In spite of the two-fold reproductive advantage, asexual reproduction is not common in nature, likely due to the associated genetic deterioration or reduced genetic variation. To understand how genetic diversity is maintained in existing asexual populations, we investigated the genetic diversity and population structure of sympatric sexual and asexual populations of a parasitic wasp, Meteorus pulchricornis, using 614 genome-wide loci with single nucleotide polymorphisms. The genetic structures of the apomictic asexual populations were distinct, showing...
