Detailed explanation-1: -polyploidy, the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number.

Detailed explanation-2: -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 instance, some salamanders, frogs, and leeches are polyploids.

Detailed explanation-3: -A haploid cell (n) has 23 chromosomes (typically in the ovum or sperm). If a cell’s chromosomes are an exact multiple of 23 (46, 69, 92 in humans), those cells are referred to aseuploid. Polyploid cells are euploid cells with more than the normaldiploid number of 46 (2n) chromosomes: 3n, 4n.

Detailed explanation-4: -Polyploidy. Polyploidy is the state where all cells have multiple sets of chromosomes beyond the basic set, usually 3 or more.

Detailed explanation-5: -This is because the chromosomes can still pair up during meiosis and produce functional gametes. This explains why most naturally occurring polyploids have an even number of chromosome sets.
