Triploid and tetraploid chromosomes are examples of polyploidy. Polyploidy is a condition in which the cells of an organism have more than two paired sets of (homologous) chromosomes.

In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.

Polyploid organisms are eukaryotes that have more than two complete sets of chromosomes (one from each parent or ancestor) in somatic and germline cells of animals, fungi, and plants.

Cells (and their owners) are polyploid if they contain more than two haploid (n) sets of chromosomes; that is, their chromosome number is some multiple of n greater than the 2n content of diploid cells. …

Jul 31, 2025 · Polyploidy describes a genetic condition where an organism or cell possesses more than two complete sets of chromosomes. Most species with cells containing nuclei, known as eukaryotes, …

Polyploid organisms contain more than two sets of chromosomes. Many of the plants we eat are polyploids, such as some varieties of wheat and strawberries.

Polyploidy, which results from whole-genome duplication, is a fundamental complement to vertical copying. Both organismal and cell polyploidy can emerge via premature cell cycle exit or via cell-cell …

The meaning of POLYPLOID is having or being a chromosome number that is a multiple greater than two of the monoploid number.

Polyploidy occurs when an organism has more than two complete sets of chromosomes, a common occurrence in plants, while aneuploidy refers to an abnormal number of chromosomes that is not an …

Polyploidy involves three or more times the haploid number of chromosomes. Polyploid types are termed according to the number of chromosome sets in the nucleus: triploid (three sets; 3n), …
