Occurrence of heterozygosity in all individuals of a population at a large proportion of loci is best explained as non-recombinational or fixed heterozygosity resulting from allopolyploidy.
Heilborn (cited in Davies, 1956) held that the seeming lack of allopolyploidy in Carex might be attributable at least in part to this phenomenon, as the degeneration of all but one nucleus per PMC "prevents the formation of unreduced pollen dyads in any interspecific hybrid" (Davies, 1956: 351).
