Polyploidy - Wikipedia
This image shows haploid (single), diploid (double), triploid (triple), and tetraploid (quadruple) sets of chromosomes. 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 chromosomes.

Tetraploidy - an overview | ScienceDirect Topics
Tetraploidy is an infrequent chromosomal abnormality, but triploidy occurs fairly often. Most triploid embryos miscarry in the first trimester. In approximately 20% of first-trimester spontaneous abortions, the conceptus is found to have a triploid karyotype.
Tetraploidy and tumor development - PMC - PubMed Central …
Tetraploid cells, which contain a doubled chromosomal content, are known to facilitate tumorigenesis [1]. Two specific characteristics of tetraploid cells play major roles in promoting neoplastic transformation. First, proliferating tetraploid cells are genomically unstable and accumulate both numerical and structural chromosomal abnormalities.
The consequences of tetraploidy and aneuploidy
Dec 1, 2008 · Tetraploidization can initiate chromosomal instability (CIN), probably owing to supernumerary centrosomes and the doubled chromosome mass. CIN, in turn, might persist or soon give way to a stably propagating but aneuploid karyotype. Both CIN and stable aneuploidy are commonly observed in cancers.
Tetraploidy - an overview | ScienceDirect Topics
Tetraploidy refers to cells that have double the number of chromosomes compared to normal cells (4N). In BE, aneuploidy has been correlated with the progression to EA [48,49]. An increase in 4N (G2/tetraploid) cells predicts progression to aneuploidy. Moreover, the development of 4N abnormalities is correlated with inactivation of the p53 gene.
Tetraploidy in cancer and its possible link to aging - PMC
Tetraploidy, a condition in which a cell has four homologous sets of chromosomes, is often seen as a natural physiological condition but is also frequently seen in pathophysiological conditions such as cancer.
Tetraploidy - an overview | ScienceDirect Topics
Tetraploidy refers to a rare chromosomal abnormality characterized by the presence of four sets of chromosomes instead of the usual two sets. It is often associated with multiple congenital anomalies and is typically not compatible with survival beyond the newborn period. You might find these chapters and articles relevant to this topic.
Tetraploid | definition of tetraploid by Medical dictionary
The state of a cell nucleus containing three or more haploid sets. Cells containing three, four, five, or six multiples are referred to, respectively, as triploid, tetraploid, pentaploid, and hexaploid.
