Unreduced gametes are relatively common in Fragaria, and allopolyploid and autopolyploid species have been discovered (Hancock, 1999).
Unlike barrel medic, however, alfalfa is a heterozygous, out-crossing species (Smith, 1993) with a large and complex, autopolyploid genome.
angustifolium has a selfing rate similar to diploids, and also runs counter to the observation that all known naturally occurring autopolyploid angiosperms are outcrossing (Stebbins 1957; MacKey 1970) and that there are no examples of successful, selfing autopolyploid crop plants (Bingham 1980).
