Polyploidy - Wikipedia
Polyploidy is a condition in which the cells of an organism have more than two paired sets of (homologous) chromosomes.

2024年8月19日 · multiploid (plural multiploids) A cell or organism having multiple copies of each chromosome.
Relative DNA content in diploid, polyploid, and multiploid species …
Multiploid species are common with most of them bearing sexual diploid and apomictic tetraploid or other ploidy levels. DNA content in the embryo and the endosperm was measured by flow cytometry in a seed-by-seed analysis of 47 species including 77 different entities.
Ploidy - Wikipedia
Ploidy (/ ˈplɔɪdi /) is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Here sets of chromosomes refers to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair—the form in which chromosomes naturally exist.

Polyploidy is the heritable condition of possessing more than two complete sets of chromosomes. Polyploids are common among plants, as well as among certain groups of fish and amphibians. For...
Frequent allelic imbalance at the ATM locus in DNA multiploid ...
2001年10月9日 · To clarify the role of DNA multiploidy in colorectal cancer, we analysed allelic imbalance involving the ATM gene, localized to chromosome 11q22-23 and thought to be involved in genetic stability,...
Useful diversity via multiploidy - IEEE Xplore
Abstract: A multiploid genetic algorithm (GA) incorporates several candidates for each gene within a single genotype, and uses some form of dominance mechanism (most simply, an encoded choice) to decide which choice of each gene is active in the phenotype. We explore a simple multiploid model.

2012年6月15日 · Polyploids can be formed in various ways. Among them, hybrid organisms formed by distant hybridization could produce unreduced gametes and thus generate offspring with doubled chromosomes, which is a fast, efficient method of polyploidization.

Most organisms have a ploidy level of 2, meaning that they have two sets of chromosomes due to presence of homologous pairs. However, some plants are multiploid, meaning they can have ploidy levels greater than 2. The table shows possible multiploid levels …
