| No significant increase in cells with chromosomal aberrations, polyploidy or endoreduplication was observed at the concentrations analyzed. |
|
| The extent of polyploidy in target taxa and related species was generally unknown. |
|
| An increase in polyploidy may indicate that a chemical has the potential to induce numerical aberrations. |
|
| An increase in polyploidy may indicate that the test substance has the potential to induce numerical chromosome aberrations. |
|
| They were able to identify or confirm two dozen examples of polyploidy in these species. |
|
| For instance, in humans, fetuses affected by polyploidy often are spontaneously aborted early in pregnancy. |
|
| Sterile fish, shellfish or molluscs could be produced by induced polyploidy. |
|
| Hybridization and polyploidy have undoubtedly spawned many grass species, as, for example, the wheats. |
|
| Stomatal size in fossil plants: evidence for polyploidy in majority of angiosperms. |
|
| Evolution of reproductive systems, pollination, polyploidy and hybridization in flowering plants. |
|
| Little is known about the transition from diploidy to polyploidy but in some species, triploids are thought to function as intermediates in this transition. |
|
| In this study, segmental duplicated genes contained both transpositional duplicates and polyploidy orthologs. |
|
| The limitations of array CGH is that it cannot detect balanced translocations or polyploidy, as it only detects copy number variation. |
|
| Scientific review of literature indicates that polyploidy in vitro is induced by many types of insult and does not necessarily reflect a potential for aneuploidy. |
|
| This phenomenon, which can be observed in different genomes, may also partly explain what is called polyploidy, that is, the fact of possessing several copies of given chromosomes instead of just one pair. |
|
| Common genetic features observed in the immigrant species of Lepidium are autogamy and polyploidy, which helps their establishment in new habitats. |
|
| An estimate of the incidence of polyploidy in the family, which is up to about 80 percent, indicates how frequently hybridization has taken place in grasses. |
|
| Numerical aberration, however, was observed at higher concentrations of retapamulin, thus indicating that there was a tendency to increase the number of polyploidy cells. |
|
| In order to improve the quality of Community beet seed, certain requirements must be laid down as to, amongst others, polyploidy, monogermity, segmentation, analytical purity, germination and moisture content. |
|
| However, polyploidy does not account for all variation within the species. |
|
|
|
| This type of association indicates that Maca is a disomic polyploidy. |
|
| Use of a cell hybrid test system to demonstrate that benomyl induces aneuploidy and polyploidy. |
|
| Though the purpose of the test is to detect structural chromosome aberrations, it is important to record polyploidy and endoreduplication when these events are seen. |
|
| Usually the spores provide the best characters for distinguishing species within Isoetes, but these can vary in size because of polyploidy and hybridization. |
|
| Neoendemism refers to species that have recently arisen, such as through divergence and reproductive isolation or through hybridization and polyploidy in plants. |
|
| A second hypothesis stated that ferns accumulated chromosomes through cycles of polyploidy events, followed by a return to genetic diploidy through gene silencing. |
|
| DeNovoMAGIC proprietary algorithms enable the full mapping of even the most large and complex genomes, including heterozygous and polyploidy genomes. |
|
| Hybridization and polyploidy are also frequent within Isoetes, with several polyploid species that show intermediate morphologies between their parents. |
|
| As they mature, the DNA is replicated several times but the cell does not divide, a condition known as polyploidy which allows cells to increase in size. |
|
| Hybridization and chromosome pairing studies have to some extent revealed the species relationship and the progenitors of some of the polyploidy species have been determined. |
|
| In this case, the inheritance or descent is not by diploidy but the polyploidy of parents, siblings, peers, teachers, relatives, and society in general. |
|
| Next is an agglutination of chromosomes and after that is polyploidy. |
|
| Polyploidy has had an enormous influence on the evolution of grasses, and it is estimated that all grasses are polyploids. |
|
| Polyploidy or polyteny may account for this large cellular DNA content, but studies of DNA reassociation kinetics do not support this hypothesis. |
