- Paternal inheritance in parthenogenetic forms of the planarian
Based on a comparison of parents and offspring, using highly polymorphic microsatellites, we demonstrate the incorporation of paternal alleles in about 5% of the offspring We detected two

- How does planaria spread? – The Institute for Environmental Research . . .
Planaria spread primarily through asexual reproduction via fragmentation, where a single worm divides into multiple pieces, each regenerating into a complete individual Additionally, some species reproduce sexually, laying eggs that contribute to their spread to new environments
- The More the Merrier? - MIT Mathematics
The size of the parent worm can be inferred by summing the sizes of all fragments, and the clutch area is defined as the sum of the areas of all offspring pieces Thus, the total clutch area is given by the size of the parent worm minus the size of the head piece
- How Does Planaria Reproduce? Asexual and Sexual Methods
After a period of development, which can take several weeks, the offspring hatch from the cocoon as miniature versions of the adult planarian Planaria flatworms reproduce using dual strategies: complex mating and radical self-renewal powered by specialized stem cells
- Annual rhythmicity in the switching of reproductive mode in planarians
Species of planarians include both asexually reproducing individuals (reproduce through fission and regeneration) and sexually reproducing individuals (hermaphrodites that mate to produce cocoons) While some individuals can switch between the asexual and sexual modes of reproduction
- Mechanics dictate where and how freshwater planarians fission
Whether a planarian divides pre- or post-pharynx has a significant effect on its offspring, because it determines birth size and thus offspring survival and reproductive success (7)
- Let it rip: the mechanics of self-bisection in asexual planarians . . .
To predict the number of offspring an S-planarian could produce, we divided the parent worm area by the average area of the tail offspring and compared it to the actual observed number of offspring of the same S-planarians
- To Each His Own - Springer
Despite these geographic differences, all three species share a similar morphology, food and habitat preferences (slow running and still water), and reproduce by transverse division
