| Given that cultivated peanut is a disomic polyploid, 20 linkage groups were expected. |
|
| Wheat was the first domesticated crop and is the youngest polyploid species among the agricultural crops. |
|
| In contrast, the somatic macronucleus is polyploid, divides amitotically, and is actively transcribed. |
|
| The Catipes group has amphimictic diploids and tetraploids and derived from them are all of the polyploid agamic complexes in the genus. |
|
| Plants often fertilize themselves to at least some extent, so polyploid species can arise from a single individual. |
|
| Formation of polyploid nuclei as a consequence of failure of chromosome segregation in the presence of ICRF-193 was also reported in HeLa cells. |
|
| Weak png mutations permit several transient S-M cycles to occur, producing embryos with a characteristic phenotype of multiple polyploid nuclei. |
|
| We also investigated a possible DMSO effect on the frequency of polyploid and endo-reduplicated cells by chromosome counting. |
|
| As the present sample did not include polyploid eudicots, a similar comparison for polyploids alone was not possible. |
|
| Most of the remaining plants regenerated are sterile haploid plants while a few partially sterile plants could be polyploid or aneuploid. |
|
| Furthermore, it can be shown to hold for PGE with male somatic diploidy and for polyploid apomixis as well. |
|
| Comparison of the measurements of nuclei from the groups nulligravida, gravida and pregnant made it clear, that polyploid nuclei must arise during pregnancy. |
|
| In all four cases the embryos produced by mutant females had a small number of apparently polyploid nuclei rather than the normal, large number of diploid syncytial nuclei. |
|
| Specimens identified as three separate species, based primarily on filament diameter and cell size, were determined to be polyploid races of a single species. |
|
| About 200,000 years ago, at nearly the same time that modern humans originated in Africa, two diploid grass species hybridized to form polyploid wheat in the Middle East. |
|
| As a result, these plants have proliferated as reproductively competent, polyploid species. |
|
| We also wished to explore patterns of gene evolution in polyploid cotton, using as a comparative framework orthologs from the diploid progenitors. |
|
| There are several polyploid subspecies, races, and forms occurring in different parts of the Northern hemisphere. |
|
| An organism with any multiple of the diploid number of chromosomes is said to be polyploid. |
|
| Could the alien species interbreed with a native species to produce a new species of aggressive polyploid invasive? |
|
|
|
| An individual with additional chromosome sets is called a polyploid. |
|
| Life history divergence on sympatric diploid and polyploid populations of brine shrimp Artemiaparthenogenetica. |
|
| The results may also indicate that hypotonic shock may play an important role in the initiation of some spontaneous polyploid aquatic organisms. |
|
| In the polyploid unisexual mole salamander females, a premeiotic endomitotic event doubles the number of chromosomes. |
|
| Evidence for genetic suppression of heterogenetic chromosome pairing in polyploid species of Solanum, sect. |
|
| Hybridization and polyploidy are also frequent within Isoetes, with several polyploid species that show intermediate morphologies between their parents. |
|
| Known under numerous synonymies applied to various parthenogenetic and polyploid morphs, differing in the shape and position of tubercula pubertatis. |
|
| Paraphyly of Tarasa and diverse origins of the polyploid species. |
|
| Alternative to production of polyploid fish, treatment of sperm with radiation prior to fertilization permits the production of gynogenetic offspring. |
