Mature spermatozoa are permeable to foreign DNA and RNA molecules. Here I propose a model, whereby extrachromosomal genetic information, mostly encoded in the form of RNA in somatic cells, can cross the Weismann barrier and reach epididymal spermatozoa.

The bulk of studies of extrachromosomal heredity have had as experimental objects either eiliate protozoans or members of the plant kingdom. The former, although they have provided much enlightening, even spectacular information, do not fall within the ...

Extrachromosomal Inheritance: Yeast Linear Killer Plasmids as a Tool in Genetic Engineering
, 1995In principle, every stably replicated DNA species can serve as a vector for cloning foreign DNA in yeast or any other organism, in which such DNA is found. In strains of Saccharomyces cerevisiae a high copy number, autonomously replicating, extrachromosomal DNA element, the 2 µm DNA, was found to exist (Sinclair et al. 1967).

Two lines of Glossina m. morsitans, selected for susceptibility and refractoriness to infection with a single stock of Trypanosoma congolense, have now been shown to be susceptible or refractory to different stocks of T.
