impaternata (Figure 1) is an
allodiploid species with unmatched haploid sets of chromosomes (n=5 or 14, 2n=19), identifying it as a female-only species of hybrid origin [1, 2].
Conclusions.--Several genetic studies have characterized
allodiploid parthenogenetic A.
Unreduced
allodiploid spores develop into gametophytes capable of producing allotetraploid sporophytes through suiting or sib meting.
whitei represent the only known example of hemiclonal and clonal reproduction shared by the same
allodiploid hybrids, which are also indistinguishable on an allozymic basis (Mantovani et al.
Habitat characteristics of the three peripheral sites north of the Rio Grande known to be inhabited by the
allodiploid parthenogenetic species Cnemidophorus laredoensis A (C.
Chromatid interchange in
allodiploid maize-Tripsacum hybrids.
In these cases, triploids have been generated by the addition of a haploid genome from a biparental species to that of an
allodiploid congeneric parthenogen or gynogen.
