- Survival of the progeny obtained from artificial crossing of large parasitic anadromous and small nonparasitic resident European river lampreys Lampetra fluviatilis is analyzed. A high individual survival (~61% on average) up to the stage of prolarvae burrowing into ground confirms the absence of a postzygotic barrier between the lamprey forms. The obtained results are discussed in the framework of two theories: of paired species and of intraspecies diversity.
