In contrast to Arabidopsis and poplar, the genomes of grape (Vitis vinifera) and
papaya have had a more static duplication history, showing only a widely shared
hexaploidy event embedded at a deep and poorly resolved position within the ...

Fundamentals of Cytogenetics and Genetics
Hexaploidy: Origin of bread wheat (Triticum aestivum) is the best example of
hexaploidy. Wheat species consist of three genomic groups, according to their
chromosome numbers. 1. Einkorn group (2n = 14): genome-A - T riticum

hexaploidy through 2n + n hybridization, and (ii) a change from hexaploidy to
triploidy by meiosis and parthenogenetic development of the embryo. From
triploidy to tetraploidy the pathway is as previously described (2n + n
hybridization) and ...

Biology, Conservation and Sustainable Development of Sturgeons
In fact, in the case of autopolyploidy, hexaploidy may arise in two ways: (1) by the
fertilization of a diploidized egg from tetraploid species (~250 chromosomes) by
sperm from the same species (~125 chromosomes); (2) by fertilization of a ...

Hexaploidy induced by higher NaCl bred true for at least 25 cell generations after
being removed from NaCl exposure. The hexaploidy could not be correlated with
several phenotypic changes associated with plants regenerated from adapted ...

Plant Reproductive Ecology : Patterns and Strategies: ...
The reason for the association between homostyly and hexaploidy is unclear.
Hexaploids synthesized using colchicine remain distylous, indicating that at its
inception hexaploidy per se does not cause homostyle formation.107 Cytological

Jon and Lesley Lovett-Doust Professor of Biology the University of Windsor, 1988
Hexaploidy to some extent simplifies genetic analysis, not least because whole
chromosomes may be eliminated without affecting survival, and the differences
between the 41-chromosome "mono- somic" individual and the normal 42- ...
