polyploid

Polyploid wild plants of this species have been found in Mexico.

Some other organisms are polyploid, they have more than two sets of chromosomes.

Rare instances of polyploid mammals are known, but most often result in prenatal death.

Diploid and polyploid individuals may occupy different types of habitat.

Apomictic species or individual plants often have a hybrid origin, and are usually polyploid.

Reproduction of successful polyploid species is sometimes asexual, by parthenogenesis.

In some situations polyploid crops are preferred because they are sterile.

Plants important in agriculture such as tobacco or wheat are often polyploid, compared to their ancestral species.

Brewing strains are polyploid so mating aggregates do not occur.

This will cause many of the seeds to die and not germinate, but the ones that do come up will be polyploid plants.

Polyploid plants tend to be larger and better at flourishing in early succession habitats such as farm fields.

Polyploid animals are often sterile, so they often reproduce by parthenogenesis.

Old World populations are polyploid, and regarded as distinct subspecies, supporting the idea that the spread was not recent.

The resulting hybrid has the chromosomes of both plants and is thus similar to polyploid plants.

Polyploid lizards are also quite common and parthenogenetic.

All three polyploid species are apomictic species which breed true without pollination.

It is also possible for polyploid organisms to revert to lower ploidy by means of haploidisation.

Macronuclei are polyploid and undergo direct division without mitosis.

In plants, polyploid individuals are created frequently by a variety of processes, and once created usually cannot cross back to the parental type.

Many clandestine cultivators have started polyploid strains with colchicine.

Brewing yeasts are polyploid and belong to the Saccharomyces genera.

Polyploid types are labeled according to the number of chromosome sets in the nucleus:

Diploid or polyploid pollen grains produced by cytomixis may have a significant role in evolution.

He pointed out that, among other things, all of - Lansing's long-lived rotifers showed characteristics in common with polyploid individuals.

There are few naturally occurring polyploid conifers.

The zygoid state of a species may be diploid or polyploid.

Then becoming triploid or polyploid are later evolutionary steps of this "primary gametophyte".

However, it is still able to replicate its DNA and continue development, becoming polyploid.

For example, wheat is hexaploid (a kind of polyploid), meaning that it has six copies of its genome.

Mixoploidy refers to the presence of two cell lines, one diploid and one polyploid.

The results from polyploid and diploid cells should be identified and separately recorded from one another.

For example, common wheat is a polyploid with six sets of chromosomes, two sets coming originally from each of three different species.

The generic term polyploid is frequently used to describe cells with three or more sets of chromosomes (triploid or higher ploidy).

She studied the polyploid and diploid of chilodonella uncinata, as well as mutation inheritances found in them.

Hagerup, O. (1947) The spontaneous formation of haploid, polyploid, and aneuploid embryos in some orchids.

It is believed that the haploid condition of 10 chromosomes was likely derived by reduction from a higher (polyploid) ancestral number (Lewis, W. H. 1980).

Confirmation of shared and divergent genomes in the Glycine tabacina polyploid complex (Leguminosae) using histone H3-D sequences.

In particular, the structural and functional outcomes of polyploid Saccharomyces genomes strikingly reflect the evolutionary fate of plant polyploid ones.

Inhibition of Aurora B kinase by BI811283 in cancer cells leads to the formation of cells with severely abnormal numbers of chromosomes (polyploid).

The species is a polyploid and originated via hybridization of an East Asian Hordeum species with a close but extinct relative of Californian H. brachyantherum.

Cells or organisms with only one copy of each chromosome are called haploid; those with two copies are called diploid; and those with more than two copies are called polyploid.

Colla also was the first authority to recognize that both Musa acuminata and Musa balbisiana were wild ancestral species, even though the specimen he described was a naturally occurring seedless polyploid like cultivated bananas.

S. anglica is a fertile polyploid derived from the hybrid S.alterniflora x townsendii (S. alterniflora x S. maritima), first found when American S. alterniflora was introduced to southern England in about 1870 and came into contact with the local native S. maritima.

Duplication events that occurred long ago in the history of various evolutionary lineages can be difficult to detect because of subsequent diploidization (such that a polyploid starts to behave cytogenetically as a diploid over time) as mutations and gene translations gradually make one copy of each chromosome unlike its other copy.
