we have sequenced genomes of 10 Adineta vaga individuals. We use whole-genome polymorphism data to look for signatures of recombination in A.vaga population.
