Data from: Unidirectional diploid–tetraploid introgression among British birch trees with shifting ranges shown by restriction site-asso
- 负责人：
- DOI：
- doi:10.5061/dryad.815rj
- 摘要：
- rectional introgression between diploid Betula nana (dwarf birch) and tetraploid B. pubescens (downy birch) and also between B. pubescens and diploid B. pendula
Data from: Conservation genetics of Neotropical pollinators revisited: microsatellite analysis suggests that diploid males are rare in orchid bees

- 摘要：
- of diploid males, a result of loss of sex allele diversity in small hymenopteran populations with single locus complementary sex determination. Our analysis of 1010
Data from: Higher rate of tissue regeneration in polyploid asexual vs. diploid sexual freshwater snails
- 负责人：
- DOI：
- doi:10.5061/dryad.68nj4
- 摘要：
- . Antennae of triploid and presumptive tetraploid asexuals regenerated more rapidly than the antennae of diploid sexuals, but regeneration rate did not diffe
Data from: Interactions between genetic and ecological effects on the evolution of life cycles

- DOI：
- doi:10.5061/dryad.40qp5
- 摘要：
- Sexual reproduction leads to an alternation between haploid and diploid phases, whose relative length varies widely across taxa. Previous

- 摘要：
- a reference map of meiotic stages in diploid and tetraploid S. tuberosum using fluorescence in situ hybridisation (FISH) to differentiate indi
Data from: Invasion success in polyploids: the role of inbreeding in the contrasting colonization abilities of diploid versus tetraploid populations
- 负责人：
- DOI：
- doi:10.5061/dryad.pq6ts
- 摘要：
- . We conducted a breeding experiment (sib-mating vs. outcrossing) with 14 native diploid, 13 native tetraploid and 15 invasive tetraploid populations. We recorded
Data from: Strongly asymmetric hybridization barriers shape the origin of a new polyploid species and its hybrid ancestor

- 摘要：
- ween the haploid and diploid phases. Secondly, we compared growth rate plasticity between diploids with different numbers of heterozygous loci. Finally, we compared

- 摘要：
- The evolutionary stability of haploid-diploid life cycles is still controversial. Mathematical models indicate that niche differences between ploid
Data from: Evolution and systematics of polyploid Nigritella (Orchidaceae)

- 摘要：
- with predictions from embryological studies, diploid members of Nigritella are sexual and mostly out-crossing, whereas triploid, tetraploid and pentaploid members ar
