• Investigating the origin of parthenogenesis and ploidy level in Dahlica fennicella (Lepidoptera: Psychidae) 

  Chevasco, Verónica; Elzinga, Jelmer Anne; Galarza, Juan; Mappes, Johanna; Grapputo, Alessandro (Finnish Zoological and Botanical Publishing Board, 2013)

  The theories for the predominance of sexual reproduction predict that parthenogens should have no long-term evolutionary potential due to the lack of genetic recombination, despite short term advantages. Although parthenogenesis ...

• Large variation in mitochondrial DNA of sexual and parthenogenetic Dahlica triquetrella (Lepidoptera: Psychidae) shows multiple origins of parthenogenesis 

  Elzinga, Jelmer Anne; Jokela, Jukka; Shama, Lisa NS (BioMed Central, 2013)

  Background: Obligate parthenogenesis is relatively rare in animals. Still, in some groups it is quite common and has evolved and persisted multiple times. These groups may provide important clues to help solve the ‘ paradox ...

• Variation in parasite resistance of Arctic charr, Salvelinus alpinus, between and within sympatric morphs 

  Karvonen, Anssi; Beck, Samantha V.; Skúlason, Skúli; Kristjánsson, Bjarni K.; Leblanc, Camille A. (Wiley-Blackwell, 2021)

  Genetic variation in resistance against parasite infections is a predominant feature in host–parasite systems. However, mechanisms maintaining genetic polymorphism in resistance in natural host populations are generally ...

• Phylogeny and evolution of parthenogenesis in Finnish bagworm moth species (Lepidoptera : Psychidae : Naryciinae) based on mtDNA-markers 

  Grapputo, A.; Kumpulainen, T.; Mappes, J. (Finnish Zoological and Botanical Publishing Board, 2005)

  We investigated species diversity and evolution of parthenogenesis among bagworm moth species of Dahlica and Siederia using mitochondrial DNA sequencing. Parthenogenesis is rare among Lepidoptera other than Psychidae. ...

• Genetic diversity in populations of asexual and sexual bag worm moths (Lepidoptera: Psychidae) 

  Grapputo, Alessandro; Kumpulainen, Tomi; Mappes, Johanna; Parri, Silja (BioMed Central, 2005)

  BACKGROUND: Despite the two-fold cost of sex, most of the higher animals reproduce sexually. The advantage of sex has been suggested to be its ability, through recombination, to generate greater genetic diversity than ...
