Unreduced gametes: meiotic mishap or evolutionary mechanism?

AS Mason, JC Pires - Trends in Genetics, 2015 - cell.com
Unreduced gametes (gametes with the somatic chromosome number) are known to facilitate
polyploid formation. Unreduced gametes result from a plethora of different mechanisms …

Evolutionary dynamics of unreduced gametes

JM Kreiner, P Kron, BC Husband - Trends in Genetics, 2017 - cell.com
Unreduced gametes, which have the somatic (2n) chromosome number, are an important
precursor to polyploid formation and apomixis. The product of irregularities in meiosis, 2n …

Pure polyploidy: closing the gaps in autopolyploid research

JP Spoelhof, PS Soltis, DE Soltis - Journal of Systematics and …, 2017 - Wiley Online Library
Polyploidy (whole‐genome duplication, WGD) is an integral feature of eukaryotic evolution
with two main forms typically recognized, autopolyploidy and allopolyploidy. In plants, a …

Genetic and epigenetic alterations after hybridization and genome doubling

O Paun, MF Fay, DE Soltis, MW Chase - Taxon, 2007 - Wiley Online Library
Hybridization and polyploidization are now recognized as major phenomena in the
evolution of plants, promoting genetic diversity, adaptive radiation and speciation. Modern …

Endopolyploidy as a potential driver of animal ecology and evolution

M Neiman, MJ Beaton, DO Hessen… - Biological …, 2017 - Wiley Online Library
Endopolyploidy–the existence of higher‐ploidy cells within organisms that are otherwise of a
lower ploidy level (generally diploid)–was discovered decades ago, but remains poorly …

Cryptic fitness advantage: diploids invade haploid populations despite lacking any apparent advantage as measured by standard fitness assays

AC Gerstein, SP Otto - PloS one, 2011 - journals.plos.org
Ploidy varies tremendously within and between species, yet the factors that influence when
or why ploidy variants are adaptive remains poorly understood. Our previous work found that …

Non-Mendelian phenomena in allopolyploid genome evolution

B Liu, JF Wendel - Current Genomics, 2002 - ingentaconnect.com
Perhaps all flowering plants have experienced one or more episodes of polyploidization at
some time in their evolutionary history. Recent evidence indicates that this genome doubling …

Polyploidy and its effect on evolutionary success: old questions revisited with new tools

A Madlung - Heredity, 2013 - nature.com
Polyploidy, the condition of possessing more than two complete genomes in a cell, has
intrigued biologists for almost a century. Polyploidy is found in many plants and some animal …

Genetic divergence and the number of hybridizing species affect the path to homoploid hybrid speciation

AA Comeault, DR Matute - Proceedings of the National …, 2018 - National Acad Sciences
Hybridization is often maladaptive and in some instances has led to the loss of biodiversity.
However, hybridization can also promote speciation, such as during homoploid hybrid …

Hybridization, speciation and novelty

PS Soltis - Journal of Evolutionary Biology, 2013 - academic.oup.com
Hybridization has been alternatively viewed as evolutionary noise (eg Wagner, 1970) and
an engine of biodiversity (eg Arnold, 1997), and debate continues over the role of …
